Must Read Before Using the Battery

Due to the special manufacturing process of batteries, prolonged storage may cause the battery to enter a dormant state and fail to function normally (this is not a quality issue). It requires extended charging to reactivate the battery. Please read the following possible situations you may encounter after purchase carefully:

Possible Battery "Dormancy" (Can Try Reactivation)

Displays 100% charge but shuts down immediately when the charger is disconnected
Shows a notification of "Battery not charging / Battery error, please replace"
Solution Suggestion: Keep the charger connected and let it charge for 2-4 hours, then press and hold the power button for 15-30 seconds to reset before attempting to power on.No response when plugged in, unable to power on

Incompatibility Issue (Return Recommended)

Only 10-20 minutes of usage after a full charge
Battery health drops sharply to below 70% after a small number of charge cycles
Note: This type of issue is generally related to incompatibility with the laptop model. Even if some laptop models appear to match, they may not work due to inconsistent voltage used by the original factory.Fails to charge normally or experiences frequent power drops
