Step 2: Verify Power Source
Test the outlet with another device to confirm it has power. Try plugging the charger into a different outlet or power strip to rule out outlet issues.
Step 3: Test the Charger
- Ensure the charger’s LED indicator (if available) lights up when plugged in.
- If the charger has a reset button or fuse, check or replace if necessary.
- Try charging a different compatible battery if available to determine if the charger is faulty.
Step 4: Examine the Battery
If the battery is old or has been stored improperly, it may be unable to charge. Try using a different, known-good battery to test if the issue is with the battery itself.
Step 5: Address Overheating or Safety Locks
If either the battery or charger is hot, allow them to cool for at least 30 minutes before retrying. Do not attempt to charge if overheating occurs, as it can damage the battery or pose safety risks.
