Best RV Battery
WindyNation 12 Volt AGM
This WindyNation 12 volt AGM 100AH deep cycle battery is our top choice for the best overall RV battery. It’s an absorbed glass mat (AGM), 100AH (amp-hours) battery that is maintenance-free and doesn’t require watering service like the traditional wet cell batteries.
These sealed, non-spillable batteries are manufactured using 99.995 percent pure lead, which results in a very low self-discharge rate. Lower-quality batteries made with recycled lead can negatively affect battery life and performance.
WindyNation 12 volt AGM batteries are specially designed to provide off-grid power. These batteries boast long battery life and maximal power storage capacity to keep your lights on, devices charged, and everything running smoothly. Read my full WindyNation 12 Volt AGM battery review for more.

Buying a New Travel Trailer or RV Battery: What to Look For
Battery shopping can be intimidating. You want the most for your money, but you need to know you’re making the right choice and getting a safe battery that’s made for your RV or travel trailer and is powerful enough to meet your needs. Some things to keep in mind when shopping around are:
- Endurance and power
- Amp-hours and reserve capacity
- Wet cell versus absorbed glass mat
- Budget and applications
Endurance and Power
Starter batteries expel short bursts of high power to get things up and running. travel trailer batteries, or deep cycle batteries, expel steady, consistent power over longer periods of time. These batteries keep the lights on and charge and power devices and appliances long after your RV calls it a day. A quality deep cycle battery should last longer than a starter battery, so you won’t need to replace it often.
Amp-Hours and Reserve Capacity
You don’t have to be an engineer to buy a good battery, but knowing what you want and need is a must for just about any purchase, especially when it pertains to your home on wheels. Use the “more is better” approach when comparing amp-hours and reserve capacities: The higher the number, the longer and more powerful the battery. For the amp-hours approach, a 100AH battery will last longer than a 35AH battery.
If you opt to go by the reserve capacity as opposed to amp-hours, a 120-minute reserve capacity is better than a 75-minute reserve capacity. However, you must stick with one or the other; you can’t realistically compare one battery’s amp-hours to another battery’s reserve capacity.
The depth of discharge (DoD) is the percentage of the battery that has been discharged relative to the overall power capacity of the battery. The more often a battery is charged and discharged, the shorter its lifespan will be, so make sure to check with the battery manufacturer to get the maximum recommended DoD to keep the battery in good shape.
Wet Cell Versus Absorbed Glass Mat (AGM) Batteries
Wet cell or “flooded” batteries and absorbed glass mat batteries are the two major types of deep cycle batteries. It really boils down to maintenance and maintenance-free configurations. Wet cell batteries require occasional refilling because they lose the water and acid solution with each use.
Some wet cell batteries require professional maintenance service while others can be refilled by users; kind of like non-removable cell phone batteries that must be sent in to be serviced or changed. Spillage or leakage can be toxic and dangerous, which makes wet cells a bit more intimidating. They are not ideal or resistant to extreme weather conditions like AGM or gel pack batteries.
AGM batteries are sealed, spill-proof, and non-hazardous and do not require maintenance. These batteries are designed for water and mobility applications, but come in handy for those who aren’t mechanically inclined or don’t want the added concern and stress of recreational vehicle maintenance.
The recharging process for AGM batteries is much faster than wet cell batteries, but they offer less protection and are overall more prone to damage and decreased performance over time. Undercharging and overcharging can shorten battery life or cause permanent damage, so there’s a learning curve with these types of batteries that one must remain aware of.
Budget and Applications
When buying an RV battery, it is essential to know what you will be using it for and how much you can spend. These batteries control, charge, and use energy for all sorts of applications such as lighting, appliances, chargeable devices, and temperature control.
The most expensive battery does not always mean the best battery, just like the least expensive doesn’t mean the worst. Know from the start what you are prepared to spend and how much power you need.

Frequently Asked Questions
What Battery Type Is Best For My Travel Trailer?
We recommend deep cycle batteries for travel trailers. Because they deliver sustained power over longer periods of time they are more useful for a trailer than your regular car battery and will provide more efficient and reliable power while not drawing as much current as a regular car battery. Paired with solar panes they can help deliver tons of power to your trailer.
How Many Batteries Do I Need For My Trailer?
Depending on how big your trailer is you might need up to 6 or 7 batteries to run all of your systems. Smaller trailers require at least two to be able to power all of your creature comforts. You can daisy chain batteries together to give you a larger cell that will deliver more effective and reliable power.
How Long Do RV Batteries Last?
If taken care of properly (including not overcharging), your batteries should last you between 5 and 7 years. Deep cycle batteries are designed to be ran down and recharged many times over and with regular maintenance and no overuse, they should be able to power your trailer for many years to come. Read Brian’s guide on RV battery life expectancy for more.
How Long Should You Charge A Deep Cycle Battery?
The length of charging for deep cycle batteries depends on how many amps your charger is. A standard 15-amp charger should top off a battery in about two hours. Lower amperage chargers will require a much longer amount of time, so double check your charger before charging your battery to see how many amps it can push.
