CHARGING TIME INSTRUCTIONS
CHARGING TIME INSTRUCTIONS
1"2VOLT BATTERIES
The AUTOMATIC CHARGING CIRCUIT will prevent over
charging a 12 volt battery, so accurate calculation of length of
charging time is unnecessary. When full charge is reached, the
output of the charger will be turned off and the green CHARGE
COMPLETE INDICATOR will turn on. If the charger is left
connected to the battery, it will monitor the battery's state of
charge and turn the charger's output back on if the battery
discharges.
However, for an idea as to how long the charging process may
take, see the following CHARGING TIME CHART or CHARGING
TIME EQUATIONS.
6 VOLT BATTERIES
The 6 volt charging setting is a MANUAL operation. When the
battery reaches full charge, the charger must be promptly
unplugged from the AC outlet and disconnected from the battery.
If this is not done, overcharging can occur that could result in
damage to the battery.
Use the CHARGING TIME CHART or CHARGING TIME
EQUATIONS to determine how long to charge your 6 volt battery.
ALWAYS set a time-warning device, such as an alarm clock, to
remind you to discontinue charging.
DETERMINING TIME TO CHARGE
1. Determine the battery's present state of charge with a
hydrometer or electronic percent-of-charge tester.
2. Convert hydrometer readings to percent of charge.
