Possible Causes
1. Battery Has Reached End of Life
Lithium-ion batteries typically degrade over time and may eventually stop accepting a charge.
2. Dirty Charging Contacts
Dust, moisture, or corrosion can prevent proper charging.
3. Faulty Charger or Cable
Always verify that the charger is functioning correctly before replacing the battery.
4. Internal Battery Protection Triggered
Extended storage or deep discharge may activate the battery’s protection circuit, preventing charging.
Recommended Action

2. Device Shuts Down Unexpectedly
Sudden power loss during use often indicates unstable battery voltage.
3. Battery Does Not Hold a Charge
If the battery quickly loses power while not in use, internal cell deterioration may be occurring.
