Internal Lithium-ion Replacement Battery Pack
The internal Lithium-ion cells frequently suffer from deep-discharge cycles due to the device's persistent standby state, which eventually leads to the voltage falling below the minimum threshold required by the logic board to boot. When the battery reaches this state, the onboard charging circuit often fails to provide sufficient 'kickstart' current to bypass the BMS protection lock. Installing a new battery pack restores the electrochemical energy needed to satisfy the high inrush current required for the device's wireless and digital processing components during startup.
