Deep cycle batteries are best suited for use
with 12 Volt operated lights, appliances and
inverters. Deep cycle batteries are designed
to have a majority of their capacity used
before being recharged. These are available
in many sizes and types. The most common
is a non-sealed, liquid electrolyte battery. The
non-sealed types have battery caps. The caps
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 many
factors: how far the batteries are depleted,
how long the voltage is being applied to
charge the batteries, how much voltage is
used 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.
At a minimum, 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 approximately 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 levels it is also a good idea to 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 and surrounding area when done. Carefully hook the
cables back to the battery. Coat the terminals with petroleum jelly or an anti-
corrsion grease.
