The input voltage setting is displayed on the selection switch on the back of the unit. If
this setting must be changed, make sure the power cord is disconnected while operating
the switch. Operating the switch while power is applied may cause damage to the switch
or charger. Plug the power cord into a properly grounded outlet which supplies the
correct input voltage.
The charger should now be on and charging the battery and the indicator light should
now be yellow. The yellow charge light will stay on until the battery is about 95%
recharged. At this point the indicator will turn green and the charger will begin the float
charge. The battery should be left connected to the charger for at least an additional three
hours to ensure a 100% recharge. To help your battery keep its full capacity, we
recommend the battery be left connected to the charger in float charge mode until ready
to use. This will prevent chronic undercharging, a leading cause of premature battery
failure. The float charge is low enough to prevent overcharging, but high enough to allow
the battery to replace its standing losses and maintain a 100% state of charge. The battery
may be left connected to the charger indefinitely, in float charge mode, without danger of
overcharging.
CHARGING NOTES AND TIPS
For safer and more efficient charging, batteries should be charged with higher voltages
when cold and lower voltages when warm. This unit incorporates automatic temperature
compensation of the output voltage. It will increase the charge voltage in cold conditions
and decrease charge voltage in warm conditions. For this feature to work properly, the
battery and charger should be located in the same environment (allow the battery and
charger to stabilize at room temperature before charging). Initially, the charger voltage
may read a little high until its internal temperature warms during operation, thereby
lowering the voltage.
Make sure that you only charge the proper voltage battery. Trying to charge a lower
voltage battery will cause severe overcharging and trying to charge a higher voltage
battery may damage the charger.
These battery chargers are designed to charge a battery at the C/10 rate (battery capacity
divided by 10 hours). Therefore, a 20 amphours battery would require a 2 amps charge.
Larger or smaller capacity batteries can be charged with these chargers with the
following precautions (refer to these charger specifications & your battery documentation
for proper switch and charge currents to determine compatibility with this charger):
o
When charging a larger capacity battery, it is possible the current will never
reduce sufficiently for the charger to enter float mode. Should this occur the
battery may become damaged due to over charging. In such a case, the capacity
is too great and the battery should be charged with a higher current charger or a
parallel charger.
o
When charging a smaller capacity battery, the battery may be undercharged
because the charger switches into float charge mode too early (relative to
