Batteries
a. Clean batteries, trays, supports, and retainers (see WP 0153 00).
b. If supports, trays, and/or retainers are corroded, paint with
acid-resistant paint.
NOTE
Batteries are in good condition and serviceable
when the specific gravity readings are between
1.250 and 1.300 corrected to 80 F (27 C) (1.200
to 1.225 for batteries used in tropical climates)
and the specific gravity between individual cells
does not vary by more than 0.040.
c. Test specific gravity of battery electrolyte. Specific gravity shall
be a minimum of 1.225 under normal operating conditions and 1.180
under tropical conditions (refer to TM 9-6140-200-14). If specific
gravity is unsatisfactory, charge or replace batteries (see WP 0153
00).
