BATTERY RE-ACTIVATION
HOW TO RE-ACTIVATE A BATTERY THAT NO LONGER CHARGES
The over-discharge protection voltage for this battery is set at 10V,
and if the voltage drops below this level, the Battery Management
System (BMS) will trigger a safety cutoff to protect the battery.
In such an event, you must follow the reset procedure for the battery
as outlined below:
METHOD 1 (EASY)
1. Disconnect the load from the battery and set it aside for at least 30
minutes.
2. The battery should recover to anormal voltage level
automatically.
3. The battery can then be fully charged for normal use.
It is important to note that in some cases, METHOD 1 may not be
sufficient, and you may need to proceed with METHOD 2 or METHOD
3 to reset the battery.
METHOD 2 (REQUIRES A CHARGER WITH 0V FUNCTION )
1. Use a charger equipped with a 0V charging function.
2. Charge the battery fully using this charger on its 0V setting.
3. Once the battery is fully charged, the BMS will reset automatically.
4. The battery can now be used as normal.
METHOD 3 (REQUIRES A SECOND BATTERY)
A lead-acid battery with a voltage more than or equal to 12V and
less than or equal to 14.6V will also work.
1. Connect the battery in parallel with another fully charged 12V
lithium battery.
2. Allow the battery to charge in parallel for at least one minute.
3. Disconnect the second battery and charge your battery fully
using a regular lithium battery charger.
4. Once fully charged, the BMS will reset automatically, and the
battery can be used normally.
