Battery electrolyte is a diluted sulfuric acid. Battery acid
can cause severe injury or death. Battery acid can cause
blindness and burn skin. Always wear splashproof safety
goggles, rubber gloves, and boots when servicing the
battery. Do not open a sealed battery or mutilate the battery
case. If battery acid splashes in the eyes or on the skin,
immediately flush the affected area for 15 minutes with large
quantities of clean water. Seek immediate medical aid in the
case of eye contact. Never add acid to a battery after
placing the battery in service, as this may result in hazardous
spattering of battery acid.
Battery acid cleanup. Battery acid can cause severe
injury or death. Battery acid is electrically conductive and
corrosive. Add 500 g (1 lb.) of bicarbonate of soda (baking
soda) to a container with 4 L (1 gal.) of water and mix the
neutralizing solution. Pour the neutralizing solution on the
spilled battery acid and continue to add the neutralizing
solution to the spilled battery acid until all evidence of a
chemical reaction (foaming) has ceased. Flush the resulting
liquid with water and dry the area.
Battery gases. Explosion can cause severe injury or
death. Battery gases can cause an explosion. Do not
smoke or permit flames or sparks to occur near a battery at
any time, particularly when it is charging. Do not dispose of
a battery in a fire. To prevent burns and sparks that could
cause an explosion, avoid touching the battery terminals with
tools or other metal objects. Remove all jewelry before
servicing the equipment. Discharge static electricity from
your body before touching batteries by first touching a
grounded metal surface away from the battery. To avoid
sparks, do not disturb the battery charger connections while
the battery is charging. Always turn the battery charger off
before disconnecting the battery connections. Ventilate the
compartments containing batteries to prevent accumulation
of explosive gases.
Battery short circuits. Explosion can cause severe
injury or death. Short circuits can cause bodily injury and/or
equipment damage. Disconnect the battery before
generator set installation or maintenance. Remove all
jewelry before servicing the equipment. Use tools with
insulated handles. Remove the negative (–) lead first when
disconnecting the battery. Reconnect the negative (–) lead
last when reconnecting the battery. Never connect the
negative (–) battery cable to the positive (+) connection
terminal of the starter solenoid. Do not test the battery
condition by shorting the terminals together.
Refer to this section for general battery information
and maintenance. Also consult the battery
manufacturer’s instructions for battery maintenance.
All generator set models use a negative ground with a
12-volt engine electrical system. Consult the
generator set nameplate for the engine electrical
system voltage. Consult the generator spec sheet for
battery capacity recommendations for replacement
purposes. Wiring diagrams provide battery connection
information. See Figure 2-13 for typical battery
connections.

Connection
Clean the battery and cables and tighten battery
terminals using the service schedule
recommendations. To prevent corrosion, maintain
tight, dry electrical connections at the battery
terminals. To remove corrosion from battery terminals,
disconnect the cables from the battery and scrub the
terminals with a wire brush. Clean the battery and
cables with a solution of baking soda and water. After
cleaning, flush the battery and cables with clean water
and wipe them with a dry, lint-free cloth.
WARNING
!
Sulfuric acid in batteries.
Can cause severe injury or death.
Wear protective goggles and
clothing. Battery acid may cause
blindness and burn skin.
