I don't know much if anything about this size battery, other then it is really small the size of a AAA. I was going to suggest the Pila IBC charger, but read this in the manual:
1. What size cells does it charge and what doesn't it charge?
RCR123, *10440, 14500, 14670, 16340, 17500, 17670, 18500, 14500 up to 18650. It can handle cells up through 18mm diameter at least and 65-68mm in length, so 18650 on the large end.
*Don't run 10440 cells below 3.8 volts resting. The Pila IBC has a maximum charge rate of 600 mA, and the 10440 cells are about 320 mAh, so approaching 2C on a fully empty cell, but if the cell is around half full, the voltage will quickly climb to 4.2 volts and then the current will quickly drop off. Dont charge an empty (3.3 volts resting) 10440 cell with it, but if it is closer to half empty, it is pushing things, but still will be reasonably safe. The 10440 cell suffer a loss of cycle life by doing this, but that may be acceptable to some.

In the Pila charger manual, this 10440 battery type is hi-lited in red text, and the NOTE ABOVE. Since this $50.00 charger has no problem with the other types or special notes, I would begin to wonder about why this type is different and NEEDS special attention? While it is always possible to get a bad batch of anything, it would be very odd to have that many be "bad". Looked at the thread quickly, did not note the brand of the battery, or the charger that was used, and how many times they were charged. If you must use this size battery, you might try the AW batteries, or even the more expensive Pila brand. Wish you the best!
