BM Premium 2 Pack of NP-FZ100 Batteries and Dual Bay Charger for Sony Alpha 1, FX3, a7C, a7S III, a6600, a7R IV, A7RIII, A7R3, a7 III, a7 IV, Sony Alpha A9, Alpha a9 II, Alpha 9R, A9R, Alpha 9S Camera

The batteries are just perfect for my camera. Two batteries with a charger and the cable but not the cube. Took about 3.5 hrs to charge fully. So far, I recommend it. I will go out to shoot some waves tomorrow and I'll see how long the last.

Good replacement for Sony charger. I had lost my original charger , ordered this one for replacement. So far no issues, charges two batteries at a time. Good addition to my camera gear. Highly recommended.

These batteries are very powerful and reliable for the sony ecosystem. Fully charged shooting at 4k you can expect to get around 1 hour of record time. They take about 2 hours to charge. So hot swapping will not be a problem. I have hot swapped theses batteries for almost 8 hours of steady shooting

Works as advertised. Great price, good quality

Just got these batteries. They fit perfectly. Can't speak about how long they'll hold a charge or how long it takes to charge, but I'm sure it will be adequate. Most importantly, I now have spare batteries for when I travel. And at the good price!

I bought A7C which had a sony original battery, and at the same time I bought these backup batteries. These outlasted sony. It also performs great in camera. May be I got a bad piece of the original sony battery. But it is surprising.

You need this is you charge multiple batteries.

Great dual charger
