Puffy Battery

One of my 3.7V 800mAh LiPo's has gotten puffy like a balloon. What causes this and can it still be used? It is not old and has been charged maybe 3 times. Thanks.
 
I have always heard that is bad, even dangerous. I have never taken a chance with those, always thrown them away.
As I was told when asking if they were safe to use is "the safe answer is no".

Yeah, thought so. Haven't been using it, so guess i'll chunk it and order some extras again. Thanks
 
Check what the battery's voltage is right off the charger with a multimeter. Might be a faulty charger that is overcharging and may ruin all of them.
 
"Do yourself a favor get a $10 multimeter."
Don't have one yet.
Guess ya right tho, second, 600mAh battery puffing too.
Bought a 4 batt+charger setup from the slow boat from chiner, probably the prob.
 
Dang. If it's swelled up chunck as far as you can!! Punctured one with a needle and it exploded like fireworks. Smoked up the house and stinks awful bad. Venting with a blower now! Hope not a health hazard.
 
Batteries typically puff not so much from overcharging, but when discharged below 3 amps. Don't fly until your craft loses power, that means your battery is drained too far.
 
With the toy quads I got, in my experience when they drop out of the sky, a quick check shows the battery to be at ~ 3.6-3.8V. I guess if you leave it sitting there after a flight with the lights blinking and forget about it can drop too low.

What do you have?

Thanks for the info, that's what I've been doing! Once they puff are they any good?

I have a Syma X5sw-1 with 3.7 800mAh and 600mAh batteries. I guess I am flying too long after lights blink. Good flights can do that I guess. Thanks
P.S. My $12 mulimeter is on the way from Walmart.
 
Dang, 4 of my batteries have died out since yesterday. Have more ordered, guess I need to cut back on flight time per battery. Especially in this 98 degree heat.
 
Time your flights that you've been doing once, then cut back by 1 minute. Your batteries will thank you.
 
is there an approved way of disposing of these ? i've got one that's down to 3 minutes fly time now, time to replace
 
You can take it to any large electronics store like Best Buy, they have a battery disposal bin. Or if you want to do it your self, mix up a pail of salt water and throw the battery in it and leave for a few days, then it's good to throw in the trash.
