The cells have good capacity and decent current capability, but performance is a bit lower than last year. I wonder why (Maybe the cells has been in storage for some time)?

Thanks hkj. Another great. and more importantly, trustworthy review! :slight_smile:

Thank you very much for the review!

Thanks, HKJ!

Well, why do they advertise this as 840mAh battery, when in real life you couldnt get even 800mAh out of it?

Wheres the catch, much lower discharge voltage when testing in their factory?

Mostly to avoid confusion with their cheap 14500 battery that has 800mAh.

Thanks for the review HKJ

hum looks good….My ZL 14500 barely is able to hold the 500 lumens from my H52W. It keeps stepping down to about 280 lumens……Even after being full charged.

Time for some new batteries :slight_smile:

Thanks for the review HKJ!

Edit: From what vendor did you buy those cells?
