Re: [M100] batteries...

[Chris Kmiec]

My understanding is that NiMH batteries don't leak like NiCD do, so even if
the battery itself doesn't last, the worst it will do is not work.

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.

batteries

NiMH Battery Charger FAQ - 
greenbatteries.com
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.

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 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.

I don't see why not. I'll see about putting together a kit on
