Cleaning
Keep the batteries dry and clean. Contamination and
oxide on the batteries and battery poles can cause
stray currents, voltage drop and discharge, especi-
ally in wet weather. Clean oxidation from the battery
poles and terminals, using a copper brush. Tighten
the terminals securely and grease them with terminal
grease or Vaseline.
Electrolyte level
The electrolyte level should be 5–10 mm (0.2–0.4”)
above the cell plates in the battery. Top up with batte-
ry water as necessary. After topping up, the batteries
should be charged by connecting them to a battery
charger, or by running the engine at normal speed for
30 minutes.

Some maintenance-free batteries have spe-
cial instructions, which must be observed.
