Plug the charger into a properly grounded outlet which supplies the correct input voltage.
The indicator light should now be on indicating that the charger is operating.
Determine the battery polarity. Most batteries identify the positive terminal with a “+”
sign or the color red and identify the negative terminal with a “
−
” sign or the color black.
Connect the red insulated output clip to the positive battery terminal and connect the
black insulated output clip to the negative battery terminal. If the charger is provided with
a polarized connector, make sure your battery plug is wired to match the output
connector. The
standard polarity of
the optional barrel
plug, p-clip, and
cigarette lighter
plugs are shown.
The charger should now be on and charging the battery and the indicator light should 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 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 help
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, an 8 amphours battery would require an 800 milliamp
charge. Larger or smaller capacity batteries can be charged with these chargers with the
