CAUTION
Do not use ahigh rate battery charger, as il typically employed at automotiVe servicestetlont:, unless the charger rate can be reduced to the level requiredCharging the battery at rate higher than specified may ruin the batteryCharging at high rate causes excess heat which can warp the p.lates and cause Intemal shortingHigher-than normal cherging rates also cause the plates to shed active materialDeposits will accumulate, and can cause internal shortingIf the temlperalure of the electrolyte rises above 4SC (11SF) during charging, reduce the charging rate to lowe.r the, temperature, and Increaae charging time proportionately
Tum the charger off, then disc,onnect it from the battery Check battery voltageBattery voltage should be 1213 Check the specific gravity of each ce'" with hydrometer (see Battery Condition) If the voltmeter or hydrometer readings are below those specified, additional charging is necessary before the battery can be installed
