Opus BT-C3100 v2.2 any mah gained from refresh ?


anyone out there ? who might have gained some mah form 18650 from Opus BT-C3100 v2.2 refresh mode ?

how long it took to complete ? and how much gain ?

was it temporary or a bit long lasting ?

worth the time ?

Well, as I understand it, you won’t get gains from refreshing Li-on cells, but the function works well on Nimh cells.

A set of 4 2300mAh cells I’ve had for several years in an electric corkscrew initially tested at approx 300mAh, and after a refresh cycle at 200mA, they are now back to 1900mAh or thereabouts.
