1Visual Inspection The first step in determining the condition of battery should be visual inspectionLook for conditions
after refilling the cells with waterThe battery must be charged, then checked with hydrometerView the hydrometer with your
eye on the same level with the liquid surfaceThe float of the hydrometer must be free Make correction for the temperature
Specific gravity will vary points (0.004) with every 10F (6C) temperature changeFor each 10F (6C) below 80F (2rC)' subtract
points from hydrometer readingFor each 1QF (6C) above 80F (2rC), add points to hydrometer readingAfter correcting to 80F
(2rC), interpret readings as follows: All 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 gravitycharge fully and retest Variation of more
than 30 points (0.030) specific gravity between any two cells indicates battery condition is questionableRecharge and retest
