Removing Corroded AA Battery Canon A35F

[st. paulitan]

Hey guys,

Just got a nice Cannon A35F with a corroded AA battery that I can't get out. Any ideas?

Thanks!

Pry it out with an ice pick. You can find small, inexpensive tool sets in hardware stores with four styles of picks. Just be careful you don't stab yourself.

There are toxic chemicals in alkaline batteries, including the white powder that leaks out. Wear respiratory and eye protection if there is a chance of penetrating the case. While most states in the US allow these batteries to go to landfills, CA does not.

Well, for "toxic" as in "soda", yes. When all is said and done, modern alkalines are no more toxic than laundry detergents, rust or fertilizer - they banned the more nasty components long ago. If the battery is as old as the camera, it might contain traces of cadmium catalysts and should not go into a landfill or pyrolysis (and you'd better handle it in gloves), but that is about all you have to be aware of.

Since it is 420 day, this would be the proper tool.

All kidding aside, the hemostat works wonderfully for removing stuck batteries.

also, if all else fails try moistening the battery very very very slightly with acetic acid (aka white vinegar, stop bath, ...). This will disolve and soften the white crystals. It won't help if the binding is due to the battery's expansion.
