K&F CONCEPT NP-FZ100 2280mAH Battery and Dual Slot Charger Set for Sony A7iii, A7iv, A7C, A6700, A6600, ZV-E1, ZV-E10ii, FX3, FX30, A9, Alpha 9, Alpha 9S, A9S, A7R3, A7R4 Camera Batteries

Perfect aftermarket accessory at a fraction of the price! Works just as well as Sony OEM batteries and have the same capacity. They charge super fast on the included charger. The charger is versatile and will also charge the Sony OEM battery (as expected). Excellent quality at a fraction of the price. What's not to love?

This battery and charger combo is essential for anyone shooting heavily on Sony bodies. The dual charger is compact, charges via USB-C quickly, and the status screen makes it easy to monitor progress. The batteries hold a charge remarkably well, matching the longevity of OEM power without any compatibility errors.

Dont last quite as long as the actual sony ones but for the price of a sony battery you can buy several of these! Perfect backups!

I’ve been using the K&F NP-FZ100 2280mAh battery and dual slot charger for a few weeks now, and I’m thoroughly impressed. The batteries hold a charge exceptionally well and perform on par with the original Sony batteries in my camera. I’ve used them for extended shoots and haven’t noticed any overheating or performance issues. The dual slot charger is compact and efficient—perfect for travel. It charges both batteries simultaneously and includes a USB-C port. The build quality feels solid, and the LED indicators are clear and helpful. Overall, this is a fantastic value for the price. If you're looking for a reliable backup or replacement battery system for your Sony camera, I highly recommend this set.

Good for the price. They don't seem to last as long as the Sony brand and never seem to charge all the way despite claiming it's charged. About 89-92% charge is all I get. Otherwise...they work fine. Good enough.

One of the problems of being a photographer is the cost associated with most gear. I already sink tons of money into lenses and bodies, so I really would like to get a break on the other stuff where I can. I opted to get these batteries instead of the Sony version because the price was MUCH lower. They came charged to about 60-70%, and I popped them in the charger to get them to 100%. As normal, my A7R5 pops up a warning that 'this isn't a recognized battery', but they work great anyway. The A7R5 is a battery hog as it is, so I needed to have at least 4 extra batteries for Weddings and long sessions. These work great, and for the price, I can get more sets and have 8-10 spare batteries with me on any shoot. Doesn't seem to make sense to me to buy the official name brand batteries. One thing I did note, when you plug an official Sony battery into this charger, the charger indicator doesn't function. But if you leave it in there for a while, I do overnight, it's always 100% the next day. So, value for money, these are great.

Got 2 charges out of them and the charger stopped working. I believe the batteries are shot as well because they will not charge either. Lights on k&f charger not working and tried plugging them into the camera after charging them with no power to the camera. Bought because of the positive reviews and I guess I got a bad batch…

Great backup batteries for my Sony A6700. Battery life is pretty good and the charger lets you keep several backups.

So I got these K&F NP-FZ100 batteries and the charger for my Sony FX30. Been knowing about K&F for a bit, they're pretty popular, but this was my first time trying their batteries. First off, the batteries are solid. They last pretty long, which is dope when you're out shooting for the day. Don't gotta stress about running out of juice mid-shoot. And they fit my FX30 perfect, like they're made for it. They're new obviously but right now they feel pretty comparable to the genuine sony batteries. The charger's great too. It's got room for charging two batteries at once, which is super handy. Charges up faster than I thought it would, so that's a big plus. I can juice up both batteries and be ready to roll in no time. What I really like is the value. You get two batteries and a charger for a decent price, way less than what you'd pay for other brands. And the quality is up there, doesn't feel cheap or anything, seems to last quite long. All in all, if you're shooting with a Sony FX30 and need extra batteries, this K&F set is a great choice. Good battery life, fast charger, and won't break the bank. Totally recommend it!

Doesnt last as long as sony but its good for the price

Works great, Sony should include one as standard but it would have to be as good as this one! Charges much faster than charging in camera and charges two batteries at once. Worth the money IMHO!

Good

Most of the cost is from the batteries themselves. The charger is ok quality. It doesn't charge that fast to be honest, will take a couple hours to charge 2 of them at the same time to full. For the price it is very good, hopefully the batteries will last a long time!
