"We make it simple"

The battery that supplies 12 volts to your RV is also called the house battery, and you might have more than one. This type of deep cycle battery powers the home appliances in your RV, like your microwave, refrigerator, and TV.

  • It is designed for deep cycles, with thick plates frequently discharged and recharged.
  • It is rated in Amp Hours (AH) or Reserve Capacity (RC) instead of CCA.
  • It provides a steady current over long durations.

If you have a towable RV, you only need to keep up with the 12-volt battery. It is important to ensure your battery operates so your smoke and carbon monoxide detectors function.

The Chassis Battery

Also called the starter battery, this is the battery used to run your drivable RV’s engine. It starts the RV’s auto component using large currents over short periods. Your chassis battery has the following properties:

  • It has several thin plates to maximize the area exposed to the electrolyte.
  • It is rated in Cold Cranking Amps (CCA).
  • It is unable to perform deep cycle applications.

Change from 6 Volt Flooded Battery to 6 Volt Agm Battery

Before Flooded Batteries

With flooded batteries, you have to worry about the corrosion build-up and check the water every month to maintain battery life.

After with AGM Batteries

With the AGM battery, there are no worries about checking the water. The shelf life is longer, the recharge is faster, and it has a longer life span.
