You just saved my 5 amp hour battery that I left on a fan and went completely dead, and wouldn't take to the jump trick, can't thank you enough... I can't believe this video has got over 7k views and only 100 likes, you deserve more subscribers and likes. I've subscribed. Thank you.

I have exactly the same issue. 6ah battery was run down and won't charge or take a jump start.. I will give this a try.. Top man and great video. No annoying music either 😂

Super! It works!!! Thank you!!! ☺

Excellent fix! Thanks for sharing this. 👍 😊

I haven't seen this trick before, Nice!

I have a Skil 20V battery that would not charge after depleting it using my new Skil leaf blower. It would not jump either. I found a T10 torx driver and removed the cover. I noticed that alone caused the battery indicator LEDS to show 2 bars (none before). I placed the battery w/o cover in the charger and it's now charging. I see in the inside cover that there is what looks like globs of grease. Maybe that grease trapped the gasses from escaping? Anyway, that alone seems to have fixed my problem. I hope that helps others.

If my battery hasn’t held a charge for a couple years now and I’m just discovering this will it still work?
