1Visual Inspection The first step in determining the condition of battery should be visual inspectionLook for conditions
immediately 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 freeMake correction for the temperatureSpecific
gravity will vary points (0.004) with every 10F (6C) temperature changeFor each 1QF (6C) below 80F (2JDC), subtract points
from hydrometer readingFor each 10F (6C) above 80F (2JDC), add points to hydrometer readingAfter correcting to 80F (2JDC),
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 gravity; charge fully and retest Variation of
