These four AAs were used in a electric deadbolt lock for a couple of months. 2nd one is an Amazon Basics NiMh dated Dec 2017, the other three are Eneloop NiMhs which I purchased around 2012. There is no date on the Eneloops.
The Weiser deadbolt warning of low battery went off (goes off prematurely because it is set up for the 1.5V of an alkaline AA). The Eneloops took 260mahr charge but the Amazon Basics took 370 mahr charge.
Considering that all four batteries were in series in the deadbolt and subject to the exact same discharge current, does the discrepancy in the recharge currents provide any information on the batteries?
