How to Choose a Deep Cycle Battery
Automotive batteries and deep cycle batteries are similar, but the way they release the power differs. Car batteries release the surge of power needed to turn the starter motor, and afterward the alternator replenishes the charge. Deep cycle batteries are designed to release their energy over a longer period and to discharge more fully before being recharged. Deep cycle batteries are commonly used in golf carts, RV's, boating, backup power or lighting, and for storing power generated by solar panels. Follow this guideline to choose the right deep cycle battery for your application. Does this Spark an idea?

1
Follow the device manufacturer's recommendations to determine the dimensions, voltage, and capacity in amp-hours for the deep cycle battery. Too weak a battery will deplete its power prematurely. One that is too strong may not discharge enough before recharging, resulting in decreased battery life.

2
Choose a marine battery for boating, aircraft or RV use if the battery must provide a burst of engine cranking power in addition to a prolonged discharge.

3
Select a conventional flooded battery if it will be located in a well-ventilated area and can be secured against tipping or spilling. Flooded batteries need to be topped off with water occasionally, so locate them where they can be serviced easily.
-
4
Choose a sealed AGM (Absorbed Glass Mat) or gel battery if the battery must be tilted during storage or use, or if there is limited ventilation. These batteries require no regular servicing and are often used in electric vehicles and power backup systems.
-
5
Use NiCad (nickel-cadmium) or NiFe (nickel-iron) batteries where long battery life is a necessity. Though they are more expensive and less efficient, these alkaline-based batteries last 15 to 25 years in most applications.

Tips & Warnings
All parts of a lead-acid battery can be reclaimed. If you're replacing one, take the old one to a recycling center.
Observe the battery maker's cautions and guidelines when installing or servicing a battery.
