Re: HP 41C replacing nicads / corroded contacts Message #2 Posted by Steve on 18 July 1999, 10:50 a.m., in response to message #1 by Mark Miller
1/3 AAA are a littel smaller than the original cells, 1/3 AA are a little too large, but you might be able to squeze them in if you were prepares to do a little work on the battery pack.
The problem with the 1/3 AAA is that they are probably a little lower in capacity than the originals, so the charge current is even more excessive. It just means that you don't leave it on charge for too long. (as for how long, you can measure that with a thermometer)
The larger packs use sub-C size nicads. These are readily available and are now of significantly higher capacity than the ones originally used.
The battery terminal is not too hard to repair if it's not too badly corroded. There are several guides on how to do this floating around. It's apparantly not too hard. I've not had to do it, so I can't offer advice.
