BatteriesPage 82R-380 DC SystemMR-380-03TESTINGSpecific GravityNote: The battery must be fully charged beforeperforming this test.The specific gravity of a cell is an indication of the actualstate of charge of the cell. A fully charged cell should havea reading of 1275 to 1300 (see the illustration below). Adischarged cell will read 1100. Ideally, all cells in a batterywill have the same reading. Any cells in a battery thatvary by more than 25 points may be an indication of abad or weak cell.Clean the battery. Refer to Cleaning section forinformation on cleaning the battery.Using part number 77-200-00 hydrometer or equivalentgraduated type hydrometer, test and record the specificgravity of each cell in the battery.Use the highest reading to compare to all other cells. Anycell or cells that are more than 25 points less than thehighest reading should be suspected as being a bad cell.If, after charging, none of the cells exceed a hydrometerreading of 1250 then there may be a fault in the chargingsystem. If the charging system checks OK then thebattery pack is no longer accepting a charge and shouldbe replaced.It may be possible to replace Individual cells in industrialbatteries. Contact the battery manufacturer for details.This section is one section of a complete servicemanual.
