Protection against overcharging and overdischarging
A lithium-ion battery with overcharge and discharge protection circuits is used in the OneKey wallet battery. As a result, leaving the charger plugged in all the time or plugging it into a computer has no effect on the battery life and will not harm your wallet. A gadget will not be harmed by a sudden low battery shutdown while in operation.
How can it be kept for a long time?
Because lithium batteries have their own wear and tear, it is best to maintain them completely charged when not in use for an extended period of time. If the device is empty before storage, its own loss will cause the internal resistance of the battery to grow, resulting in permanent battery damage.
