Works well

Good battery, very long usage time!

Love these batteries and charger. The charger is slim and charges the batteries fairly quickly when hooked up to a fast charger. The batteries themselves work great with everything I've plugged them into. I've used them with various lights and they're as good as any other NP-F batteries I have. Another solid product from K&F

These are a great replacement for the Sony brand of the batteries. This battery is very versatile and useful in many devices and applications. What sets this set apart is the dual charger that it comes with. It's great to be able to throw them on the charger and let them charge rather than have to swap them out for other charge batteries.

Good product! Very good purchase! I recommend it

I'm very impressed with how well these batteries perform at this price point. It's an amazing value.

As a rule of thumb, I avoid purchasing low cost batteries from unknown brands because they can ruin your gear or even cause safety problems, so I'm so glad this is from a well known and trusted company.

K&F is a well known brand that I've trusted for years and although they're primarily known for their filters, I've used quite a few of their other accessories and I've never been let down once.

Picked up this 2-pack of NP-F970 batteries for my camera and lighting setup, and they’re exactly what I needed! These things are a solid upgrade over the smaller batteries I was using, giving me a much longer shoot time without constantly swapping or charging. Plus, they're compatible with so many different pieces of gear, which makes them super versatile. Slapped them on my camera rig, and it just kept going—barely made a dent in the power after hours of filming.
The real bonus here is using them with my lights. They power up my LED panels like champs, which is great for long shoots without access to outlets. No more stopping mid-shoot to scramble for a recharge! These batteries feel solid and come with a huge charge capacity and a nice charger, so I don’t have to worry about running out of juice when I need it most.

These batteries, designed to power a Wi-Fi video transmission receiver, seem to be well made. We'll see later.

I have been gearing up my little in-home studio, and using multiple cameras means I have multiple monitors and lights going...so I needed some more power...but I wanted it to be mobile gear as adventure season approaches (winter where I live)...so settled mostly on NP-F batteries. I tried a couple off-brand ones to save money, but that didn't go well, so when I saw K&F had this 2 batteries w/charger kit for a good price, thought I'd give it a try...

- I used one in my largest screen field monitor, and one in a setup that utilizes an iPad as a cordless monitor. Both discharged at the same rate as my most expensive batteries, and worked particularly well with the iPad, even charging it all the way up while the screen and app were in use.
- charging time took longer than discharge on the iPad setup, but I am fairly certain that is due to the brick I used...a lower power one as I wanted to see how long it would take with a standard style, unknown spec (just in cases) charging brick.
- charger is lightweight, but has nice bright led indicators, though it does not display progress...only charging and fully charged...which is fine, but a progress meter would have been nice
- build quality is nice, pretty indistinguishable from the nice NP-F's I already had

Overall these seem to be great batteries at a very affordable price, and are an excellent addition to my budget friendly studio setup. Would happily get them again, and recommend.

I was a bit iffy at first cause I know K&F does lots of lens filters, but honestly these batteries are awesome!! They hold charge perfectly! 5/5 stars
