LP-E17 New Upgraded Battery and Rapid Dual USB Charger

Worked just as the factory battery in my Canon T7i. I ordered mine March 18th 2018 and I have no problems using them, and the charger is much nicer than the OEM Cannon charger. I don't receive any errors using the batteries and I have full factory function including the battery percentage on screen. Battery life is very good so I have not had too many charging cycles on them but so far so good and seems about the same as the OEM battery which I also don't have many charging cycles on. The USB charger is extremely welcome, it is much smaller than the OEM Cannon charger and much easier to use on the road or at home charging one or 2 batteries. Even if the life span of the batteries deteriorates over time the charger is easily worth the price of the set which is a fraction fo that of a single OEM battery. Definitely worth the price for me.

These batteries work really well and I love that you can charge both at once. I use these strictly for astrophotography as seen in the photo above. If that’s an interest see Reddit r/askastrophotography It shows the battery life on my camera but it’s not entirely accurate. It seems like the batteries probably last about 2/3 as long as a legit canon battery. I shoot long exposure photos of deep space objects so I leave the camera unattended for long periods of time, but it seemed like the camera went from displaying a full battery to all of the sudden dead. My point is the battery meter probably isn’t that accurate for these batteries but for the value these are a solid buy and you can have multiple batteries charging at once. They may not hold as much of a charge as a canon, but I mean... how hard is it to swap out a battery? Edit: the battery loss seems to be due to low temperature.

Works well with Canon rebel t6i. It is nice to have two extra batteries and you can charge one or both at the same time so you do not have to worry about charging one and then the other at the end of the day. I had the earlier battery version that did not register on the camera's meter and I misplaced the charger so I bought the new one with the new batteries. They work great and it is nice that the camera reads these new batteries. I honestly have not used them very much but it is nice to not be caught with a dead battery. The canon version is expensive-because they can- and you still would only have to recharge one battery at a time.

These batteries worked fine with my canon t7i. The battery life is quite a bit shorter than the canon battery that came with my camera. I also didn't get a lot of warning when the battery was dying. The battery indicator works on my camera but when it says it's almost dead it really means it. By contrast, I get quite a bit of life out of my canon battery after the red warning light first pops up.

I waited to write this review until I used both batteries in this pack through a recharge cycle. Both batteries held up very well in use (my unmeasured evaluation is longer than the Canon battery that came with my camera). I'm confident that on any reasonable day, that one of these batteries would last the entire day (but I do carry 2 with me, just in case). I've even used them on multiple day shoots and they did great. The only change I would make is that I would have a charging connection to an AC outlet. That's not a biggie for me and frankly, my simple cell phone charger (either in a car or plug-in) worked fine for me. A great product, especially for the money.

I've used these batteries with a Canon T6i for going on 3 years now. They last at least as long as Canon batteries, cost much, much less, and have been extremely reliable. They store well, fit perfectly, and endure tons of abuse. We shoot in the desert heat, temperatures as high as 115 degrees while we're shooting and sometimes for hours at a time - on the average, we take about 300 images per day, 3-4 days a week, and these batteries have held up exceptionally well. Can't recommend them highly enough!

I liked these batteries. They seemed to have solid battery life considering the size. But I just opened my camera case yesterday and one of the batteries had like a broken piece that expanded the battery size and it won't even fit in my camera anymore. So maybe not the best idea to get if you're wanting a battery to last you several years.

I have used this several times and although it doesn’t last as long as the original battery, it does the job. Considering the price difference, it is a really good value and comes in handy when you need it on a long day. Edit: Sept. 2022. Seems like you get what you pay for because battery life has dropped significantly and they are both swelling, making it a bad fit for the camera, not to mention dangerous.
