Have found no problems with these batteries. They work with my Canon R5 MK II OK with no limitations and have a slightly higher capacity than the battery supplied with the camera.

This product was sent to me for review as part of the Amazon Vine program. The following reflects my real-world experience using it.

It is a good-quality accessory with a robust, sleek feel that is also lightweight and compact, ideal for storing in a camera bag. Its USB-C compatibility provides flexibility when charging - you could use it with a power bank for extra portability.

I would say that the included batteries are of similar quality when compared with the official ones, and to that end, I have experienced no issues when using them with my Canon 6D. They also take around 2-3 hours to charge, though I appreciate that speeds will vary depending on the power supply used at the time.

In summary, a good value item.

Used with my Canon 5DS, the battery life is just as good as the original.
The charger with its LCD screen is super convenient for monitoring the battery status.
The whole thing stays relatively cool, even when charging multiple devices simultaneously.
The compact size is perfect for travel. A great kit for regular photographers.

Ordered these batteries just days before a spring photography trip around our small town, and they arrived just in time. As an amateur photographer juggling two Canon DSLRs, I was concerned about running out of power while capturing the melting snow landscapes. These batteries performed impressively, lasting noticeably longer than my aging original Canon battery. The dual charger proved particularly valuable - I could charge both batteries simultaneously via my laptop's USB port while editing the day's shots in our cabin. What I like most is the clear LCD display showing actual percentage rather than blinking lights, making it much easier to plan my shooting schedule. The batteries fit perfectly in both my older 60D and 6D without any connection issues. My teenage daughter who's learning photography borrowed one for her school project and commented on how much longer it lasted than her friend's original battery. While slightly heavier than Canon originals, the extra capacity is well worth it. My only minor complaint is that the batteries lack the weather sealing of Canon originals, so I'm careful about exposure to moisture. For fellow photographers balancing quality with budget, these are a practical alternative.

KF Concept products are known for their affordability, while being just as well-made (and sometimes better) than the official accessories sold at exorbitant prices by major camera brands.

This charger is no exception, as for the price of a single official battery, you get two, plus a charger that's far more sophisticated than the one usually included with the famous red brand's DSLRs and mirrorless cameras.

The charge indicator is more readable, and it can charge two batteries simultaneously and much faster: the charging time is reduced by almost 75%.

Plus, it's far from ugly, and the compact design means it will fit discreetly in your camera bag. The batteries themselves are virtually identical to the official models, but I've often noticed that compatible batteries hold their charge better. In short, it's a good (and very small) investment if you're doing extended photo sessions and no longer want to worry about running out of power mid-shoot.

These K&F Concept batteries have been a game-changer for my photography sessions. The 2400mAh capacity of each battery is impressive and allows me to shoot for much longer without worrying about running out of power.

These batteries are a game-changer! They charge quickly and last through long shoots, making them perfect for any photographer. My girlfriend loves how reliable they are—whether we’re out for a day of shooting or just capturing family moments, they never let us down. The dual USB charger is also super convenient, allowing us to charge both batteries at once.

A must-have for photographers—steady power for every click.

This LP-E6 replacement battery kit appears to be good value for Canon users wanting additional batteries. It's no secret that the original batteries are quite expensive, so my initial opinion was this represented good value for 2x batteries and a charger for the cost of one original battery.

The batteries themselves have performed well in my R6ii (even though this wasn't listed as a compatible model, but uses the same battery as the R6), allowing me to shoot in high fps/res video modes, burst modes, timelapses etc without worrying about running out of power quickly. They seem to hold a charge well, and I was able to get a good amount of shooting done on a single charge.

The included charging case brilliant, being compact, and makes it easy to charge both batteries simultaneously. It conveniently charges via USB-C which I'm pleased to see. The case also has slots for storing two SD memory cards.

The case lid closes securely enough for general use, although some might prefer a more robust latch. A small LED display on the case shows the charging status of each battery, which is helpful, though it can be quite bright in a dark room. Covering it with tape at night is a simple solution.

Overall, this battery kit offers excellent value for money. Having two reliable replacement batteries and a convenient charging case is a great addition to my photography bag.

I grabbed these as extras for my Canon and they’ve worked just fine so far. They showed a bit of charge right out of the box, but I topped them up with the little charger that comes with it. The screen makes it easy to see where you're at.

The batteries feel solid and fit just like the originals. I haven’t tested how long they last on a full shoot yet, but no problems so far. They even work with my regular Canon charger, which is super handy. For the price, I’m happy with the setup.

The batteries are beautifully packaged giving a quality feel as soon as you take them from the box. They only come lightly charged and need to given a few hours using the included charger to come up to full charge.

Appearance wise, they are identical in shape and size to the original Canon batteries but they offer improvement from the original. Although being exactly the same 7.2 volts there are some differences. They are a few grams heavier, a reflection of the fact that they have a higher capacity : 2400mAh generating 17.28 Wh compared to the original Canon batteries which have 1800 mAh giving 13 Wh.

These are clone batteries with a higher capacity than the originals. They are much better than other clone batteries which I have which can have capacities as low as 1600mAh. Also , unlike some other clone batteries, these will work in the original Canon chargers as well as the supplied usb style charger.

I am pleased with these batteries. They have given a new lease of life to my aging but competent Canon 6D and 5D Mkii cameras.
