Make sure it's in the charger.

Received it and started using it immediately. Set up and start charging, red light. Remains red for many hours. I was then curious as to why it took more than 4 hours for it to turn green. Then I touched it and saw the light turn green. I took out the battery and it works great in a flashlight. Maybe it was charging and turning green and I wasn't there to catch that part. For that I give four stars.

Pros
  • LED AND SMART CHARGER: When the LED is RED, the battery is not in the charger or charging; If it is GREEN, it means it is fully charged; Make sure you insert the battery and make contact with the charger. Automatically detects the battery type and starts charging or stops charging; No additional setup is required to charge a 3.6V or 4.2V battery. This charger protects your battery when it is fully charged, no matter how long you leave the battery on the charger.
Cons
  • unreliable
