CAUTION
Many types of petroleum based products
or battery by-products can damage
the paint finish. DO NOT allow these
types of chemicals to get on the paint
finish. If the chemicals splatter on to the
painted surfaces, immediately rinse the
surface using plenty of water and a mild
detergent.
Battery Maintenance
Liquid Lead
Acid (LLA)
battery cells
should be
checked at least
once a month.
The level should
be above the top
of the plates, but not overfull. The electrolyte
level should be approximately 3/8" below the
well to allow room for expansion while the
battery is being charged. Over-lling the battery
will allow the electrolyte solution to boil or gas
out of the battery cap. Remember to use only
distilled water to rell the battery. A battery with
a low electrolyte level will rapidly boil out the
water once the plates have been exposed to air.
Periodically check the batteries for corrosion
and cracks. Replace vent plugs that are cracked
or missing. Keep the top of the batteries clean.
The accumulation of electrolyte and dirt may
permit small amounts of current to ow between
the terminals, which can drain the battery.
Check the battery connections for tightness
and corrosion. If corrosion is found, disconnect
the cables (mark cable locations) and carefully
clean them with a mild solution of baking soda
and water, or an aerosol product specically
designed for battery maintenance. DO NOT
allow cleaning solution to seep into the battery
and 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. The battery cable to battery terminal
connections should be metal to metal. Coat
the terminals with petroleum jelly or an anti-
corrosion grease.
WARNING
Liquid lead acid batteries produce
hydrogen gas while charging. This
is highly explosive. DO NOT smoke
around batteries and keep all sources of
ignition or flames away from batteries.
The hydrogen gas may explode resulting
in fire, personal injury, property
damage or death.
Testing the Battery
A battery can be tested
and monitored several
ways. The monitor panel
on the hallway Systems
Control Center and the
optional monitor in water
service center show
voltage of the house
batteries. Press the Test
switch to check battery
status.
