Artman Hero 12 Battery 1800mAh (2-Pack) for GoPro Hero 12 11 10 9 Black and 3-Channel Quick Charger, Fully Compatible with GoPro Hero 12 11 10 9 Enduro Battery and Charger

The charger works well, red light is charging, green light full charge. I’ve been using an older phone charger rather than the recommended 2amp. I hear the 2amp charger cuts down charge time, especially with multiple batteries being charged. It has been taking me about 2-4 hours to charge several batteries at once. Once charged the 1800ma batteries do last longer. For me almost twice the record time at factory settings on my GoPro 11 black. The batteries fit with no problem and work just like the 1200ma batteries, just better. I haven’t had to use them in really cold weather so no detail there. Overall I bought extra sets of batteries to be out all day recording. A good buy.

I bought this to add to several batteries for a Go Pro 10 Black. This seller is absolutely amazing! When I let them know about a problem, they not only made up for the issue they went above and beyond what was expected. I could not be happier with this purchase and would buy from them again in a minute. I post very very few reviews and will tell you I am not paid for them. This business understands customer service!!!!

This comes in handy. Does a great charge

I initially chose this item because it was very competitively priced. A few reviews were critical of the battery quality -- not holding charge, undercharging, etc. All mentioned the customer service as very good. Initially, I received 2 batteries, one never got more than 18% charge, and the other would hit 100% but recording time was shorter than expected. This was after I put them through 5 charge / discharge cycles which you should do before passing judgment. The seller requests to be contacted before returning to Amazon. I used Amazon messaging and described the above. Then in reply was request for shipping address and 2 new batteries and charger were on the way Priority Mail. Outstanding way to treat a customer. I gather that there is some variability in quality of lithium batteries because I have seen this with tool batteries. The new batteries here appear to be working well and are consistent as I break them in.No worries ordering from these folks as they will stand behind their products.

These oem batteries last longer than some aftermarket blue tag batteries.

I thought it was just me not using it regularly, and the batteries slowly dying every time I wanted to use them, but I recently needed it to work regularly for a few days on a trip, and the batteries for pretty much immediately after being fully charged. They show 100% charge, but as soon as I start a video, they die in less than a minute. The original hero 10 battery still works great, so it's definitely these batteries.

UPDATED REVIEWseller reached out to me and sent me a brand new set completely free to replace the faulty one. New batteries and charger work flawlessly now. Hold charge as they should and I have sero problems. Used all of them on full cycles 4 times and they are definitely on par with originals1 original GoPro battery easily outlasts 4 of those... And more.I do have 2 GoPro batteries but needed a charger. Decides to try these since reviews were promising.Unfortunately the battery life is really really bad. They might be defective. I don't know.All I know is that I used both of them from 100% to 10% life twice and the performance is the same.I was recording a 10 minutes video on my GoPro hero 9 and the battery went from 100% to 62%. Same thing with the second one. it went from 100 to 67.So basically I am looking at 30 minutes of footage MAX per battery.As a comparison while using original GoPro battery I can record over 2 hours of footage before it dies. That is not right.Also if you charge the batteries in included case, and leave them there unplugged they will discharge. This makes zero sense as the charger is also sold as travel case.To summarize.You get 2 batteries that have 25% of performance comparing to original and you get a charging dock that will discharge your batteries while you travel.This is not a good deal

I purchased this for the charger since the GoPro hero 12 I purchased did not come with a charger The two batteries that came with the charger works well with my GoPro hero 12. They don't last as long, but they are a nice bonus. The chargers is nice to have so you charge 3 batteries at once. It's nice that this is small enough that it fits in a jacket pocket. Now I can charge batteries at home or while driving.
