The caption didn't say it had a micro connector. Unfortunately, I thought they all had USB-C. Beware, otherwise you will be carrying 2 chargers or 2 lanyards.

Everything is fine, no defect or anything after exploratory measurement that would be worth a negative evaluation

Professional goods. Just like the entire Fenix brand - both flashlights and batteries. (I have a great experience with multiple products of this brand. )
The shop does not state that the battery has a USB charging connector. I thought I was ordering the variant without this connector.

Battery length 70 mm (with electronic extension), to be taken into account when used in the battery compartment of the appliance. In original Fenix appliances they fit as they should (they are designed that way).
It has its own safety electronics article
No need for a classic Li-ion cell charger, just a USB cable (micro here) and a power supply
