Nice batteries but overstated capacity and voltage!
These batteries are slightly longer in size due to the protection circuit built into them to protect from over charge, over discharge, over current and short circuit. The plastic shell case arrived broken during the shipment but the batteries seem to be fine.I ran a full cycle test on them and the capacity of 2500mAh rating is greatly overstated as you can see on each battery, one being 1830mAh and another 1782mAh. The Voltage is 4.20V not 4.35V. Considering that they are made in Japan they should hold up well over time but I think they are overpriced at $17 a piece.

Great Rechargeable Replacement for Two CR123A Batteries!
Reviewed in the United States on April 16, 2023
This two pack of 16650 rechargeable batteries comes in a bag with a hard plastic case inside. Basic instructions and safety tips are on a card inside the bag. The case will hold these two batteries and can also hold four CR123A batteries. The 16650 is a perfect replacement for two CR123A batteries. One 16650 fit perfectly in my Surefire E2DL flashlight and the light intensity is the same as with the OEM brand 123As. Having rechargeable batteries is great because I don't need to worry about usage. When they run out they are easy to recharge. This set has a raised bump on the positive end.Reviewed in the United States on April 16, 2023

These Li-Ion batteries are basically like the more common 18650 but have a diameter 2mm smaller, which can be convenient for some smaller flashlights that were not designed for 18650 batteries. I tried them in an older flashlight tube designed for CR123 batteries and they fit, although they're not a drop in replacement for two CR123 batteries because of differing voltages. Note that 16650 refers to the diameter of the cylindrical cell (16mm) and the length of the cell (650mm).
I only got ~1900-1950mAh when I tested them by fully draining them on a flashlight and then recharging them using an intelligent charger that keeps track of exactly how many mAh it puts into the batteries. So according to the charger these 16650 batteries are only ~75% of the advertised 2500mAh (1880/2500=75% of advertised capacity & 1948/2500=78% of the advertised capacity). Looking at the other reviews I see that at least two other people tested the mAh of theirs and got slightly worse results than I did (e.g. 1782mAh, 1830mAh, 1800mAh, 1809mAh, 1817mAh, 1840mAh ) so I am going to assume that these batteries are much closer to 1800-2000mAh than to 2500mAh
