Didn't work initially- outstanding customer service
This is an unusual battery that apparently sometimes ships with lithium ion 'passivation.' It tested 3.7 volts with no load, but zero volts under load. I sent seller a query. They responded same day and offered to replace it no questions, but also suggested I leave it in my device under load for an hour or more for 'discharge activation.' That worked so I canceled the free replacement. Outstanding customer service- really appreciated.

less power than other LI batteries.
AFTER passivisation burn in, brand new battery only registered 3.64V under 1 Ohm resistance. Tested against Xeno and PKCell 3.6v LI batteries, Xeno registered 3.67V, and PKCell registered 3.65V at 1 Ohm. These batteries WILL burn out faster and have less initial charge.
