For smaller batteries, 30 AH (ampere hour) or less, use 2
AMP setting. Small batteries may not be able to accept the
potential of the 10 or 12 AMP setting. Unconverted energy will
result in excess heat which the battery may not be able to
dissipate, thus resulting in damage to the battery.
For larger batteries either setting may be used.
CHARGE RATE SWITCH
These chargers are for use with 12 volt lead-acid batteries
only.
OUTPUT VOLTAGE

known as cycling and can be recognized by an audible
clicking sound.
2. These battery chargers are equipped with an electronic
control circuit which automatically governs the charge
rate to your battery. The charger will satisfactorily
charge Maintenance Free and Conventional batteries.
