Hi Kevin,
I replaced one of mine with a NiCad a while back, but I don't think the slow trickle charge provided by the M100 will cause any damage to the NiMH you got. http://www.greenbatteries.com/nimh-battery-charger-faq/#NiCD charger for NiMH batteries NiMH Battery Charger FAQ - greenbatteries.com<http://www.greenbatteries.com/nimh-battery-charger-faq/#NiCD> www.greenbatteries.com Frequently Asked Questions about NiMH and NiCD Battery Chargers [Note: this FAQ mostly addresses questions about chargers designed for NiMH or NiCD cell batteries. And yes it was the Scotch 😉 But I like the "battery diaper" you thought up. It took over 30 years to get to the state it is in now... So in the year 2048 it should be about the same, if you put a good new battery in... But it could save a very rare (especially by then) piece of hardware some serious damage. If it is going to be open anyhow, I would spend the extra 10 minutes. Don't sweat the petty stuff...

I like this advice. Having recently realized that the NiCD batteries I ordered ended up being NiMH, I'm also pretty dubious about their quality. I'm sure it'll be fine for years to come but probably not as long as the original which was still kicking and only just showing the barest signs of leakage, not even to the motherboard yet. It actually makes me think that I should proactively assume the next owner will come across this little computer potentially long after I'm gone and it will have been in a box somewhere for years. I wonder if it might help to put a small square of thin plastic , followed by a small square of some absorbent material like cardboard or paper, between the battery and the motherboard with two tiny slits for the battery terminals. This might keep the leakage from doing any real damage somewhere down the line. I'm sure this is overthinking the problem (perhaps Scotch induced) but I like the idea of designing a solution that takes into account the inevitable failure somewhere down the line.

So, try to get Yausa or Varta or Panasonic etc, and generally pay more than $5 per batt not $2 per batt. Or at least, if you get a no-name, just be aware of that and be prepared to go back inside in a few years. Probably won't hurt the machine unless it leaks, more likely simply not work for 30 years like the original did!

I just got a 6 pack of 80mAh NiMH batteries, and just wanted to make sure before I "outfit" all 6 of my 100/102s...

I just cleaned it a bit and worked out the gunk and it started charging the battery and booting up :) yay!
