[NTLK] Newt about to pop!? (email)

Thanks for your reply, James.
Maybe, by any chance, there is some charging circuitry available on the web that would let me charge the battery pack outside the newton?
Of course from what I know NiCd's and NiMh's are charged simply by supplying the correct volts and amps to the cells since they're not overall as angry as LiIon's and LiPol's.
I will CC Frank Gruendel (since he knows a lot about Newt's electrical part, and, in fact, he built the battery pack, so there is no reason not to trust the pack construction, I think) and NTLK so if anyone knows if such a device is possible to build/acquire they would see this call and be able to reply.
I don't use my Newt daily, but it's very important to me, when I do.
It seems it's time to make a backup, just in case.

However, as Mr. Sciamma mentions in his post, charging battery packs internally *might* put a strain on the Newton's aging charging circuit. I can't say for sure myself and I'm afraid the above is little better than a guess on my part. :(
> With any luck, someone else on the list will have a better idea as to the exact nature of the problem you're facing; judging from your description, I'm guessing the problem you experienced is related to the battery pack itself rather than the Newton's charging circuitry. It's just that I didn't see a reply to your post and felt compelled to write something in the interests of helping to preserve your MessagePad.
