Neewer 2 Pieces 6600mAh Replacement Li-ion Battery for Sony NP-F970 NP-F960 NP-F975 NP-F570 and LCD Dual Charger, Fit for Neewer CN160 FW568 F100 F200 FW700 and Other LED Video Light or Monitor

So far I'm impressed with this charger and batteries. I JUST received them yesterday and I already put it through a few tests. As I continue to use them and am able to test its longevity, I will update this review. (I know how important it is to know if these are a good quality product.)Out of the package, the batteries come 50% charged which is not a problem.The charger itself has a trickle-charge setting (L) or a quick charge setting (H) which is toggled by a simple button. Package came with no instructions; it's not exactly obvious to notice this function but it doesn't take a genius to figure it out, either. I have some other smaller, older batteries and all but one charged up fine. The one that didn't could only reach a max charge of 90% which is understandable given how old and how much it's been used.As for the 6600mAH batteries that came with the bundle, one charged up fine while the other seemed to hang at 30% charge for hours (overnight for at least 6 hours). I changed slots several times and waited each time but still no change. I switched it to the low-charge setting and waited and before long, it finally read 40%. (I was about to contact support for a bogus battery.) As soon as it read 40%, I switched it to the quick-charge setting and in a couple hours, I was able to see the charge steadily rise til it reached 100%. So far, so good, but I will still continue to monitor the performance of that one odd battery. Will update the review if there is a problem with it later.TESTING THE CHARGE: I purchased these along with a pair of 30W Neewer 480 LEDs light panels. On my initial test, I put the 50% charged batteries on the lights and left it on full illumination until it drained the batteries. I threw them on the charger and one charged back to 100% in a few hours while the other one had that charging issue (see paragraph above). Once I was finally able to get both batteries to full charge, I did a long burn on the Neewer lights. I put one battery on each light and turned the lights on all the way to max and started a timer. Each light finally went out after 2 hours, to the hour. One shut off at about 1 hour, 58 minutes, the other went out 3 minutes later just barely over 2 hours.I am quite impressed with its initial performance. As I continue to test these, if they begin to disappoint, I will update this review. But for now, it's 5-stars for value and battery life. Longevity rating is still TBA.

Lost my original Sony batteries and charger on a shoot (bottom of the ocean) so picked this up and was very surprised. Batteries are of high quality and charge quickly. Best part is they have long life during shoots. Almost as good as the original Sony. Charger is easy to use and has a nice LED readout. Batteries also attach to Sony camera easily-another knock-off battery I purchased didn't. Highly recommended from this filmmaker!

I have the new Sony 7s III camera. These batteries work well in the camera. They are a phenomenal value and are well-made.One thing to know: Sony made it more difficult to replace their batteries with knock-offs like this one. Upon start-up of the camera, about 30 seconds into using your camera, a warning notice will come up. It tries to scare you by saying that the camera's operation may be compromised by using the battery. (I have had absolutely no problems.) You need to hit "OK" and then can get started. If you are in a hurry to get a shot, this is a real pain and you can even lose a good opportunity over it.

This charger is great, the lcd screen is a nice touch and for the price it can’t be beat. You can find cheaper options but with my experience of those chargers, is that they often shorten out. The batteries they include with the charger are solid and hold their charge. I’d recommend this bundle to anyone looking to charge NP-F770 or similar batteries.

Thing is a beast.Stocky but clearly good tech.On the large side, and that's a Good thing.It seems like it will last a long time.Charging takes a while, because the batteries are HUGE.Price point is just amazing.To those complaining about how parts come off, I don't dislike this. They snap back easily, and this offers flexibility where a different product might just break.

There's nothing like having a place to charge two batteries at the same time rather than searching for a plug for each charger around the house.In terms of performance, the L setting takes for ever to charge NW-F970 batteries. The H setting is much faster but still takes quite a bit of course since these batteries are THICC.Speaking of batteries, I'm glad this kit includes them. It saves me the hassle of searching for some. They work well so far and I use them on an LED light and a camera Monitor as well.It's also convenient that it has a USB charger.

Works awesome with zoom f6 field recorder

Gets the job done. I like the LED screen it has and how it shows the percentages of each battery being charged.
