Anyone know what's best to clean battery contacts/spring from alkaline poisoning? Corroded from leaking alkaline batteries
If you don't have vinegar you can use lemon juice just don't use anything with sugar in it any dilute acid will neutralize the alkaline substance. I've used light bulb dialectric grease on occasion to protect contacts a little better but it does make the battery end a little greasy.
Correct, vinegar is a rather dilute acid no need to water it down but as an acid you do need to wash it off. I sometimes finish with alcohol because it helps dry it out better. I keep forgetting I've saved batttery springs from things that I've trashed I could use to replace damaged ones. I just found a 1AA LED light that a 2010 Energizer puked in. My luck with leakalines isn't very good I've had to clean up after dozens of them in my lifetime often twice a year every so I've been spending the money on L91/92 lithium primaries to eliminate the problem.Yeah, that's pretty ugly. I doubt the strength of vinegar matters much; vinegar is pretty dilute as it is. Plenty of water afterwards. I would carefully check the resistance of the spring where it's attached to the plate - corrosion there is insidious. And I wonder why there isn't another spring? Sand or file contact surfaces, after removing the contacts from the plastic if possible. They usually just pry out, although you might have to bend a tab or unsolder a wire.
What I didn't realize until recently was that Costco alkaline AA cells have the whole body and tip as positive, and the negative is an attached disc and gasket. Thus, the leakage starts at the negative end, where the more delicate spring is.

Thanks guys vinegar did the trick, ate the corrosion right off then applied brass brush then good rinse with water. Dry....
The missing spring was broken off. Contacts are still there. Robbed a spring off a tv remote temporarily, bought a butane solder torch and stuff... but guess what got it to working
Need to do some cleaning tweaking and minor repair but not bad considering I ve never had one nor seen one of these and how it works. I m wanting to find some history on it now.
L91/92 lithium primaries, NiMH (Eneloop et al), NiCad all work and don't leak. Lipo is 3.2v so unless the device can handle it don't use it to sub for an alkaline cell.L91/92? What about aa nicad or lipo?
I hate leaking batteries and this just made me decide no more leakalines (I like that comment) for me!
