What is the quality of the Fujifilm NP-W126S compatible battery? fujirumors.com– JJC is offering a practical (and cheap) dual USB battery charger for Fujifilm NP-W126/S batteries fujirumors.com– TESTED: Third Party Fuji Batteries? “Inflated capacity values. Some batteries almost Fraud!”… and the Winner is…?

Personally I have a couple of Fujifilm OEM batteries, but I am also satisfied with my Patona batteries (I think they are Watson branded in North America). However, even with a genuinely equivalent capacity to the OEM battery, there may still be differences in power delivery rate, self-discharge rate, and ultimate rate of decline in battery’s SoH (State of Health).The original Fujifilm’s batteries for X system camera are expensive. That’s the reason why there are so many alternatives available, but it also makes the choice of the right one tough. They not only vary in price and capacity, but some 3rd party batteries can even swell in camera and potentially damage it. This article tries to help with the right choice due to extensive testing of capacities and heat characteristics of several available brands. NP-W126S Japan, China : 2,412 MHz–2,472 MHz (13 channels) * Other countries : 2,412 MHz–2,462 MHz (11 channels) My old original NP-W126 currently, after several years of usage, has roughly 1100 mAh, while it had >1200 mAh when new. Lower quality batteries can show more significant aging, the DSTE battery is already almost unusable. Conclusion

Well it's nice to know I can buy one of these more expensive NP-W126S batteries and use it in my X-E2 with absolutely zero gain in performance. Apparently the cheapest aftermarket batteries fail pretty bad, but fortunately many brands offer pretty solid competitors to the original batteries. They often have almost the same capacities and also heat management under a heavy load seems to be alright.
