I have a T3i. I took it out on a very hot day, snapped 4 pics and it just stopped.

They were new ones that I ordered for this trip. I bought them as a combo with a car charger. Pretty sure that they are faulty.

Lol! I believe that I learned that the hard way, or at least ordering online. One of my first two batteries that I bought at the same time that I bought the camera 3 1/2 years ago was not Canon and it is still going strong. But, I think from now on I will stick with Canon. Thanks for the input.

Thank you for the input. I'm still hoping that it was only the batteries. Haven't had the time to take it out since I got it working again. So, I don't know how it will do on an outing yet.
