Default SWOLLEN LIPO

How do you guys dispose of your batteries. It still works I am just afraid of it now. I tried the freezer trick and it went down but as soon as it got back to room temp it had swollen back up.
just looking for the best way to get rid of it.

Bucket of salt water. Leave it for a week and it will be fully discharged, then you can dispose of it.

You can also take it to your local fire department. At least in my area they'll take them and dispose them for us.

I discharge the battery down as low as possible w/charger, then I have a pr. of taillight bulbs soldered together and I plug the battery into that to discharge it down to nothing (lights out) and then do the salt water thingy for week and a half at least then toss in the garbage.

If there's a batteries plus store around you, they will take them.

Do the salt water thing. It's kind of a cool science experiment.

Should I post a pic? Got a battery soaking right now, watched as the battery began discharging before my eyes.

It does work and will discharge (bubbles) until the tabs are dissolved. You think it is dead because you can't read any voltage. But it isn't. Good think is that it will be difficult to short circuit.

I read somewhere that the salt/water brine creates an electrical draw between the +/- poles and that will finish off the leftover voltage. Some electrical guru should be able to verify this. Still need to discharge the battery as much as possible before the brine solution.

I've seen a youtube video of the salt brine thing where the pack still explodes when punctured, after like 3 weeks! So no, that method does not really work. Plus...anybody notice that it takes multiple weeks?


1) Get a small-ish light bulb, (I have a couple 25 watt halogens), connect it to your battery, and walk away. How long it takes depends on the wattage of the bulb...in my case it was about 30min with 2 bulbs going.

2) When you come back, and the bulb is not lit up any more, the battery will be 100% discharged. Maybe check with a volt meter to make sure? The pack will get a little warm in the process, but nothing exciting. Do it outside if you are worried...

3) Cut off battery the connector, strip back insulation, and twist wires together. Secure wires together with wire nut or electrical tape. This makes it impossible for the pack to build up any charge after you drain it.

If you do this, your pack is guaranteed 100% safe. Poke it. Stab it. Throw it through a wood chipper. Nothing is gonna happen.
