4 Pack NP-F970 Batteries and 4-Channel Charger for Sony NP F750, F550, F570 and Sony CCD-SC55, TR516, TR716, TR818, TR910, TR917

These are wonderful! At a full charge they last at least 5 hours. Haven’t neeeded them for longer, but I would imagine they could last even longer. The set up is perfect. One plug to charge them all. Takes some time to charge, so I throw them on the charger over night. So beats having to use electric outlets when in remote locations.

If you need spare batteries with a charger with a deal this is it. I used these for my RGB LED panels

I say these batteries are the Best and the Worst. I have 16 of these batteries and use them most of the time. But... Out of these 16 batteries 4 have starting to leak and I just bought them in December 2023. I can't say I don't recommend these batteries, because they work fine for the money. And they fit everything I have from all my photo lighting to my portable 7" video monitors. I wish they had a better warranty, because I would like to have these replaced.So... If you buy these batteries keep an eye on them. If you see them start to leak, make sure you replace them before your return time is up. Again, the other 12 batteries are still working great.

2 of the battery last over 5hrs 30m on my GVM led 480ls.Love them

Doesn’t seem to charge all batteries at the same time.

If you're going to use it keep it. Don't charge your batteries and leave it alone because it gets dangerously hot. I'm still playing around with if I need to charge one or two batteries at a time but I was trying to charge four and I unplugged everything but I guess it seems like it was going to burn my house down.*Seller reached out to offer a full refund.
