200 Car care and technical information
Tap water contains salts and minerals that
accelerate the corrosion of the battery elec-
trodes, which can shorten the life of the bat-
tery.
The specific gravity of the electrolyte when
the battery is fully charged is 1.28. A specific
gravity of 1.18 roughly indicates a 50%
charge (see also page 254).
If frequent short journeys are made, the bat-
tery 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 run.
A car with a standard equipment specifica-
tion 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 fit-
ted, such as a car phone, the charge may
only be sufficient for about 15 days.
NOTE
Never use tap water to top up the battery.
NOTE
A discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.
