“How many 12 volt batteries do I need to power an air conditioning unit?” This article will help you answer that question, so don’t worry. To run an air conditioner, you’ll need at least four 12 V batteries.
We’ll get started right away by scrolling down and reading the entire article.
What Are The Different Kinds Of Batteries For My Air Conditioner?
The many sorts of air conditioners will be discussed before we get to the numbers you need to operate your air conditioner.
It’s possible to cool your room using four different types of batteries that can be taken with you at all times. They’re:
#1. Cell batteries that are flooded
The most common form of battery on the market is a flooded battery. Vehicles, power supplies, and self-sufficient energy systems all make use of these wet or flood sorts of power sources.
To ensure optimal operation, they contain liquids that must be tested and maintained. The fluid electrolyte-containing medium in flooded batteries is used to create a chemical reaction.
The acid in the battery’s liquid will begin to react with the lead plates as soon as the battery is turned on. The system receives an electric current as a result of the interaction. When you go with flooded cell batteries, you get the best of both worlds: reliable power backup and convenient energy storage.
When compared to AGM or glass mat batteries, which absorb energy, these are more affordable options for air conditioning needs.
Batteries with flooded cells, on the other hand, need more frequent maintenance and are more likely to be destroyed. Temperature fluctuations may also affect the electrolyte solution in these batteries, which could affect the performance of the battery.
#2. Absorbed glass mat batteries
There is a special glass mat border inside AGM batteries, which allows the electrolyte to be tapered between the plates of energy inside. These batteries are also known as glass mat batteries. The battery is also unique in that it has a unique structure that allows fiberglass to mix with the electrolyte and store the liquid in a dry or suspended manner, unlike conventional batteries that are liquid.
The electrolyte in AGM batteries is transported between the glass mats onto the plates of the battery and generates electricity. Glass mats contain electrolytes that are suitable for the system and prevent electrolytes from spilling when they are moved.
It’s also possible to utilize AGM batteries that don’t require any watering or maintenance. They are easier to maintain than flooded cells. AGM batteries, on the other hand, should not be under or overcharged because doing so could harm the battery’s lifespan.
These batteries are commonly used in solar and wind power systems. Battery-powered UPS systems and electronic auto servicing can also benefit from their use.
#3. Lithium battery containing phosphate
To generate power, phosphate and lithium are combined in these batteries. Lithium phosphate batteries are incredibly portable thanks to their small size and light weight. A portable power source like this one means that you won’t have to worry about running out of battery space.
#4. Tesla battery modules
Tesla’s electric vehicles primarily make use of the company’s batteries. Instead of lithium phosphate-based batteries, these batteries use lithium-ion batteries.
In a normal Tesla vehicle, there are 16 modules, each with a 24 V output, that are connected together. Compared to lithium phosphate batteries, one module can be compared to four at half the price. This makes them a serious threat.
The 12 Volt Batteries To Run An Air Conditioner
If you’re wondering how many 12 volt batteries are needed to power an air conditioner, this article is for you! For cell batteries that are flooded, 20-24 batteries with 12 V 100 Amp-hour capacity can be purchased.
You can run your air conditioner for about eight hours if you put this amount in your tank. The number of batteries you’ll need to run an air conditioner if you have 6 V flooded batteries is somewhere from 12 to 14.
AGM batteries, on the other hand, necessitate 14-18 12 V 100 Amp Hour cells in order to power the AC. Purchasing 8-12 batteries with a 6 V, 150 amp capacity is also an option for air-cooling. 12-16 12 V 100 Amp Hour lithium phosphate batteries are also required.
Finally, you’ll just need three Tesla batteries to power the air conditioning machine for up to eight hours of use. It is true that using batteries to power an air conditioner might be a challenge, but it is necessary to learn about electronics in order to chill your areas while on the go.
How much energy does an air conditioner use?
These factors influence the amount of energy (Wh or kWh) that an air conditioner uses:
- The air conditioner’s size or capacity (in BTUs)
- a system’s age and performance (SEER or EER ratings)
- Temperatures outside are rising.
- The insulation’s quality
When it comes to energy consumption, the size, model, and operating circumstances of your air conditioner will all influence how much power it uses. There are a few methods for figuring out how much energy is being used.
Estimation is the quickest and most straightforward method.
How to estimate the energy consumption of your air conditioner?
An appliance’s wattage (in W or kW) and usage time (hours) can be used to calculate its energy consumption (in Wh or kWh):
(Watt-hours) = Power (Watts) x Usage Time (Hour) (hours)
If an appliance had no duty cycle or variable speed drive, this would be accurate. Devices that function at full capacity all the time are not included in this equation.
In this regard, light bulbs stand out as a particularly illustrative case study. The wattage of a light bulb can be used to estimate the amount of energy it consumed when it is turned on for a specific amount of time.
If a 50-watt light bulb is left on for four hours, you can figure out how much energy it used this way:
(Watt-hours) = Power (Watts) x Usage Time (Hour) (hours)
Electricity Use (Watt-Hour) = 50 Watts multiplied by 4 hours
200 Watt-hours of energy are required to complete this project.
How are air conditioners different?
When it comes to your air conditioner, there are two options:
- Even when it’s turned on, it doesn’t always work.
- Alternatively, it isn’t always running at full capacity.
You’ll get a worst-case estimate if you utilize the formula above.
With a few simple rules of thumb, you can still estimate your air conditioner’s energy consumption over time using the wattage and the amount of time it’s been running.
What’s the best rule of thumb? That’s easy. Simply divide by 0.75.
When it comes to air conditioning, a 5000 BTU window unit that utilizes 400 watts of power is an excellent case study If this air conditioner is left running for four hours, the following is an estimate of its energy consumption:
Consumption of energy (Watt-hours) = Power Use (Watts) x Time Spent (Hours) x 0.75
400 Watts × 4 hours x 0.75% = 400 Watt-hours (Watt-hours)
1200 Watt-hours of energy use (Watt-hours)
Higher multiples are an option if the temperature is really high or if the air conditioner is rarely turned off (0.9 for example).
The wattage of your air conditioner can be found here if you’re unsure: How much power is consumed by an air conditioner?
In the case of air conditioners, the results of these computations are, once again, simply rough estimations. Measurement is the best and most accurate method for determining the energy usage of your air conditioner.
How to measure the energy consumption of your air conditioner?
You’ll need an Electricity Monitoring Device if you want to keep track of how much energy your air conditioner uses over time.
Kill-A-Watt meters may be used with most 110-130 Volt air conditioners that plug into the wall (or an inverter) and run at this voltage.
You can leave your air conditioner on for as long as you normally would after plugging in the monitoring device.
When you press the purple KWH button, the device will show you how much energy your air conditioner used in kiloWatt-hours.
Since most central air conditioners run on 220 volts, you won’t be able to use the Kill-A-Watt meter on one of these units because they have their own circuit breaker. The Emporia monitor can be used in this situation.
You’ll need an electrician to install these devices, however, because they use clamp-on sensors and must be mounted on your breaker box.
On this page, you’ll find videos that explain the process in further detail: determining the cooling system’s power usage
The next step is to determine the sort of batteries you’ll be using once you’ve estimated or measured your air conditioner’s energy usage.
Depending on the type of battery you use, the size and lifespan of your battery bank will be affected.
Different battery chemistries and their recommended Depth Of Discharge (DOD)
A battery’s Depth Of Discharge (DOD) is the proportion of its overall capacity that has been depleted. In other words, a battery that has been depleted to 30% of its capacity is considered to be 70% DOD. Using the same battery, it would have a 30% charge remaining (or SOC).
The capacity of a battery is directly correlated to its DOD. The more a battery is discharged, the faster it degrades.
Consider a battery that loses 60% of its capacity after 1500 cycles of charging and discharging since it is only 30% depleted on a regular basis (30% DOD/70% SOC). It would lose 60% of its capacity after only 300 cycles if the same battery was discharged 100% of the time (100%)
A battery bank’s capacity isn’t as important as its useable capacity, which is determined by the recommended depth of discharge, which in turn affects the battery’s lifespan. But the “usable capacity” of each battery type varies.
Lead-Acid and lithium batteries are two of the most common battery kinds on the market.
The following elements are found in this battery’s chemistry:
- Lead-acid (SLA) batteries that are completely sealed
- batteries that have been flooded with lead-acid
- Batteries with a Glass Mat (AGM) technology
Generally speaking, these batteries’ recommended depth of discharge (DOD) is 50%. One of these batteries can be used for as many as 500 cycles with a 50% DOD, however this depends on the battery itself.
It is generally accepted that the DOD of 50% will extend the life of a deep cycle lead-acid battery by about 1000 cycles, or about three years if the battery is charged and discharged once a day.
Because lead-acid batteries have a capacity of 200Ah at 12 volts, if you require a battery bank to supply 100Ah of energy, you’ll need 200Ah of capacity at 12 volts.
Lithium Iron Phosphate is the most prevalent lithium-based battery technology on the market (LFP or LiFePo4).
These batteries are often more expensive than lead-acid batteries. When it comes to batteries, lithium is the most common, lasting up to 6000 cycles at a 50% DOD. These batteries can still last up to 4000 cycles when discharged to an 80 percent depth of drain, as recommended by the manufacturers.
So if you’re using a lithium battery bank, you’ll need a 12V-125Ah lithium battery bank if you want it to deliver 100Ah (at 12V) every day and endure about 10 years.
Now that we’ve covered the fundamentals, the following step is to figure out how big our battery bank should be.
How many 12 volt batteries to run an air conditioner?
There is a difference between watt-hours and kilowatt-hours (or kiloWatt-hours).
To figure out how many 12 volt batteries you’ll need, divide your air conditioner’s power usage (in Wh) by 12, and then multiply the result by the batteries’ maximum depth of discharge.
You can then divide the final value by the individual battery capacity.
A 5000 BTU air conditioner that operates for 8 hours a day and consumes 2400 Watt-hours on average is an example of a typical air conditioner. At 12 Volts, we can figure out the battery bank’s capacity assuming it will be powered by Lithium batteries.
It’s important to remember that the battery bank’s capacity is equal to the sum of its energy consumption and its voltage, which is expressed in a formula like this: ( percent )
capacity of battery bank (Ah @ 12V) = 2400 Wh divided by 12
(Ah @ 12V) = (2400 Wh 12) 0.8 Battery Bank Capacity
250 Amp-hours of battery bank capacity at 12 volts (Ah @ 12V)
As a general rule of thumb, this quantity should be rounded up to 300 Amp-hours at 12 Volts in order to account for system losses.
3 of these 12V-100Ah Ampere Time batteries would be the most cost-effective option for this battery bank. Three of these 12V-100Ah Battle Born batteries would be an excellent high-end option to consider.
How Many Batteries Do I Need to Run an RV Air Conditioner?
It all relies on the type of battery you have if you want to power your RV air conditioner using battery power.
Flooded Cell Batteries
Batteries with flooded cells (those into which water is poured) provide the fewest amp hours (AH). This battery can only be used down to half of its capacity. In the long run, this will cause the battery to lose its ability to recharge. As a result, even if a 12 volt flooded cell battery is stated to have 100 AH of power, you are only getting 50 AH of actual usable power from such a battery..
A common six-volt goft cart battery (of the flooded cell sort) has an amp hour capacity of 200 to 400. However, they all have the same discharge restrictions. It’s generally a bad idea to discharge below 50% of your battery’s capacity.
AGM batteries have a low self-discharge limit of 20%. As a result, a 100 amp hour AGM battery can provide up to 80 amp hours of useable power. That means that the air conditioner will run for a longer period of time.
In order to power the air conditioner, how many AGM batteries do you need to purchase? Even so, four people are required to keep it running for an hour, and it may go as long as an hour and a half.
Lithium Phosphate Batteries
Among the most popular lithium phosphate battery manufacturers for usage in recreational vehicles are Battleborn, Relion, and Renogy. The majority of these are available in 100 AH configurations. Batteries of this type can be completely depleted to zero without causing any harm to them. This means that the air conditioner will run longer.
At the most, you’ll be able to run your air conditioner for two hours on four lithium batteries.
Compared to lead-acid batteries, lithium batteries are significantly lighter in weight. In a trailer or RV, you can fit more of these batteries than you can with heavier flooded cell or AGM batteries.
Tesla Battery Modules
It’s only recently that people are considering the notion of putting secondhand Tesla battery modules in their RV. Lithium Ion batteries, rather than Lithium Phosphate, are used in these devices. The battery pack in a normal Tesla vehicle contains 16 modules. Only one of these modules operates at 24 volts as opposed to 12 or 6 and provides 200 to 220 AH in normal configurations. A single Tesla module provides the same amount of power as four lithium phosphate batteries from Battleborn, Relion, or Renogy, but at a fraction of the price.
Using just one Tesla battery module, an RV air conditioner can run for nearly three hours.
Tesla automobile batteries are installed in RVs by a mobile RV specialist.
How Many Batteries Do I Need for 8 hours?
Battery power is essential for long-term ‘off-grid’ camping. When running an RV air conditioner for 8 hours, how many batteries are required?
Flooded Cell Batteries – These 12 volt, 100 AH batteries typically come in packs of 20 to 24. Cargo capacity should be roughly 2,000 pounds, and it should be either over the trailer wheels or between motorhome tires. This means you’ll need between 12 and 14 six-volt batteries with a 200-ampere hour capacity. Because these are heftier batteries, you should expect a similar overall weight.
Get between 14 and 18 of these batteries in the 100-AH variety and roughly 8 to 12 in the 6-volt 150-AH variety for your AGM battery pack. Expect a similar amount of strain in terms of body weight.
Lithium Phosphate Batteries – These 12 volt, 100 AH batteries are available in quantities ranging from 12 to 16. As a result, you should expect to add an additional 600-800 pounds of cargo weight to your rig with these new batteries.
To run an air conditioner for eight hours, you’ll need to buy three Tesla battery modules. Considering that each module typically weighs 60 pounds, you can expect to add about 180 pounds of cargo to your order.
Where Can I Buy Tesla Battery Modules?
There are several internet stores that sell these, but they’re not easy to come by. Just type in “where to buy Tesla battery modules” into Google and you’ll find plenty of results. Contact “The BoonDoctor,” an RV specialist who specializes in installing Tesla battery modules into recreational vehicles, for help.
Can I Run My RV Air Conditioner on Battery Power?
These days, most RVs come with a 15,000 BTU air conditioning unit. Just to get them going, each of these machines needs at least 3,500 watts. Then, it needs around 1,500 watts to run that device.
To make use of your battery power, you’ll need an inverter with a minimum output of 4,000 watts of DC-to-AC power. An inverter of that size is uncommon in recreational vehicles. In most cases, there is no inverter at all included in the RV. A 1,000- to 2,000-watt inverter is standard on those that have one.
To reduce the required beginning watts, consider installing a “soft start” on your air conditioner. To put it another way, if you have a 15,000 BTU AC unit, you may only need 1,500 to 2,000 watts of power to get it up and running.
A power inverter is only found in higher-end recreational vehicles. Class A motorhomes, fifth-wheel trailers, and higher-end Class B vans tend to fall into this category. Two to three air conditioners are standard in most Class A and fifth-wheel trailers. As a result, a higher-wattage power inverter, maybe as high as 7,000 watts, is required to run all two or three air conditioners. That high of an inverter is not available in any RV or motorhome.
How Many Batteries Would I Need?
One hour of air conditioning using three 100 AH (amp hour) Lithium Phosphate batteries would be enough to cool two 15,000 BTU air conditioners. You’ll need 1,500 watts of solar panels on the roof to offset that need for electricity. This must be a sunny summer day in the middle of summer, with a lot of overhead sunlight.
Think about how much power you’ll need if you want to run two air conditioners for an hour on that system. Consider how much energy is required to run a single air conditioner for eight hours.
See “How Much Battery Power Will I Need for Boondocking?” for more information.
Why Lithium Phosphate Batteries?
Without causing any harm, Lithium Phosphate batteries can be completely depleted. These batteries may be pulled down to less than half of their capacity compared to flooded-cell batteries or even AGM batteries, which can only be used at half capacity.
You’ll need a lot of batteries to run an air conditioner for 8 hours on battery power. 50 pounds is the weight of a common 12-volt flooded-cell battery, which delivers 100 AH. Lithium batteries often weigh around 30 pounds when they’re fully charged. To power two air conditioners for eight hours, you may require 16 to 20 flooded-cell, 12 volt, 100 AH batteries. As a result, it may weigh up to 1,000 pounds and take up considerable room. In comparison, you’ll require eight 100 AH lithium batteries weighing a total of 240 lbs. That’s a significant variation.
Cargo capacity in most trailers is limited, whether they’re bumper-pull or fifth-wheel types. Toy haulers cost a lot of money, and it doesn’t even take into account the weight of your other belongings (clothes, appliances, tools, electronics, etc.)
It’s an Extremely Expensive System
About $1,000.00 per is the price for a standard 12 volt, 100 AH lithium phosphate battery. That works up to around $8,000 worth of batteries to power two air conditioners for eight hours.
If you don’t have a $1,200 to $2,000 power inverter, that doesn’t take into account the cost of installing it. The 1,500 to 2,000 watts of solar panels on your roof to recharge those batteries while running your air conditioning are also not included in this calculation This is going to cost between $1,500.00 and $2,000.00.
In order to power two air conditioning units for only eight hours a day, you’re looking at paying $11,000.00 to $12,000.000 dollars on additional components (copper wire, battery monitor, 2-way or 3-way transfer switch, solar panel mounting hardware, etc.).
That is, of course, if you have a sunny day to replenish your batteries.
Using Tesla auto batteries can help you save money on your battery costs. For a fraction of the price, Tesla batteries can provide more power. In addition, a converter will be needed to bring the final output down to 12 volts from a 24 volt system. Tesla battery banks may be installed on RVs by a mobile RV specialist.
So Why Bother With Solar Panels and Lithium Batteries?
Light-duty electrical needs, such as lights, fans, water pump, power awning, and power tongue jack are typically powered by solar panels and lithium batteries. These supply all the electricity you’ll need to camp out for weeks at a time without running out.
Air conditioning is not a need for most boondockers, who prefer to camp in cooler climates. That example, during the summer, people camp at higher elevations to avoid the oppressive heat.
In most cases, a boondocker only uses AC power for small appliances like a blender, C-PAP machine, or television. Battery power inverters of 500 to 1,000 watts can be used to power these devices. A small battery bank of 200 to 300 Ah and a solar panel array of 400 to 800 W are also presupposed.
RVers who spend the majority of their time boondocking can still afford solar electricity when paired with a sufficient battery bank and a modest to medium-sized power converter.
Learn how many solar panels you need for boondocking in our previous post, “How Many Solar Panels Do I Need?”
If You Need Air Conditioning, Get a Generator
Generators are designed to handle situations like these. Air conditioners and microwave ovens, which demand a lot of power, can be powered by these. Generators can cost a lot of money up front, not to mention the additional costs associated with running them for extended periods of time. However, if you plan to use a lot of electricity when boondocking, this is the most cost-effective option.
Please check out our other posts about generators, “Do I Need a Generator for Boondocking?” and “How Big of a Generator Do I Need?”
How many batteries do I need for a 5000 BTU air conditioner?
At the very least, you’ll need to have at least 600 watts of solar power, a 40-amp MPPT charge controller, a 2000-watt pure sine wave inverter, and 400- or 800-amp-hour lithium ion batteries to power a 5000 BTU air conditioning unit on solar power alone. The A/C will run for around eight hours with this setup.
Can an inverter run an air conditioner?
A 12-volt battery can power a 120-volt load with an inverter. To summarize, your inverter and batteries may be able to start and run a modern efficient air conditioner, but not for a long period of time. Your 600-amp-hour bank is only capable of supplying 400 amps of power with any efficiency.
Does a 5000 BTU air conditioner use a lot of electricity?

It’s enough to know that it’s got 5,000 BTUs and is properly proportioned for your room/space in order to lower the temperature. Running a 5,000 BTU air conditioner at full capacity consumes 500W of electricity.
How many hours should AC run per day?
How Many Hours a Day Should You Use Your Air Conditioner? On a hot or humid day, an air conditioner should run for roughly 15 to 20 minutes. The inside temperature should be set to your preference after around 20 minutes, at which point the unit will shut off automatically.
Is it bad to start your car with AC on?
Basically, the answer is no! Starting your car when the AC is running is not dangerous. The car will automatically cut down its electricity when the engine is turned off. Essentially, this implies that as soon as you turn on the car’s engine, all the car’s systems will be shut down.
How big of an inverter do I need to run an air conditioner?
An air conditioner that draws five amps of AC current at 120 volts would need 600 watt-hours of power. This little air conditioner requires at least a 3,000 watt, 120-volt converter to work at full power, which is five times the starting wattage demand.
Do portable air conditioners use a lot of electricity?
How Much Power Is Consumed By A Portable AC Unit? An average of 2900 watts per hour is used by mid-sized portable air conditioners. Even central air conditioners use less electricity than some of the largest units, which can use up to 4100 watts per hour.
What size inverter do I need to run a 8000 BTU air conditioner?

Cooling Things Up!
Wow! You know how many 12 volt batteries are needed to power an air conditioner. About an hour’s worth of air conditioning can be powered by a single battery.
Using flooded batteries, you can run a 20-24 V AC at 12 V or a 12-14 V AC at 6 V. The batteries are also AGM. Using 12 V, they can run an AC between 14-18 volts and 8-12 volts, respectively.
Lithium phosphate batteries, on the other hand, require between 12 and 16 at 6 V to power the same AC. In addition, an air cooling system powered by three Tesla batteries is available. Would you like to find out more?
