Charge the battery at any time - not just when it is fully discharged
The charging port is in the battery, so it can be charged on or off the bike
Plug your charger into the wall first, lift the rubber cap and then plug in your charger to the battery

While charging, the charger will display a red light and green when fully charged
Properly close the rubber cap before reusing your bike. If the battery is in storage you must charge every two months
Avoid charging immediately after a demanding ride to prevent excessive heat that can increase wear on the cells of the battery
