BBattery Charging
To avoid personal injury:
A When the battery is being activated, hydrogen
and oxygen gases in the battery are extremely
explosive. Keep open sparks and flames away
from the battery at all times, especially when
charging the battery.
A When charging battery, remove battery vent
plugs.
A When disconnecting the cable from the battery,
start with the negative terminal first.
When connecting the cable to the battery, start
with the positive terminal first.
A Do not check battery charge by placing a metal
object across the terminals.
Use a voltmeter or hydrometer.
1. Make sure each electrolyte level is to the bottom of
vent wells. If necessary add distilled water in a well-
ventilated area.
2. The water in the electrolyte evaporates during
recharging. Liquid shortage damages the battery.
Excessive liquid spill damages the excavator body.
3. To slowly charge the battery, connect the battery
positive terminal to the charger's positive terminal and
the negative to the negative one. Then, recharge in the
standard fashion.
4. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte falls between
1.27 and 1.29, charge has completed.
6. When exchanging old battery for a new one, use
battery of equal specification.
