Note
The temperature is an ambient temperature of the battery
that has been exposed to for the preceding few hours.
Caution
When batteries are being charged, an explosive
gas forms beneath the cover of each cell. Do not
smoke near batteries on charge or which have
recently been charged.
Do not break live circuits at the terminals of the
batteries on charge. A spark will occur where the
live circuit is broken.
Keep all open flames away from the battery.
Battery electrolyte temperature may temporarily be
allowed to rise to 55OC (131 OF). Increase of
electrolyte temperature above 55OC (131 "F) is
harmful to the battery, causing deformation of battery
cell, decrease in life of battery, etc.
CHARGE RATE
If the test indicator is white, the battery should be
charged as outlined below.

OPEN CIRCUIT VOLTAGE TEST (3)
I
1. Turn headlights on for 15 seconds.
2. Turn headlights off for 2 minutes to allow battery
voltage to stabilize.
3. Disconnect cables.
4. Read open circuit voltage.
5. If the open circuit voltage is under 12.4 volts,
I
charge the battery. (See BATTERY CHARGING)
LOAD TEST (4)
1. Connect a load tester to the battery.
2. Load the battery at 15 amps for 15 seconds to
remove surface charge.
3. Load the battery at the recommended discharge
rate. (See LOAD TEST RATE CHART)
4. Read voltage after 15 seconds and then remove
the load.
5. If the voltage is not maintained at the minimum
voltage in the LOAD TEST CHART throughout the
test, the battery should be replaced.
I
When the dot appears or when maximum charge
shown below is reached, charging should be
stopped.
NOTE
When the charging is performed at 5 amps,
charging is virtually loo:! three hours after the
indicator's indication changes from white to blue.
Use fast charging only in an emergency.
If the indicator does not turn to blue even after the
battery is charged, the battery should be replaced;
do not overcharge.
