Title: Battery with a dent
Post by: Paul Taylor on June 15, 2014, 04:29:35 PM
Someone had a mishap yesterday and paddy caked a plane. The battery got a dent in one corner.
Is this just a fire waiting to happen?
There is no swelling yet.

I got batteries that were dented too. I set them aside for a short period then kept on using them. A year later and still no atomic cloud. /DV

It looks pretty mild to me.  I think you really have to worry about damage that shorts the plates together; if that happens the battery should send up a smoke signal to let you know it's happened.

I don't know.  How much is a new battery?  It would seem that the cost of piece-of-mind would be worth a new battery. Hate to read about you burning down the shop/house/whatever.

Paul,

Our club President had a much larger 10S battery with an incident a few years ago. It just so happens that his work was next door to FMA so he took it back to them to look at. They took the battery apart and get this.....took a wooden pie crust roller and rolled out the cells flat again, they they re soldered all of the lead and balance wires and re shrunk rapped the battery. They then did some testing on the battery and said it was all good.

he stores all of his batteries in a metal fire proof safe.......two weeks or so later, the battery erupted in flame and ruined several of his batteries.

This is a long story to say the same thing, batteries are a lot cheaper that lives and a new home etc.

Dont risk it...it hurts but it is not worth it

Tim

I dropped one on the floor awhile back and I didn't really have a dent, per se, a batter check with the charger said that there was a broken connection. So something in the battery died; probably a solder joint.

Figures.

I'm gun shy of these batteries. I will replace it. What is the best way to dispose of the battery?

Randy, bad balance leads on Thunder power batteries are not uncommon. You can buy new balance leads and replace them fairly easily if you want to save the battery.
