I was literally seeking an alternative, good battery for my new Sony a6700 as a backup of original Sony battery and asking questions to Amazon but having no proper answer. So, taking risk I just ordered this Wellborn NP FZ100 battery and it's worked for me. Thanks to Wellborn for providing such an alternative of half price of the original one. I've not able to fully check about backup time till now and will update my review soon. But, I think price might be lowered to some extent; so I'm giving 4 stars now. Updates: After my last travel experience, it deserves better replacement than that of original Sony battery. So, I've made right decision to purchase it. Let see for long time use experiences.

WELBORN NP-FZ100 Battery is very good for using as a spare or replacement battery for Sony cameras. I am using it on my Sony A7III camera and the performance till date is excellent.

I'm happy that the batteries work as well as the original.

First seller sent a wrong battery, these are 3000mAh, very poor quality get completely discharged after it shows 50%, when I tried to return it, they refused to return it as the battery sold was 2800mAh, kindly get my refund.

battery backup is fine for me when using it with my a77 because I always use manual focus.

It takes time to charge. Almost twice the time as Sony original battery. Plus it discharges quickly too. Almost 3x faster than sony and I have used it only for the last one month (multiple times).

Works well with my Sony A7M3. I got around 500 shots with this battery. Thats why the 4 star. Other wise no complaints as the original battery costs Rs.5500.
