Using NiMH cells should eliminate any problem, as they (generally)
tolerate rapid charging. I used regular NiMH cells for a Polaroid #365
electronic flash, and the #363 rapid charger handles them fine, even
though it was designed for rapid-charge nicads.

I'd be cautious of the charger meeting the requirements of 2300 mAh
cells without it struggling.

The charger doesn't "know" the cell's capacity. It just pumps current into
it. The better class of chargers shuts off when a particular cell voltage
(and/or some other condition) has been reached.


Been dealing with these issues for many years in battery packs for my
handy talkies. I have a spare 7.2v 1400 mAh pack for my Vertex FT-60.
It won't charge slow but drop it in the rapid charger and it charges just
fine. Doesn't make much sense. I own a Maha multi charger that uses
a temp probe placed on the cells to help decide the charge.

I have two MAHA C9000 chargers. I wish they'd been available 40 years ago.
