During boost-charging, the charging current should not exceed 40 A. Max. charge time 1.5 hours.
IMPORTANT
Do not boost-charge a battery if the voltage is below 12 V or if the battery is more than two years old.
3. If the battery has been run flat, because a lamp or other consumer was left on, a weak starting charge is required to initiate the chemical process in
the battery. In such cases, start with a charge current of about 3 A (it must not exceed 5 A) for 24 hours or until the charge current has fallen to its
lowest steady value.
The battery begins to give off gas at 14.4 V.
In the above case, a battery charger with a pulsating charging current should be used for preference.
