CAUTION
Do not use high rale balleJy charger, as it typically employed at automotive service stations, unless lie charger rate can, be reduced to the level requiredCharging the battery at rale higher than specified may ruin lIeballeJyCharging at high rale causes excess heat which can warp lie plates and cause inlemal shortingHigher-llan normal charging rates also cause lie plaIHto shed active materialDeposlls will accumulate, and can cause Inlernal shorlingIf lie temperalUre of lie eleclrolyle rises above 45C (11S"F) during charging, reduce the charging rate to lower lie temperature, and Increase charging time proportionately
Turn the charger off, then disconnect it from the battery Check battery voltageBattery voltage should be 1213 Check the specific gravity of each cell with hydrometer (see Battery Condition)If the voltmeter or hydrometer readings are bel'ow those specified, additional charging is necessary before the battery can be installed
