BATTERY TESTING (Sheet 3 of 5)

Testing Using Hydrometer (Sheet 2 of 2)

8.

Using correction chart (G), correct

readings recorded in step 6 to 80°F.

Example: Hydrometer shows 1.280

specific gravity.

Electrolyte temperature

is 0°F. Using correction chart (G),

note that for electrolyte temperature

of 0°F, 0.032 is to be subtracted from

hydrometer reading.

Therefore, corrected

reading is:

1.280-0.032 = 1.248.

9.

Using pencil and paper, add all six corrected

readings together and divide by 6 to

find the average reading for the battery.

10.

If average reading for battery is below

1.225, charge battery (TM 5-5420-202-10).

11.

If any two of six readings for battery are not

within 0.025 of each other, replace battery

(page 10-253).

12.

Replace rubber battery cover (page 10-256).

13.

Turn MASTER BATTERY switch to ON (TM

5-5420-202-10).
