A 12-volt battery with minimum of 400 cold cranking
amps is generally recommended for starting in
all conditions. A smaller capacity battery is often
sufficient if an application is started only in warmer
temperatures. Refer to the following table for
minimum cold cranking amp (cca) capacities, based
on anticipated ambient temperatures. The actual
cold cranking requirement depends on engine size,
application and starting temperatures. The cranking
requirements increase as temperatures decrease and
battery capacity shrinks. Refer also to the operating
instructions for the piece of equipment for specific
battery requirements.
If the battery charge is not sufficient to turn over the
engine, recharge the battery.
Regular maintenance is necessary to prolong battery
life.
WARNING: Explosive Gas!
1. Regularly check the level of electrolyte. Add
distilled water as necessary to maintain the
recommended level.
NOTE: Do not overfill the battery. Poor
performance or early failure due to loss
of electrolyte will result.
2. Keep the cables, terminals, and external surfaces
of the battery clean. A build-up of corrosive acid
or grime on the external surfaces can cause the
battery to self-discharge. Self-discharge occurs
rapidly when moisture is present.
3. Wash the cables, terminals, and external surfaces
with a mild baking soda and water solution.
Rinse thoroughly with clear water.
NOTE: Do not allow the baking soda solution
to enter the cells, as this will destroy the
electrolyte.
To test the battery, you will need a DC voltmeter.
Perform the following steps (see Figure 7-2):
1. Connect the voltmeter across the battery
terminals.
2. Crank the engine. If the battery drops below 9
volts while cranking, the battery is too small,
discharged, or faulty.
