Step 2: Check Battery Seating and Contacts
- Remove the battery from the charger.
- Inspect the metal contacts on both the battery and charger for dirt, dust, or corrosion.
- Clean contacts gently with a dry cloth or a soft brush.
- Reinsert the battery firmly, ensuring it clicks into place.
Step 3: Reset the Charger
Unplug the charger from the power outlet. Wait for at least 30 seconds to allow internal circuits to reset. Plug it back in and attempt to charge a known good battery.
Step 4: Test with Different Batteries
If you have multiple batteries, try charging each one. If some batteries charge normally while others don’t, the issue may be with the battery rather than the charger.
Step 5: Inspect for Damage and Overheating
Check the charger and batteries for visible damage, swelling, or burns. Ensure the charger is not overheating; let it cool down if it feels hot, then try again.
