This question already has an answer here:

On a long trip with a lot of wind my 400Wh battery went empty.When i tried to charge it at home it refuses to charge. The first of the five leds is flashing. Strange because in the manual is written 1,3,5 leds or 2,4 there is nothing about only the fisrt one. Any suggestions?

  • Unplug it all, wait overnight, and try again. If that doesn't change it, take the setup to Batteries Plus. – Daniel R Hicks Feb 8 at 18:56

    Involve the support department of the supplier - they'll tell you if its fixable or if the battery has simply died through age. Remember batteries are consumables and you should budget for a new one every ~3 years. – Criggie Feb 9 at 5:39

When you discharge a lithium-ion battery all the way you can run into serious problems. If the battery is relatively new it may be under warranty and an exchange would be your best bet.

The battery contains electronic circuitry designed to prevent a total discharge. If that circuitry fails the battery is ruined. If the internal voltage of the battery falls below a critical level this circuitry will NOT allow the battery to charge. Your charger's refusal to charge the battery indicates a problem with this circuitry.

If your other options don't work, and you can't exchange the battery for a new one, you can try putting the battery in your fridge (not the freezer) for an hour or so and see if that will help jump start it. Cool for an hour and try charging.

In my experience, once this happens to a battery it's well on it's way to being dead forever, even if you can recharge it once or twice.

  • As i mentionrd in the beginning the first of the five leds was flashing. After a few hours the blinking went more rapid until it stopped. Battery still refuges to charge. – stratos abatzis Feb 9 at 4:51
  • I can't exchange the battery for a new one. I am willing to do the freeze trick, but i dont know how to jump start it after. – stratos abatzis Feb 9 at 4:58
  • The first led blinking forever indicates the charger is attempting to work, but the battery is not charging. – Gary E Feb 9 at 19:30
  • DO NOT freeze the battery. Put in the the refidgerator, not the freezer. – Gary E Feb 9 at 19:31
