Cellular NiMH battery pack; can they be charged directly ? Answered
I have some perfectly good Nokia battery packs from useless 5165 phones (Model "bms-2s").
They are 3.6 - 3.7V NiMH and have 4 flat copper contacts which 'make' with the phones by sliding on. The Phones have matching 'teeth' and happily 'smart' charge either these or the newer LI batteries.

I want to know if it is OK to simply connect the matching output from the charger across the +/- terminals (the 2 outer ones AFAIK...) and charge them directly ?
These work great to power LEDs and I already made a 5165 LED torch, but it was a pain to do and I'd rather just use the batteries naked.
Thanks for any info !
