Kastar Battery 2X for Fujifilm NP-50 BC-50 BC-45W Fuji FinePix F50FD F60FD F70EXR F80EXR F100FD F200EXR F300EXR F500EXR F600EXR F770EXR F800EXR F900EXR Real 3D X20 XF1 XP100 XP150 XP160 XP170 XP200

Price was great and quality seems good. These batteries were well packaged and even included both a mini-instruction leaflet and a card with contact info in case there were any problems. Many of these off-brand batteries arrive with nothing, just the batteries, so the quality of the packaging was a nice surprise.The batteries themselves seem to be well made and charged quickly and seem to be working fine. As I get more experience I will come back and update if I find any issues. So far, they seem excellent. One of the least inexpensive sets as well. I have tried several others and these seem by far the best.

Excellent replacement for Kodak Zi8 video camera.I have since moved on to GoPro cameras for my mobile video work, but my daughters found the Zi8 in my desk during our last move and asked if they could use it for their miniature movies, as they were tired of the very low resolution of their old camera. The Zi8's original battery had been left unmaintained for years and had gone cold and dead.These Kastar batteries arrived around 90% charged, and over the first couple charges expanded their capacity, as quality LiION batteries should. Easily as good as the original cell supplied by Kodak. And thanks to them, by girl's YouTube efforts are now HD.

Charged both batteries when received; one charged ok but the second one has a fault and will not charge fully. Have not yet contacted the seller for replacement but expect them to replace it at no charge.

I can't say whether the 1400mAh claim is justified, but the batteries work well. I've used them in a Fujifilm W3, a Fujifilm F770EXR, and a Pentax Q7. All of these cameras should probably have been designed for a bigger battery, so having a couple of charged extras in my pockets when I'm out shooting gives some peace of mind. At the price, the Kastar batteries are great for this purpose.

The product came packaged in excellent condition. However the batteries only provided an additional 5 minutes (1hr 35min continuous recording) of recording time to my camera Kodak play sport zx3 (6 years old) when compared to my old original battery. My camera battery indicator started to show less than full charge after 2-3 days after being charged. I was not confident that it would hold a charge too long after being chargerd.

I used one of then once during the summer of 2017 on my waterproof camera, and everything was fine (just a recharge at the end of the trip). So at this spring break, I try to recharge it and I never could (flashing yellow light on the original Fuji charger), I only managed to take few photos during my trip this week (both batteries are depleted, even the brand new one).

Inexpensive and holds a great charge.

I ordered 2 sets of 2 batteries. Three of them worked and and one would not charge, so one set had to be returned. When they work, they seem to work just as well as the factory batteries, and they are much lower in cost.
