CHARGING THE BATTERY
CAUTION:
Do not “quick charge” a fully discharged battery.
Keep the battery away from open flame while it is being charged.
When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark.
If battery electrolyte temperature rises above 55°C (131 °F), stop charging. Always charge battery
at a temperature below 55 °C (131 °F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be
replaced.
Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00B79
CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be
done as a set from start to finish.
If battery surface charge is detected while testing, the tester will prompt you to turn on the headlights to
remove the surface charge.
If necessary, the tester will prompt you to determine if the battery temperature is above or below 0 °C
(32 °F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER ” to
make the selection.
