Figure 5.134: Battery Charging
CAUTION
•
Ventilate the area where batteries are being charged.
•
Do NOT charge a frozen battery. Warm to 16°C (60°F) before
charging.
•
Do NOT connect or disconnect live circuits. To prevent
sparks, turn off charger and connect positive cable first.
PROTECT YOUR EYES.
•
If charging battery in windrower, disconnect POSITIVE
battery cable before connecting charger cable, then connect
ground cable last, away from battery.
•
Stop or cut back charging rate if battery feels hot, or is
venting electrolyte. Battery temperature must NOT exceed
52°C (125°F).
•
The maximum charge rate in amperes should be NO MORE
than 1/3 of the battery
’
s reserve capacity minute rating. If
the terminal voltage exceeds 16.0 volts while charging,
reduce the charge rate.
•
Continue charging and reduce the rate as needed until a two
hour period results in no increase in voltage or decrease in
current.

WARNING
•
Follow all battery manufactures instructions and precautions.
•
Gel and AGM (Absorbed Glass Mat) batteries require a voltage-limited charger. Charging a gel or AGM battery on a
typical shop charger
—
even one time
—
may greatly shorten its life.
•
If the electrolyte is accessible, verify that plates are covered before beginning to charge. At the end of charge, add
distilled water as needed to bring levels to the proper height. If water is added, charge for an additional 30 minutes
to mix. If electrolyte levels are low, but battery is not accessible, remove battery from service.
18. Open circuit voltage with no charging/discharging for 8 hours or more.
19. Charging time depends on battery capacity, condition, age, temperature, and efficiency of charger.
