I bought these for a power grip and extra power available for my 3Ti. When they arrived I charged them up and installed them in the grip and they worked just fine. I took the grip off and just used the single battery and the camera worked fine. They are a great savings and value.
I have a large yard front and rear, was looking for a battery for my cordless electric lawn mower that would give me more time and steady power to complete my mowing. This battery really met my need.
