1. Battery State – Depending on the voltage of your battery, it may take up to 10 hours to
charge. Batteries with higher voltage can usually be charged in a few hours.
2. Battery Rating – A higher rated battery will take longer to charge than a lower rated
battery under the same conditions. A battery is rated in ampere-hours (Ah), reserve
capacity (RC) and cold-cranking amps (CCA).
3. Charge Rate – The charge rate is measured in amps. A battery charged at a lower rate
will take longer than a battery charged at a higher rate. However, smaller batteries can
be easily damaged by charging at a rate which is too high for the capacity of the battery.
4. Temperature – Cold temperature will affect a battery’s ability to accept a charge.
Charging in cold temperatures will increase the amount of time required to charge a
battery.
Clean cords and clamps each time you are finished using the charger. Wipe off any
battery fluid or debris that might have come in contact with the clamps to prevent
corrosion.
Store the power and output cable neatly to prevent damage.
Occasional cleaning of the battery charger case with a soft cloth will help protect the
finish.
Always unplug the charger when not in use.
Keep the charger stored in a cool, dry place.

Problem
Cause
Solution
Loose connection at the

Check the connection.
No AC power at outlet
Ensure power is present
at outlet.
The LED indicator does
not illuminate when the
charging cable is
connected to the battery.
Overheating shutdown
Remove objects covering the
unit. Place the unit in a cooler
location.
The battery voltage is too
low.
Check the battery voltage with
a multimeter. Recycle the
battery if the battery voltage is
too low.
The battery clips are not
connected properly to the
battery terminals.
Check the connection and
re-attach the clips to the
terminals.
Reverse polarity
Check the polarity.
The green LED light
stays on even when
batteries are not full.
