Maintenance and Care
Cleaning
Keep batteries dry and clean. Oxidation or dirt on the
battery and battery terminals can cause short-circuits,
voltage drop and discharge, especially in damp weather.
Clean the battery terminals and leads to remove oxidation
using a brass brush. Tighten the cable terminals well and
grease them with terminal grease or petroleum jelly.
Electrolyte Level
The electrolyte should be 5 - 10 mm over the plates in the
battery. Top up using
distilled water if necessary. After
topping up charge the battery for at least 30 minutes by
running the engine at fast idle.
NOTE! Certain maintenance-free batteries have special
instructions which must be followed.
Caution!
Never mix up battery positive and negative
terminals.
Battery: Charging
DANGER!
Explosion Hazard! The batteries give off hydrogen
gas during charging which, when mixed with air,
can form an explosive gas - oxyhydrogen. A
short-circuit, naked flame, or spark can cause a
large explosion. Ensure that the area in which you
are working is well ventilated.
WARNING!
The battery electrolyte contains extremely
corrosive sulfuric acid. Protect your skin and
clothes when charging or handling batteries.
Always use protective goggles and gloves. If
battery electrolyte comes into contact with
unprotected skin wash off immediately using
plenty of water and soap. If battery acid comes
into contact with the eyes, flush immediately with
plenty of water and obtain medical assistance
without delay.
