Deep Cycle Battery
Deep cycle batteries, best suited for use with 12 Volt operated lights, appliances and inverters, are designed to
have the majority of capacity used before being recharged. These batteries are available in many sizes and types.
The most common is a non-sealed, liquid electrolyte battery. The non-sealed types have battery caps that should
be removed periodically to check the level of electrolyte. When a cell is low, only distilled water should be added.
Water consumption will vary depending on factors such as: how far the batteries are depleted, how much voltage,
how long the voltage is being applied to charge the batteries and how often this occurs.
NOTE:
Tap water contains minerals which can alter battery chemistry and ruin the battery. Use
only distilled water when refilling the battery.
Battery Maintenance
The battery electrolyte level should be checked at least once a month. Check the level sooner if the battery is
frequently used. The level should be above the top of the plates, but not overfull. Most batteries have a plastic cup
or well. The electrolyte level should be about 3/8” below the well to allow room for expansion while the battery
is being charged. Over-filling the battery will allow the electrolyte solution to boil or gas out of the battery cap.
Remember to use only distilled water to refill the battery. A battery with a low electrolyte level will boil the water
out rapidly once the plates have been exposed to air. This process may take only a matter of hours. If this has
happened the battery is more than likely damaged.
After checking the battery’s electrolyte level, also check the battery connections for tightness and corrosion.
If any corrosion is found, disconnect the cables (make sure to mark their locations) and carefully clean them
with a mild solution of baking soda and water. There are also aerosol products available that will work. This will
neutralize any acid that may be present. Do not allow the solution to enter the battery as this will damage the
electrolyte balance. Use water to rinse the top of the battery area when done. Hook the cables back to the battery.
Coat the terminals with petroleum jelly or an anti-corrosive grease.
The battery cable to battery terminal connections should be metal to metal. Periodically check the batteries for
corrosion. Look for cracks and check the vent plugs. Replace if any are cracked or missing. Keep the top of the
batteries clean. The accumulation of electrolyte and dirt may permit small amounts of current to flow between the
terminals, which can drain the battery.
WARNING:
Liquid lead acid batteries produce hydrogen gas while being charged. This is highly
explosive. Do not smoke around batteries. Extinguish all flames in the area. Batteries may
explode resulting in fire, personal injury, property damage or death.
CAUTION:
Always wear safety glasses when servicing the battery.
