Review on Artman Enduro Battery 3-Pack For Gopro Hero 11 Black, Hero 10 Black, Hero 9 Black With 3-Channel USB Intelligent OLED Color Display Charger (Fully Compatible With Gopro Hero 11/10/9 Battery Charger) by Black Holstead

New update: I received a replacement from Artman and had a better experience. One of the three still let me down but two of them were on par with OEM batteries for record time and were "close enough” for cold power loss while storing. After a week I still had 88% of my capacity. One thing I did find interesting was the speed of recharging which was faster with the Artman vs OEM.I am not having the greatest experience with these batteries. After charging, I have them in my bag for a few days before use. I had 70% after 3 days, and 68% after 4 when finally put in my GoPro 9. The OEM had 97% charge after 4 days of storage off the charger. I plan to cycle these a couple of times and see how it goes from there. If there is a change I will update my rating.Update: they are getting worse. Cycled through my 3 Artman batteries and 2 OEM twice, then charged them all up using the Artman Charger. Confirmed they were at 100%, let them store for 7 days. OEM was at 97%, all 3 Artman were at 55%. I expect some loss over time, but this is unreasonable. Tried to reach out, but their website is offline. I am happy for the extended return period at least.
