Care and Maintenance of Marine Batteries

Many boaters do not even think about the battery inside their jet ski or boat, until the engine fails to turn over. By understanding the marine battery and the maintenance required, the avid boater can keep their boat running, while extending the lifespan of the battery.

The Absorbent Glass Mat (AGM) battery leads the way in marine batteries by using the latest advances in deep cycle battery technology, incorporating both safety and durability. The electrolyte solution is stored using fiberglass separators, which make the battery spill proof. They are resistant to damage that can be caused by either vibration or impact and can be stored in even the most inaccessible parts of the boat. They do not need to be refilled and are completely sealed.

Charging and discharging are important with a deep cycle marine battery, as the battery will not reach maximum storage capacity until numerous charge/discharge cycles have been completed. A quality multiple stage charger with 8 amps minimum and 16 amps maximum is recommended. A charger with 'float mode' can help keep marine batteries charged for longer periods of time when not in use. Generally, 20-50 charge/discharge cycles are needed before maximum storage capacity can be attained. A new battery should be broken in gradually and not completely depleted. By disregarding this, a battery's lifespan can be reduced by months or even years.

An overlooked, but necessary, maintenance technique is cleaning the battery. Residue can build up on the top of the battery causing discharge. Annually, a wire brush should be used to free the residue and the terminals should be coated lightly with grease. While this procedure is taking place, it is also important to do a visual inspection of the battery to make sure the battery has not been struck by an object or dropped.

'Equalizing' is a process that is accomplished by keeping a low current charge after a normal cycle has been completed for an extended period of time. This keeps cells in balance to perform equally during use and should be performed weekly during heavy boating seasons. The battery should also be brought to a full charge at least once every three weeks.

With proper care and maintenance, a deep cycle battery can provide the avid boater dependable service. U.S. Battery ranks as a leading manufacturer of marine batteries.
