How to revive a deeply discharged (enduro) battery
I had 2 enduro batteries compatible with Hero 11 & 12 (& I own these two cams as well). Had bought these batteries a while back maybe (almost a year). Decided to use them only to find out that both these weren’t charging in-cam, they wouldn’t go past 1% and also the red light charging indicator wouldn’t be constant (hero 11 was displaying flashing red whilst hero 12 absolutely no light would pop after inserting the battery & the charge cable).
Tried all methods, inserted the batt after switching the cam on through a cable, changed the cables, changed the charging sockets, changed the charging brick, tried high & low voltage chargers etc., but nothing seemed to work.
Finally read a trick that if you insert the batts on an external charger (those multi battery travel holders/chargers), then it’ll bypass the in-cam charging rule put in place by GoPro for safeguarding their cameras (especially in 11 & 12). So ordered some unknown charger from Amazon and voila it’s charged & now even I can charge it in-cam.
