... or just charge them as dumb old way using slow and low constant current ?
As I'm aware, cmiiw, the peak detect just can be effective only in single cell charging, and if > 1 cells in series, it will not be reliable mechanism to terminate the charge.
Any thought ?
I am aware of 9V Lithium primary cell, its just just looking for 9V Alkaline alternative.
Random image of 8.4 V NiMh battery grabbed from Google.
