I hope the batteries retain the charge well enough.

Bought these for my Sony A1 and these batteries works as expected. Recommended.

Only use a couple time and two month later it start having issues with voltage. Email seller asked for advide they relied 3 days later asking for proof of purchase and photo/video of issues, sent in....and never heard them again. STAY OUT FROM THIS SELLER

I did some cursory research and these batteries and charger are manufactured by a Chinese company that claims it has ten years of experience creating batteries and charging systems for power tools, cameras and more (magolin.com). I have no reason to doubt them.Initial feelings:1) It's nice to have a charger that holds three batteries2) It's also a nice touch that you can connect the charger to power using a USB mini plug as well as the newer USB-C. So you have options.3) It also seems to be compatible with Sony, in that I don't get a warning on my Alpha cameras when I first fire them up that says, in effect, "Are you SURE you want to use this off-brand battery? If so, we need you to click YES so we can be let off the hook, in case it bursts into flames."4) The initial battery life is pretty impressive. I turned on my Sony ZV-E1, hit video record and let 'er run. The freshly-charged Magolin battery powered that recording for an hour and forty-five minutes. That's pretty good.Things I don't know:1) I don't know how this battery will fair long-term. It's always a mystery when you go with after market batteries. For example, Magolin charges $58.99 for these three batteries AND a three-battery charger. While Sony, the company that makes my camera, charges $78 for ONE battery. And no charger! Are the Sony batteries THAT much better? Or are these Magolin batteries so much worse? The Sony battery is listed at having a capacity of 2280mAh, while the Magolin lists 2500 mAh. That's better, right. Or...no?You've heard the expression, "If it seems too good to be true, it isn't true." So what am I missing about Magolin batteries?Only time will tell. (Or not.) In the meantime, I'll just enjoy these affordable batteries that give my Sony camera a long running time on video.

Having been a Sony shooter for a few years now, I have assembled a decent collection of batteries from different brands. I finally decided to put them all to the test and see just how the battery life compares between brands.For my test, I started with a freshly charged 100% full battery and recorded exactly 30 minutes of 4K video on my Sony A7IV (firmware 2.0) set up on a tripod in manual focus mode, SLOG-3, XAVC-S, 10bit 4:2:2. All settings remained exactly the same while testing all of the batteries.Although the Magolin battery finished in the middle of the pack, it wasn't far behind the Sony batteries. Considering that you get a 3-port charger and 3 batteries for under $60 (at the time of this review), this product is an incredible value for the price.Here are my results:1st -- Ulanzi (Rating: 16.2Wh, 3 months old) 79% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 2 Hours and 23 Minutes1st -- Neewer (Rating: 16.4Wh, 1 year old) 79% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 2 Hours and 23 Minutes3rd -- Sony (Rating: 16.4Wh, 1 year old) 75% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 2 Hours and 00 Minutes4th -- Sony (Rating: 16.4Wh, 3 years old) 73% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 1 Hour and 51 Minutes (Battery No Longer Holds a Charge and Dies after Several Days; Note: In 16 years as a photographer/videographer this was the first battery to ever fail on me)5th -- Magolin (Rating: 18 Wh, 1 month old) 71% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 1 Hour and 43 Minutes6th -- Kastar (Rating: 16.4 Wh, 2 months old) 63% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 1 Hour and 21 Minutes7th -- RavPower (Rating: 14.8Wh, 3 years old) 58% Battery Remaining after 30 Minutes of 4K Recording; Potential Recording Time 1 Hour and 11 Minutes (Battery Warning Triggered on Camera, Battery Percent Number Hidden)

I have owned aftermarket batteries for many devices over the years... and have never been impressed with the useful battery life for any of them. At this point - I just consider the cost versus the useful life... and keep that in mind when I use one, as I know they won't last as long.I recently purchased a Sony ZV-E1 along with an extra Sony battery. As you are probably aware - those Sony batteries aren't cheap. When I saw this set of three with a charger included - for a lower purchase price - I felt I needed to try them out.I really love the compact size of the charger! It's about as small in form factor as can be... and the fact that I don't need to carry any extra adapters or power cords to use it makes me smile. I simply grab one of my USB-C power cords that I use to charge a phone or other device - and plug it in. Easy peasy.I've only tried one battery so far - so I'll update this review if circumstances warrant. I plugged that battery into the camera and it fired right up without complaint. Not all cameras will accept non-OEM batteries - but my ZV-E1 accepted this one.According to the labels, these batteries have a little more capacity than OEM. I turned my camera on and left it running and got around two hours out of it... which is better than I expected. Perhaps if I had given it a workout it would have expired sooner - but in any event I am satisfied with the battery life and recommend them!

This kit is a must have for anybody who owns a NP-FZ100 powered camera. It includes 3 batteries and a charger that will let you charge all of them at the same time. That means no more plugging the camera to the wall in order to charge the battery, total win!
