The battery has been discarded and cannot be saved.
Once the lithium battery is activated and used, it must maintain a certain amount of energy in the battery. If the lithium battery's energy is completely consumed, it will no longer be charged and will be discarded. Lithium batteries are used in various industries. When using this type of electrical appliance, even if it means that the energy is exhausted, there is still some energy left, usually between 5% and 10%. This is a protective measure for lithium batteries to prevent the battery from being completely exhausted. Rechargeable batteries self-discharge and slowly deplete even if not in use. Once the battery is completely depleted, it can no longer be charged and must be reactivated before it can be used. The activation process of lithium batteries must be carried out ina special environment. Ordinary charging will never activate lithium batteries. Only the rechargeable battery manufacturer can complete the activation of lithium batteries, but the manufacturer will never activate an old battery, because the cost of activating an old battery is not lower than that of producing a new battery.
You can only purchase new batteries.
1. Use the charger on a fast charging station to charge: Lithium batteries tend to lose power if left for a long time. If you want to activate them, you can directly push the electric. vehicle at a fast charging station on the street. Find a charger like this to recharge. The current in such places is generally relatively large, and the battery can be activated quickly, then it can be replaced with a corresponding charger and continue to be fullloaded.
2. Use a high voltage charger to charge: Find a high voltage charger to charge the low voltage lithium battery. Normally, it is better to use a charger suitable for the battery, which is better for the battery. However, if the lithium battery cannot be charged due to power loss, you can use a high voltage charger to charge it to activate the battery.
3. Turn on the headlights when charging, then recharge: If the scooter is left without a charge for a long time and the lithium battery is "starving", you can turn on the headlights while charging, then recharge. Connect the charger and see if the charging light on the charger changes. If so, it can charge normally.
