What should I do about a battery that is leaking white stuff into my favorite little clock?

Asked by skfinkel (13478points) September 16th, 2010

I noticed the clock wasn’t moving, and then turned it over to see the battery is gone (even with a date of March 2011). It seems hard to remove because of the hardened white stuff (acid?) from the battery. What to do? I love this little clock….can I just try and force it out?

I would make a paste with baking soda and water. Use that to try and break down the white stuff (use sparingly). The white stuff is battery acid and it is best to avoid touching it. Rubber gloves are your friend.

Well, I made a paste with baking soda, put on rubber gloves (which I never would have done), and then pried the old battery out. Cleaned it out with baking soda, put a new battery in, and good as new. Thanks for the advice, @johnpowell.

Get something with a small sharp tip and gently scrape it off. I had a flashlight that wouldn’t work because acid had leaked onto it and once I scaped it off and put fresh batteries, it was working again.
Hope it works for you.

It’s corrosion. <—This link goes to advice.

Hey now, hey now hey now, sing this corrosion to me…

Sounds like you already solved the problem. I’ve dealt with this situation many times. After cleaning out the gunk, use an emery board to restore the bare metal contact points where the new battery goes. Most of the time the device can be restored with no real damage.
