Check the Battery and Charger Connections
- Ensure the battery is fully seated in the charger socket, with no debris or corrosion on the contacts.

Evaluate the Battery Condition
If the battery is old or heavily used, it might be unable to hold a charge. Look for visible damage, swelling, or corrosion. If any are present, replacing the battery is recommended.
Test in a Controlled Environment
Allow the battery and charger to sit in a moderate room temperature (around 20°C/68°F) for a few hours, then attempt to recharge. Extreme cold or heat can prevent proper charging.
