Guide to safe and lasting battery
How does charger work?
When the battery vollage is low, the battery charger outputs a large current to charge the
battery. When battery vollage is close to full, the battery charger outputs a small current.
When battery is full, the battery charger will output very little current which is almost
zero. Therefore. The battery will continually charge after connecting the charge, but will
not overcharge. It is better to charge no more than 24 hours.
How does the indicator light(LED) in charger display.
There are two LED indicator lights in the charger. The red indicator light is the power indicator
light. Regarding the other one, it is orange when charging and it will become green when the battery is
charged fully. The red one will sometimes still on after pulling the charger plug out from the power
socket; then you may think there is some thing wrong with the charger, however, in fact, it needs
seconds for the red light to snuff out when the battery voltage is up to 26V.
Other chargers can be used?
In order to charge safely and efficiently, we suggest using the charger supplied by
original manufacturer.
