Cleaning
Keep the batteries clean and dry. Contamination and
oxide on the batteries and battery poles can cause
stray currents, voltage drop and discharge, especially
in wet weather. Remove oxidation from the battery
poles and terminals, using a brass brush. Tighten the
terminals securely and grease them with terminal
grease or petroleum jelly.
Filling
The electrolyte level should be 5–10 mm (0.2– 0.4")
above the cell plates in the battery. Top up with distilled
water as required.
After filling, the battery should be charged for at least
30 minutes by running the engine at idle.
Some maintenance-free batteries have special
instructions, which must be followed.
