Charging
For charging, plug the battery into the charger. You will see a red light on the
charger indicating that it is charging. Once the light turns green the battery is
at 100% and the charger will automatically stop charging.
Although the charger does automatically shut off, it is not recommended you
leave the battery on the charger for long periods of time. In the rare event that
this function fails it can cause serious damage to the battery.
Charging should take 4 - 6 hours. If your battery is still not fully charged after
12 hours on the charger, contact MJM as there is likely something
wrong with the battery or charger.
• avoid blocking the fan on the charger to prevent overheating
• avoid charging in extreme temperatures. Charging between
10 - 25 degrees Celsius is ideal
• do not charge in strong sunlight
• only use the charger that has been supplied to you. If you require
a new charger contact MJM and we will be happy to assist
