Battery Electrolyte Specific Gravity Test.

TM 9-6140-200-14

b. Read indicator with your eye located approximately level with fluid. Note

reading.

NOTE

Readings taken while looking at the indicator from a

sharp angle are very inaccurate.

If a new or recharged battery shows a difference of

more than 0.025 specific gravity between cells, the

battery is defective

c. Test all cells of the battery and note readings. Allowable high -to- low

difference in readings between cells shall be 0.025 points maximum.

d. At 80 degrees Fahrenheit electrolyte temperature each cell of a fully charged

battery should read 1.280 maximum. At 80 degree Fahrenheit a battery is

discharged if it reads less than 1.220.
