8. PREPARING THE BATTERY CHARGER
8.1 BEFORE CHARGING YOUR
BATTERY
We recommend that the battery is disconnected
from the vehicle, this will avoid any possible
damage to the alternator. Loss of codes for audio
and security etc, can be prevented by connecting a
Draper Memory Saver – Stock No. 22277 12V
socket type (Fig.1), or Stock No. 22231 EOBD
16pin diagnostic socket type (Fig.2) before
disconnecting the battery. Check that the voltage of
the battery matches that of the charger.
Before connecting the battery to the charger ensure
that both are stable and on a level surface. If the
battery has cell filler caps, loosen or remove them to
aid in the escape of charging gasses (if the battery
is a Gel or maintenance free/sealed type, please
refer to battery manufacturers published charging
advice). Once the cell caps have been loosened or
removed it is advisable to check the level of
electrolyte in each cell and top up with distilled
water only to the recommended fill level.
Caution! Never top up your battery with tap water.
Maintenance free batteries
(low maintenance batteries)
These batteries often have cells with no filler caps
and therefore cannot be topped up with distilled
water, it is important that during the charging they are not allowed to “gas” because this will reduce
the level of electrolyte which cannot be replaced. You should take extra care when the battery
reaches “full” during charging and do not use the “fast” charge option on such batteries.
