Sadly, nowhere close to 100mAh
March 1, 2019
I now own two of these "MecArmy S10" batteries which are nominally rated for 100 mAh capacity, as shown on the label. Out of curiosity, I bought a Drok USB tester that can record the charge rates and mAh accumulated during charging, since these batteries are too small to fit into typical chargers for 18650 batteries that can run a discharge and charge cycle to determine true capacity.

One of the batteries came in a MecArmy light bought here; the other ordered as a spare. I tested the discharge/recharge cycles multiple times in different minilights. One battery has a 74 mAh capacity and the other has a 30 mAh capacity.

S0 save a buck or two and buy the generic blue batteries rated at 80 mAh. In my testing of them, the are rated close to true capacity and one of them has a capacity of 99 mAh.

Solid battery

With 100 mAh, this is one of the better battery brands for its size. Not much else to really say about it.

Haven't used it yet. Bought as backup battery. Charged quickly. Has held charge so far.
