Finally, it protects your RV batteries from excessive drain – even when your appliances are off, they’re still draining your batteries a little bit.

How to maintain RV batteries?

3. RV Battery Maintenance 1 Maintain electrolyte levels in flooded-cell batteries. Over time, flooded-cell batteries lose water with each charge cycle, and this water needs to be replenished. You must use distilled water to help reduce the chance of sulfation, or the formation of sulfate crystals that can occur when the battery plates are exposed to air. Check the batteries at least once per month, and ensure that they’re fully charged before performing the necessary maintenance. 2 Clean battery terminals to remove any corrosion that has built up. You can use a mixture of one cup of baking soda to a gallon of water or a commercial battery contact cleaning product, and utilize a toothbrush for scrubbing. 3 Allowing your batteries to get too low in charge can also increase sulfation. When your batteries fall below 80%, or 12.4 volts, sulfation can begin. Thus, always recharge your batteries in a timely manner after using them. 4 Try to recharge your batteries often. For example, if you discharge your battery to 50% every day, it’ll last twice as long as if you’d discharged it to 20% each day. However, also keep in mind that overcharging and hot temperatures also have negative effects on batteries over time.

How does a deep cycle battery compare to a car battery?

It’s a lot like a car battery and uses the same chemistry to create and retain power, but a deep-cycle battery produces a steady amount of current over a longer period of time, whereas car batteries create a lot of current over a short period of time (since they then charge while you’re driving anyway).

How long do lithium batteries last?

Lithium batteries also have a much longer lifespan than other battery types, and are typically rated for 5,000 cycles — as opposed to the 400 or so cycles most lead-acid batteries get.
