[NTLK] Was: H1000 battery and charger issue, Now: NiMH battery life?

[j]

NiMH batteries (AA variety) typically have a power output of about 2200mAH where NiCad AA’s are at about 900mAH.
So that is about 2.4 times more power output. When used in the same application (your Netwon) you will get about 2.4 times longer battery life.

For better results, find NiMH batteries with the highest mAH rating. 2500mAH is probably as high as it goes for AA’s.

With this latest discussion, I went out and purchased some NiMH batteries and a charging station.  Unfortunately, I forgot the Newton takes AA, and picked up two packages of AAA.  No biggie, since we do have some devices around the house that use AAA, I’ll keep the one set I pulled out of the packaging for those, and return the other set for a package of AAs.

I don’t use the Newton much anymore, and ANY amount of time is better than the ZERO seconds we get out of the factory battery pack, but one of the things that turned me off on the NiCad was the short span of time before they had to be thrown into the charger.  Thanks for any input.

Prior to them, I gave up on NiCd?s, ordered a very handy, little Velleman kit voltage converter, attached the biggest heat sink the hobby shop had, and hooked it to a sealed Pb-acid battery. Yeah, the rig was kinda heavy and somewhat bulky, but I was able to ignore recharging: rarely ran out of juice even if unplugged all day long. Plus I didn?t get radiated by 60 cycle.
