Batteries and charging

General

The external charger (Fig. 45) has been designed to charge two 12 volt Dryfit Gel type batteries.

Safety features

The chargers have features which prevent hazards or accidents occurring as a result of connecting batteries the wrong way round, overheating caused by fault conditions, or attempting to charge wrong voltage batteries.

The majority of charger sizes are electrically double insulated and no earth connection is required. Some larger sizes may be electrically earthed and this will be clearly stated on the label.

The 3 pin UK mains input plug contains a replaceable fuse. The rating of this fuse is shown on the charger label. Always replace with the same type and size of fuse as specified. Fitting of different fuses can result in damage to the charger or failure of the charger to operate properly.

If your charger has been specified for use in Continental Europe it will contain a European two pin plug which does not have a fuse. In this case the fuse is located in the fascia panel of the charger.

Fault finding guide

If having followed the correct steps to start battery charging the charger does not operate as described, then check as follows:

No charging indicator

The connection between the charger and the batteries has not been made.

Mains supply

Check that the mains supply is on, that any fuses are intact and that the charger is switched on.

Deeply discharged batteries

If the battery voltage is below 16 volts the charger will not commence charging.
