HOW TO: Maintain & Equalize RV Batteries

 

We demonstrate how to properly service, maintain and equalize the 6-volt deep-cycle golf cart batteries in an RV.

The “house” batteries are one of the most misunderstood systems on any RV. The proper care and maintenance of your battery bank will help it perform better and last longer.

Flooded, lead-acid batteries are the most common type of battery used in an RV. Keeping them clean and the water level correct should be part of your routine maintenance.

During the normal operating process, the batteries discharge and re-charge over and over again. This can cause sulfation, which is the process of sulfates in the electrolyte (acid) coming out of suspension (suspended in the liquid electrolyte) and attaching to the lead plates instead.

Equalizing the batteries solves this problem by “boiling” the batteries at higher voltage to break the sulfate loose from the lead plates, and putting it back into suspension, where it belongs.
