HOW BATTERIES CHARGE
A charger DOES NOT FORCE current into a battery - it
makes a limited amount of current available and the battery
draws as much of it as it needs, up to or slightly greater than
the rated output current capability of the charger.
The closer a battery is to zero charge (dead battery), the
more charging current it will want to draw. When charging
begins, on a dead battery, the chargers ammeter will
register toward the high end of the ammeter scale and
move toward zero as the battery becomes more fully
charged. KEEP IN MIND, the ammeter registers the
amount of amperage being drawn from the charger by the
battery, not what the charger is capable of delivering.
NOTE: A slow bubbling sound may be heard coming from
the battery during the charging process. This is a normal
condition and just another indicator the battery is being
charged.
To reduce the risk of battery overcharging, it is important to
thoroughly read this instruction manual.
SPARK PREVENTION
MAKE SURE no sparks or flames occur near the battery,
especially during charging. It takes very little to ignite the
explosive gasses produced by a lead-acid battery. Read,
understand, and follow the safety information provided in the
SAFETY SUMMARY section of this manual before attempt-
ing to work with or near a lead-acid battery.
For more information about batteries and battery charging,
contact Battery Council International at (312) 644-6610, and
request their BATTERY SERVICE MANUAL, which is avail-
able for a nominal charge.
DEEPLY-DISCHARGED LEAD-CALCIUM BAT-
TERIES
Some modern batteries can cause charging problems if they
have been deeply discharged. The plates in these batteries
began sulfating quickly, forming a barrier to accepting a
charge. This condition will be indicated by a extremely low
(or zero) ammeter reading. A deeply discharged battery
such as this may take as long as 4 to 8 hours before it will
accept a charge.
