BATTERIES Wet cell batteries will give off gas as a natural result of charging and will experience some water loss. It is very important that the electrolyte level be checked frequently and topped off with distilled water when necessary. Follow the battery manufacturer’s recommendations for maintenance. Never allow the top of the battery plates to be exposed to air, as contamination of the cell will result. Keep the top of batteries clean. Always provide adequate ventilation for the battery stor

BATTERY CHARGING The equalizing charge is a timed, 8-hour cycle. The cycle can be ended early by inter- rupting the AC power to the charger at any time during the cycle. Equalizing should only be engaged after the batteries have been fully charged by a normal battery charging cycle. During this equalizing stage, the battery voltage will increase to the equalize voltage. This will cause the battery bank to gas profusely and will accomplish the following: 1. Removal of residual sulfate. Each time

BATTERY CHARGING WARNINGS 1. Do not equalize gel cell batteries. Check remote default settings. 2. Always monitor the equalize charge cycle. Provide proper ventilation for battery fumes. Do not allow any sparks during equalizing. If one or more cells begin to overflow, terminate the equalize cycle. 3. Check the battery electrolyte both before and after the equalizing charge. Do not expose the battery plates to air. Leave the battery caps on while equalizing. Top off after equalizing. 4. Remove a
