You may hear AGM batteries referred to as sealed lead-acid (SLA) or valve-regulated (VRLA).

Sealed Lead-Acid (AGM)ĪGM batteries are a type of lead-acid battery, but the internal construction has been improved. Only used distilled water!įlooded batteries are also known as “wet” batteries. These batteries can lose water in their cells due to overcharging or evaporation, so they should be checked manually. Meet Old Faithful: The simple flooded lead-acid battery. Modern campers have one of three types of batteries. However, if you venture forth into the boondocks, you’ll appreciate the additional energy capacity of a true deep-cycle battery. If you dwell mostly in developed campgrounds, you won’t suffer if you use marine batteries. Lots of RVers use marine “deep-cycle” batteries. They can both turn over a small engine and power your lights, but they don’t do either to the best of their ability. They offer limited discharge capacity in exchange for higher cranking amps. Marine batteries are a jack-of-all-trades. However, they shouldn’t be quickly discharged. Because they are dedicated to one thing, they’re very good at it. However, the intestines of a true deep-cycle battery aren’t quite the same as a marine-style battery.ĭeep-cycle batteries are dedicated to getting the most energy capacity out of your battery. Both are capable of being discharged and recharged.Despite what your RV salesman may tell you, no, marine batteries and RV deep-cycle batteries are not the same! They do share some similarities:
