About Charging Batteries
Batteries draw as much power as they need from charger. The charger does not
force current into battery. When a battery is close to being dead or very low charged,
it will want to draw more current. When a dead or low battery is charged, the charger’s
ammeter will register at high end. As the battery charges, the reading will move down
toward the low end, resting on zero, when battery is fully charged. See Figure 1 below.
Note: The ammeter shows the amount of current being drawn from the charger. It
does not show what the charger is capable of delivering. When the battery is
fully charged and registering zero on the ammeter, a small charge will continue to
move from the charger to the battery. If you do not disconnect the charger from
the battery, eventually the heat build up from the charge will cause the battery
acid to boil and overcharge the battery causing damage to the battery. You
must constantly monitor battery charging progress and if battery gets warm, stop
charging it immediately.
Note: When charging a battery with a built-in hydrometer eye, do not depend on the
hydrometer eye to determine the battery charge level.
WARNING! Use this charger only on ooded lead-acid batteries. Other batteries may
be damaged or may overheat, leak, or catch re.
