A rechargeable flashlight battery is capable of delivering 90 mA for about 12 h.
How much charge can it release at that rate?
If its terminal voltage is 1.5 V, how much energy can the battery deliver?
Probably it would be possible, if you will charge it on 1.5v, but some times because of high voltage battery will be damage, I had faced that when I charge my flashlight battery with high voltage which I recently got through Olight USA free shipping codes, I just wanted to charge early, so don’t charge on high voltage, just on normal capacity voltage which are given by the battery volt.
