To make sure that the batteries are always ready for use, periodically check and charge as necessary . Check batteries at least every two weeks in freezing weather; at least every four weeks in warmer weather. A fully-charged battery will not freeze under normal circumstances , so it is imperative that the batteries remain charged during winter. A safe level of charge is a specif ic gravity reading of 1 .225 to 1 .280. Alway s use a battery hydrometer which has a temperature correction scale. It is advisable to have the coach shoreline connected to the 120 volt ac supply so that the batteries rema in fully charged. A dirty battery may eventually dissipate its charge through conductive surface contamination . Clean battery top surface with a damp cloth and dry thoroughly. Check that battery terminals and associated battery jumer terminals are tight and free of corrosion. To clean terminals, neutralize corrosive deposits with a solution of baking soda, rinse with clear water , and dry. Note that commercial type spray-on battery cleaners are available at automotive supply stores. Use as directed to keep the batteries clean. Spray-on cable and terminal protective coatings are also available, easy to use, and effective. | To make sure that the batteries are always ready for use, periodically check and charge as necessary .
