This battery is well-made and works perfectly on my Canon 5D3. This battery lasts noticeably longer than the old Canon battery on a single charge, which is understandable as the old battery has been used for over 10 years. It was quite fast to recharge but I didn't time it. I checked after 3 hours of charging and it was already fully charged. I like this battery because it can be recharged through a USB-C port so I don't need to bring the battery charger with me during travel. This battery is priced at £36.99 at the time of review, which I think is reasonable considering the build quality and USB-C charging port design. I would highly recommend this battery if you're looking for an affordable replacement.

The benefits of extra batteries is a must, but not at the price original ones cost!, these are the perfect alternatives, not only can they hold their charge longer than most, they are dual charging having the versatility of usb or adapter charging! Very handy, plus the added bonus of not triggering the Sony software for being third party items, definitely recommend, worth the money 100%

Super batteries that hold charge and are compatible with Canon

I cannot speak on durability, longevity or performance even. What I can confirm is that it works very well in a Sony A7IV running firmware 3.01 with no battery warning.

K&F do have a relatively decent reputation, so I took punt on these. the plan was to confirm it was fully compatible with the Sony camera, in my case the A7IV and to return it withing return window if not. I am glad to say these are keepers for now.

Great performance, easy and quick charging, great value for money, highly recommend.

This a good battery and seemed to charge in a similar time frame my to original battery. I had no problems using it and found it gave me a very similar performance to the genuine item. Just having a usb-c charging port is a fantastic idea - who doesn’t have a usb-c nowadays? More than happy to recommend this product.

I'm "Canon" born and bred. Over the years, I've bought the Canon EOS 5Dmk1, 5Dmk2, 5DSr and 5Dmk4 all new and all from New York. Each time I bought a set of two, new official Canon batteries every time I bought each camera as I always use the associated battery grips for each camera. Now, some of those Canon batteries are getting tired and at some point I will buy an 'R' camera so wanted to buy descent, high power, replacement batteries. I've never really been a 3rd party equipment buyer, always opting to buy OEM gear (Canon) so this was the first time I've bought a 3rd party battery. I've heard so many horror stories of cheap Chinese rip-off versions of LP-6(+N+H) batteries, but these K&F batteries are superb! What I thought wasn't clear in the Amazon advert was, apart from charging via the USB cables, could these batteries be recharged in the official Canon charger and can they be recharged in a good quality 3rd party charger? YES, they can and they interface and operate/register with each of the listed cameras above as though you were using the official Canon batteries. I have no hesitation in recommending these cells. They are robust, reliable so-far, they don't get too warm when charging and they seem a very good quality product. They're not dirt-cheap for 3rd party batteries, but you get more than what you pay for with these......they are in a different league to other 3rd party batteries you find available and as such, they offer excellent value.

Battery charged up in a similar time to the genuine Canon battery and was recognised by the camera with no conflict. Gives similar performance to the genuine item. Having the usb charging socket is a fantastic idea. I have had several K&F items in the past and they have all been excellent quality and work well

Competitively priced alternative to the official batteries.

Being able to charge it with a cable adds flexibility.

I like the white colour.

Charged quickly.
