Checking electrolyte level
For conventional batteries it is required
to check the electrolyte level regularly.
Remove vent caps (taking care no spark
or open flame is nearby) and inspect the
level. Fluid should be 10 to 15 mm (3/8" to
5/8") above top of all plates. If necessary
top up with distilled water. Replace vent
caps and charge the battery for 15 min-
utes at 15 - 25 Amps to mix electrolyte.

Checking specific gravity
Measure the electrolyte specific gravity
of the individual cells with a commer-
cial hydrometer. The hydrometer reading
(see table) indicates the state of charge.
Hydrometer reading of all cells should be
at least 1.200 and show less than 0.050
between high and low. If not, recharge
or replace battery. During checking the
temperature of the electrolyte should pref-
erably be 20°C (68°F).
