Top 5 RV Batteries for Dry Camping


Dry camping, also known as boondocking is a wonderful way to withdraw from the modern world and reconnect with nature. It is critical to find the best RV battery for dry camping that can deliver adequate power for your needs if you decide to go off the grid because you don’t want to leave yourself without electrical power out there. There are a few battery types you can choose from to make sure you have power no matter where you are.

Types Of RV Batteries

12-volt Battery

12-Volt batteries are normally less expensive than 6-Volt batteries, but they don’t last as long and can’t be drained and recharged as frequently as 6-Volt batteries. 12-volt batteries are good for folks who plan to use connections frequently, but they aren’t the ideal choice for lengthy boondocking journeys.

6-volt Battery

Many dry campers prefer 6-Volt batteries because they are very affordable and have a longer lifespan than 12-Volt batteries. You may even connect multiple of these in series to get even more amp-hours out of your battery management system.

Lead-Acid Deep Cycle Battery

This is the most typical RV battery, which is made up of lead plates immersed in a sulfuric acid and water-electrolyte solution. They’re available in 6- and 12-volt versions. The quantity of charge a battery can hold is determined by the size of the lead plates and the volume of electrolyte solution. Make sure your RV’s battery has a deep-cycle battery, which can drain more thoroughly than ordinary lead-acid batteries.

Lithium-Ion Batteries

You may probably already have Lithium-ion batteries in your phone and laptop. They’re smaller and lighter than lead-acid batteries, and they’re newer. The lithium battery doesn’t require as much maintenance as lead-acid batteries and can lose their charge fully without causing damage to the battery. For RVs, they nearly always come in 12-Volt configurations. Lithium-Ion batteries, on the other hand, are significantly more costly than lead-acid batteries.

Absorbent Glass Mat (AGM) Batteries

AGM batteries are similar to lead-acid batteries, except instead of lead plates, they employ a mat of glass fibers. They drain faster than lead-acid batteries, but most owners don’t think the price difference is worth it. However, unlike lead-acid batteries, they are maintenance-free.
