Step 2: Inspect the Batteries and Charger
- Test the batteries with another compatible charger if available to verify they are functioning properly.
- Look for any visible damage to the batteries or charger, such as cracks or burn marks.

Step 3: Allow the Charger to Cool and Reset
If the charger has overheated, unplug it and allow it to cool for at least 30 minutes. Once cooled, reconnect and attempt to charge again.
If blinking persists, try resetting the charger by unplugging for 10 seconds, then plugging back in.
