Deep Cycle batteries are constructed to maintain a continuous flow of energy. Some applications which require deep cycle batteries are trolling motors, house lights, stereo systems and motor home accessories. They are designed to endure the frequent, complete discharge and recharge essential these applications. This is called "Deep Cycling".

Automotive batteries have a completely different plate design and grid pattern. The thinner plates and standard paste design provide more initial cranking amps, but could never hold up to the rigors that a deep cycle battery is put through. If an automotive battery were cycled in a deep discharge application, it would fail considerably sooner than would a deep cycle battery.

Keep your battery clean and free of corrosion. Use baking soda or battery cleaner (available from your Centennial retailer). Flush entirely with water. (A wire brush is sometimes helpful.)

Check the water level frequently, especially before charging. If the level is low, add sufficient distilled water to cover the plates. After charging bring the water level up, if necessary, no higher than the bottom of the vent walls. DO NOT OVERFILL. Distilled water is best for long life, but if unavailable, it is better to use good drinking water than nothing at all. Remember..... if a portion of the plate gets dry, it loses much, if not all, of its capacity.

Never overcharge your battery. This can lead to water loss and grid corrosion that can greatly reduce the life of the battery. A charger with an automatic timer is a great idea.

Never "fast charge" or "boost" a deep cycle battery. A slow charge is always best.

Follow the instructions, safety manual, and procedural recommendations on the charger.

Select a charger with a capacity sufficient to fully recharge the battery within 8 - 12hours.

Store it in a cold place, but not where it will be consistently below 32 degrees Fahrenheit. All batteries discharge naturally, but the lower the temperature, the slower the discharge.
