Hi Jim, Maybe this is specific to europe but NiCds are hard to come by here,
they are prohibited since 2008 And even more prohibited since 2017 ( they also
exclude medical equipment ) I used to source them in ex-ussr countries but even
there they are hard to come by nowadays, quite expensive, and usually new old
stock from 10+ years ago which hardly qualifies as renewing your battery pack,
even if it's usually better than the 40+ years batteries. On top of that they
are usually 700mAh, which isn't much by today's standards I'll be trying to
shove 2400mAh NiMH in my CE150, the question remains, do I keep the NiCd
trickle charge (many people did and seem to stil be alive) or do I go the extra
mile and use a proper NiMh charger ( that'll blink when batteries are full and
stop the charge ) You could also argue wether or not a $1 nimh charger from
Aliexpress does any good to my safety. I'm surprised "replacing nicd with
modern equivalents" doesn't seem to have much attention Le 2022-12-22 16:52,

equivalent ) and it's not the first time I face the same problem ; how to
replace NiCD batteries. In the past what I did is actually order new NiCd ( you
can still find them here in Europe, well actually out of europe but in eastern
countries close to europe ) However they are at best NOS nowadays, that does
"work" enough for moderate use (I've done that on vintage laptops) This time
I'd like to go a bit beyond that and replace the NiCd with modern NiMH (the
plotter coils and motors will benefit the extra power) However the trickle
chagre of NiCd applied to NiMH will either kill my batteries or kill me in a
house fire. I see small $1 NiMH 5S charging boards on Aliexpress, I thought I
might use that, try to shove it it the CE150 (or other devcies with the same
problem) TL-DR : Before I re invent the wheel here ; Has anyone developed a
