These INSTEN Compatible Decoded Li-Ion LP-E6 batteries work as well as the original Canon battery. Since they are supposedly compatible with the original Canon battery, I charge them with the original Canon Charger. An after successfully charging them, I see they provide battery info when viewing the Battery Info menu on the EOS 7D Mark II. Consequently, just like with a Canon battery, you know the battery status throughout it's charge cycle. In my 7D MKII, they last more than an hour under average shooting conditions. However, after 1-hour, it is my custom to replace them with another fully-charged battery. When using the 7D MKII battery grip, I get 2-hours of shooting. I purchased two of these batteries, just for use in my battery grip. You cannot beat Overstock's price on this Compatible Decoded Li-Ion battery.
