INITIAL CHARGING
Filling electrolyte
Remove the short sealed tube before filling electrolyte. Fill
battery with electrolyte (dilute sulfuric acid solution with acid
concentration of 35.0% by weight, having a specific gravity of
1.28 at 20 C/86 F) up to indicated UPPER LEVEL. Filling
electroltye should be always cooled below 20 C/86 F before
filing into battery Leave battery standing for half an hour
after filing. Add additional electrolyte if necessary.
Charge battery with current as described in the tables shown

Visually inspect the surface of the battery container. If any signs
of cracking or electrolyte leakage from the sides of the battery
have occurred, replace the battery with a new one.
If the battery terminals are found to be coated with rust or an
acidic white powdery substance, then this can be cleaned away
with sandpaper.
The charging time for a new battery is determined by the number
of months that have elapsed since the date of manufacture.
Near the end of charging period, adjust the specific gravity of
electrolyte to value specified. After charging, adjust the
electrolyte level to the UPPER LEVEL with DISTILLED WATER.
