Wasabi PowerNP-FW50 Camera Battery (2-Pack) for Sony ZV-E10, Alpha a5100, a6000, a6300, a6400, a6500, Alpha a7, a7 II, a7R, a7R II, a7S, a7S II, Cyber-Shot DSC-RX10 II, RX10 III, RX10 IV and More

in the past I ordered 4 Wasabi batteries 2 for each of my cameras. The have good battery life and longevity. This last order, I didn't even think to check the batteries and two months later when I went to use them, they would not hold a charge. I contacted Wasabi directly and they immediately sent me 2 new batteries. They are charged and ready to go.I will continue to use Wasabi batteries. The battery and the customer service is excellent.

Past experience with Wasabi batteries for other devices prompted me to order these.The charge in the factory charger and work perfectly in my Sony cameras.Life is approximately the same as the genuine Sony batteries .... i.e. not that great as these cameras drain batteries quickly.Value for the money is top tier and I'd buy these batteries again.

This Review is for the Wasabi NP-FW50 Sony replacement battery for a Sony RX10 Mk III. I purchased a two pack of these not that long ago and they work fine. I've purchased other Wasabi replacement batteries in the past for a Nikon 1J5 and D7100 and both of those have held up well with pretty much equivalent run time between charges as the OEM batteries. In the case of these Sony "Infolithium" replacements I've not had many charges on them yet, but so far they have lasted as long as the OEM battery, and I expect them to hold up well.There is a Caveat though that I've seen on both of the brands of NP-FW50 (the other I've tried is a PowerExtra brand FW50) and that is that the Battery Meter on the RX-10 doesn't function accurately reflect the charge state of these batteries. What I have found is that when using the Sony Battery once the meter turns orange (replace battery) you have approx. 5 minutes of run time before the camera will shut down, but with both of the aftermarket batteries there is significant power remaining... In one case a few minutes after the low battery indication came on I just set the camera on my desk and started recording 1080p video to see how long it would continue to run and was able to record over 35 minutes of video before the camera powered down. So if this might cause an issue for you the way you use your camera you might want to pick up OEM replacement batteries.. but at Two for $20 compared to $50 for an OEM I'm quite happy.One other note on capacity.. I checked the charge milliamps from camera power down to full charge for both my OEM Sony battery (which was used as I purchased my RX10 and battery Used, but in great shape so I doubt it saw much use), the Wasabi and the PowerExtra batteries using a usb charger and usb power monitor and here's what I came up with for full charge numbers:Sony - 1973 maWasabi - 1845 maPowerextra - 1832 maNote: I'm not saying my cheap usb power monitor is accurate and that these are accurate numbers, but the take-away is that since I used the same charger and measuring equipment the numbers do show that both the Wasabi and PowerExtra batteries do have approx. the same capacity as the OEM battery that I have.So 4 of 5 stars only because of not accurately indicating remaining power on my RX10 M3.

These were purchased for an upcoming in trip that was delayed a couple of times due to Visas. Needless to say the started off pretty good then fell flat. One battery won’t take a full charge and the other can’t be charged at all. These Wasabi batteries can’t hold a candle to original Sony batteries which are reliable, long lasting and worth every penny. I wouldn’t waste my time with these….thery’re just not worth it.

These work perfectly with my Sony a6000.

Wasabi batteries for my Sony a6000 works very well for about $15.00 compadres to Sony for $58.00 or Watson for $25.00. Wasabi hold charge very well and are still working after more than a year of use.

These batteries are good for backup, but the reported percentage of charge is inconsistent. Sometimes the charge can range from 20% to 60% based on temperature and usage within a couple minutes. So It's best to make sure all of them are fully charged, before doing a photoshoot or going on a trip.

Purchased these Wasabi batteries half a year ago with a 3-year warranty. Now, both batteries have difficulty properly charging as well as exhibit dramatically shorter battery life. As smartphone cameras are so convenient, these batteries are rarely used experiencing extremely light duty taking one or two photos a day. Yes, the batteries are properly maintained and stored.

Waiting to see how Wasabi follows up on this in warranty claim.Wasabi was not only prompt to immediately respond but also very easy to work with! So refreshing!!
