Checking the Battery Terminals

When the Battery Goes Flat
1. Check the specific gravity of the
battery fluid using a hydrometer. If
the specific gravity is too low, the
battery should be charged.
Specific gravity at a fluid temperature of
20°C (68°F)
1.27 - 1.29
1. Check the terminals for looseness
and corrosion.
2. If a terminal is found to be corroded
and coated in white powder, wash
this away with warm water and then
wipe fully dry. Excessively corroded
terminals should be polished using a
wire brush or sandpaper.
3. When you have finished cleaning the
terminals, apply a thin layer of grease
and securely connect the battery
cables, taking care to ensure that they
are tight.
See "If the Battery Runs Flat"
regarding steps to be taken should
the battery be completely discharged.
