Certain precautions must be observed during the charging procedure:

• Never recharge batteries except in a clean, well ventilated space away from customer or employee walkways.

• Never allow smoking, welding or open flames in or around the area. Batteries give off explosive gases when charging and serious injuries can occur.

• Use only cables and clamps which are well insulated and in good condition to make connections between batteries and chargers. Keep wrenches/pliers/screwdrivers away from battery racks.

• Make connections between batteries and the charger and disconnect only when the charger switch is in the OFF position and, preferably, when the charger main supply cable is withdrawn from the socket.

• Keep battery vent caps in position during the recharge.

• If batteries need water additions to re-level electrolyte, do not add water before starting the recharge unless level is below the plates. Electrolyte volume expands during recharge and excess may flood over battery covers, causing damage to cables, clamps, racks and floors. Add water 2 to 3 hours before terminating the recharge. Fill batteries with distilled water, never tap water.

• Read and understand the charger manufacturer's operating instructions.

• Some modern chargers incorporate electronic switches in the circuit which will not operate if the battery does not exceed the trigger voltage. This can create an appearance that a very deeply discharged battery will not accept charge. The manufacturer's instructions will give the method of overriding the electronic switch.

• Other chargers incorporate thermally operated fuses which might operate on-off if the battery initially accepts maximum output current for an extended period. The appearance of intermittent charge acceptance can be confusing.

• Dry battery containers and covers, clean terminals and securely refit vent caps at the end of battery charge and testing, before returning batteries to stock or fitting to vehicles.

Battery terminals should be cleaned with a paste of baking soda periodically to protect against corrosion. Apply a thin coating of Vaseline once it's clean.
