Battery Testing Battery electrolyte is acidichandle with careIf electrolyte contacts any part of the body, immediately flush
charging the batteryThis test can only be used when there is sufficient electrolyte above the battery plates to fill the
hydrometer tubeDo not, however, take readings immediately after refilling the cells with waterThe battery must be charged,
then check with hydrometerView the hydrometer with your eye on the same level with the liquid surfaceThe float of the hydrometer
must be freeMake correction for the temperatureSpecific gravity will vary points (0.004) with every 1QF (6C) temperature
changeFor each 10F (6C) below 80F (2JOC), subtract points from hydrometer readingFor each 10F (6C) above 80F (27C), add points
to hydrometer readingAfter correcting to 80F (2JOC), interpret readings as followsAll cell readings uniform and above 1.225
specific gravity indicates battery is serviceable, but may require charging All cell readings uniform and below 1.225 specific
