Battery rust caused by juice and firing

[BluelineVapor]

so I was rocking a pair of Samsung 25r's in my noisy cricket and I blind dripped into my bottom air flow atty. There was quite a lot of juice leakage I guess and somehow it got into the fire button and leaked onto the contact. I didn't realize and kept on using it until I replaced my batteries and saw a pretty bad burn? Or rust? On the negative end of my battery. It was caused by firing the mod and having juice between the switch and the negative end of the battery. I tried to clean it off at first but it seemed to badly damaged so I threw them away to be safe. Wondering if anyone has ever had a similar thing happen. Didn't take a picture because I didn't even want them around me anymore and threw them out without even snapping a photo.

Probably an arc burn, or pitting as a result of arcing. The black residue is a byproduct of arcing (chemical reactions between the contact and the surrounding air) and consists of a combination of nitric acid and the oxide of the base material. The only way your cell would start to rust is if the energy of the arc burned through the nickel plating of the 25R and exposed the steel cylinder to be oxidized.

+1. Likely an arc. Check the contacts in the Cricket, and surface them with sandpaper if necessary.

I don't think there really is a need to, I took apart the battery fully and cleaned it well. Once the juice was fully out of it, it functions perfectly. Mostly making this post as a PSA for people to watch out and not over drip when using the cricket.

I saw this thread and actually had a similar question. My husband recently got the Noisy Cricket and has stayed well within the amp limits of the batteries. After about 2 weeks of use he showed me one of the batteries and it has a dark-ish discoloration underneath of the wrapper. It looks like it begins at the negative end working its way about halfway up the battery. He thought maybe ejuice had gotten under the seal, but that seal is pretty flush and I do not think it is juice. Are his batteries arcing? They are new, married set. Any help would be super appreciated!

Juice underneath a wrap will make the wrap look darker in those spots. Juice will also discolor the outside metal of the battery, where the juice touches.

That said, there's no guarantee it's juice, due to multiple factors.

A good clue that juice might be the culprit is that there will be juice inside the battery compartment. It can get in through a crappily-sealed 510 if the RDA/tank leaks.

Not sure if capillary action would pull juice up through the bottom (negative side) of a battery.

A friend just threw away a couple of LG browns that she was using in her Istick 100. I was going to rewrap them for her, but the tops of both batteries were rusted.

LOL I ordered some when I ordered wraps - hairdryers send them flying across the room!

A tiny drop of Crazy glue can be a big help too.
