--- on the heady topic of " replacing batteries in Norelco shaver"

JY From: Jim Yanik .

Anyone ever replace batteries in a Norelco (or other brand) shaver?
Anything I should be aware of or watch out for? Seems like it should
be a pretty straight forward procedure.

TIA



JY NiMH cells have a more complicated charge requirement than NiCd.
JY Unless you plan on designing a new charger,you should only replace
JY with NiCd cells similar to what you removed.


Riding my bike I found a cellphone flattened by traffic on the side of
the road. Its Li-ion battery seemed undamaged and it took a controlled
charge okay. I was thinking of replacing the 2 sub-C nicads in a hand
driver with it, as the Li-ion cell has a 1,000mA/hr spec on the label.
It seems impossible for such a small battery (2"x1.5x1/4"thick). There
are 3 contacts on the cell, beneath is a pcb with surface mount IC's.
One terminal is labelled TH, what is it, thermal monitor?

.... That was a fascinating period of time for electronics
