It is no longer necessary to completely discharge and recharge modern lithium batteries. It is recommended that batteries are always recharged when possible even after a short journey; this keeps the battery healthy and always available for longer journeys.
Never leave a battery completely depleted or drained; this will prevent the battery voltage from dropping below safe levels, which can cause irreparable damage to the cells.
During long periods of storage and non-use keep the battery about 2/3 full and top up for two hours every eight to twelve weeks.
For optimum power and range keep battery in a Dry/Warm room above 15 degrees Celsius.
A lithium electric bicycle battery will take between 2 and 6 hours to charge depending on the capacity of the battery and the Amperage of the battery charger.
