Damaged AA Energizer Ultimate Lithium, are they ok to use/test?

I bought these OEM Energizer Ultimate Lithium's from eBay, just now I was going to discharge 2 and check the capacity out of curiosity.

Then I noticed 2 of them are damaged, one has 3 dents around the base and the other has nearly like a puncture (doesn't go through though) mark on the bottom.

Would they be safe to discharge or should they be thrown out?

Also Ill send these pictures to the seller, maybe Ill get a refund for the price of 2.

ABSOLUTELY NOT SAFE. DO NOT USE/CHARGE THESE.

Ok thanks, thought it was a good idea to check fist.

Ill just hold on to them for now until I find out what the seller will do about them.

Ill discharge 2 of the good ones instead to check capacity and voltage.

I may be accused of being alarmist, but I am really just overly cautious. Put those things far away from anything that might burn. Outside on pavement would be a good choice. I don't suggest keeping those damaged cells anywhere inside of your home. Li-Ion is really pretty safe as long as it's treated with respect, and those cells have not been treated with respect. They're dangerous.

Be Safe.

Just tested 2

500mA discharge = 2990mAh

1000mA discharge = 2912mAh

The seem legit to me. Now I only have 16 left though.

Hey, these are not Li-Ion, they’re Li/FeS2. :stuck_out_tongue:

Ah, Didn't even realize that - Saw the word lithium, Saw the physical damage, and started typing :)

Do not use those. They can explode and burn. They contain pure elemental lithium. If that comes in contact with air(water in air) it reacts with that producing hydrogen and heat. Depending on the conditions it can cause a sizeable explosion. I have taken them apart and in controlled conditions let them react and it caused a small fire.
