The RV Doctor, Gary Bunzer, tells us tips on how to keep RV batteries in good condition.
•If you stay in camp grounds a lot or leave the couch plugged in during periods of non-use, one of the things you need to know is the boiling out the electrolyte on the auxiliary battery.
•So you need to check the electrolyte periodically when the battery is charging so that it do not dry out.
•If you find it dry, put in some distilled water and then check for any other problems.
This sure is an useful and important tip to remember!
