K&F Concept 2400mAh LP-E6P 2-Pack Battery and Dual Slot USB Charger Compatible with EOS R5 Mark II, R5, R62, R6, R7

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.

I must admit I have a few K&F assorted items in my photography gear, so the first thing I noticed was once again the overall (as in well made) quality as even the cardboard box these batteries and charger arrived in had a pre-shaped plastic liner as opposed to being loose in the box, like some other items I have in the past from assorted suppliers. This is a Concept twin pack of 2400mAh LP-E6P batteries coupled with a dual slot USB charger, with a LCD status screen, together with a small length lead. These had some power in them according to the status icon on my camera (Canon 5D - Mk.3) but I decided to charge them to get them up to 100%. When testing batteries the real test being their longevity, so in this case they are performing as expected as it’s ‘early days’ literally (hence the 4 star rating - so far.) but it’s their life span that matters, so take it as read they are okay unless I report back to update otherwise as and when but so far, quite happy with them.

These lithium batteries work perfectly in my Canon R5. They seem to be comparable to the OEM batteries as far as number of photos per charge, and all functions work properly, including 4K video.

It's a good backup set of a pair of batteries and dual-slot charger. Works right out of the box, charges somewhat slow but holds well enough for a third-party battery. No LED display on the batteries themselves to check current capacity, but at the least you get the LED display on the charger to base it off of.

Far cheaper and better price performing than OEM for sure.

Works perfectly as expected! This brand tends to have quality products. Its a reliable and good set of batteries. They work beautifully for my camera! There was no issue with using them on my camera. Charging was easy and fast. I had no issues with overheating or anything. This exta battery set is perfect got the price and its easy to travel around with.

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.

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.

The K&F Concept LP-E6 battery and charger set arrived neatly packed in a nicely printed box bearing the K&F branding.

In the box you get two 2400mAh LP-E6 batteries, a twin USB charger and a USB A to USB C type charging cable.

The batteries will fit multiple models in the Canon EOS range and are well finished with no rough edges or moulding flash.

The twin charger is also well constructed and features a nice clear LCD screen for information on the state of charge.

The batteries were a good fit in my EOS 5D and showed no signs of slop or of being too tight, with battery life being comparable to the original Canon batteries.

A great value set of spare/replacement batteries for the Canon EOS owner.

K&F is a reputable brand. I've been buying filters (and other stuff) from them for years. I recently picked up a used Canon 5D Mark II and figured I should pick up some additional batteries since I wasn't sure how old and/or reliable the OEM battery would be from a 15 yr old camera.

Packaging is nice. The meters on the charger are a nice touch and indicate how much time (roughly) until full. Once they stop, the battery is charge. You should remove the batteries once they are charged even if they are going to sit in your camera bag for a while. Lithium batteries don't like to be over-charged (or discharged for that matter) and they typically discharge at such a slow rate when stored.

They fit the camera perfectly and were immediately recognized without issue.

Can't speak to longevity (obviously), but assuming they are good quality batteries, I expect them to last several years without issues.
