178 Car care
The charge level should be checked with a
battery-acid tester. The specific gravity of
the acid in a fully charged battery should be
1.28. A specific gravity of 1.18 roughly indi-
cates a 50% charge.
If frequent short journeys are made in cold
weather, the battery may need to be given a
booster charge. This can be done either
using a battery charger or by taking the car
for a long drive.
A car with standard equipment and a fully
charged battery can be left for up to 40 days
and still have a sufficient charge for starting.
If extra equipment is fitted, such as a mobile
telephone, the time may be reduced to
about 15 days.
Always connect the positive (red) cable to
the positive (+) terminal of the battery and
the negative (blue) cable to its negative (-)
terminal. Always disconnect both battery
leads when boost charging the battery.
NOTE
A discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.
NOTE
• Don’t connect the battery terminals
+ and – the wrong way around.
• Serious damage can occur to the car’s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
