Samsung 35E specs here (not sure if this specsheet is the latest revision, as it’s not from Samsung website themselves)
HKJ tested and reviewed them here:
Note however, that this offer is the button-top version (original Samsung has only flat-top version), so most likely, the reseller added a ‘button-top’ to make them compatible with some flashlights that only work with button-top cells.
Interesting note is that the specsheet specifically indicates ‘for cycle life’, it has to be charged at 1.02A only; and if charged at 2.0A, then it is ‘not for cycle life’ (it’s detrimental to cycle life?)
Discharged to 2.65v cut-off voltage (I notice for many >3000mAh branded 18650s, the cut-off voltage is rated at 2.50v)
