Rebel t3 has fully Charged battery, but won't turn on....any suggestions?

[Chatty94]

I have tried two fully charged batteries, but my rebel t3 won't turn on.....it is about 4 years old....it has not been dropped or damaged....and I used it about 3-4 weeks ago with no problem. Any suggestions?

I did read in the manual that there are two different batteries......I have no idea where the second one is located or even how big it is.....

I had to buy a new battery that was NOT the Made in China crap battery.

I take excellent care of mine too, and only used quality batteries... I ended up buying a new camera...

Ugh, I don't want to have to do that. My batteries and charger are both from Canon too.

If it turns out that camera is defective and you need to purchase a new one look into the refurbished cameras at the Canon eStore.

Good prices, same warranty as a new camera, and the Canon Loyalty Program will give you a discount.

My rebel t3i wouldnt turn on! Thougt it was the battery so I bought a new one. Didn't work. Read some post and thought maybe there was a loose connetcion where the battery goes or the memory card. If either one of those isn't secure it won't work. Not the case. It was my memory card, I has switched it from my Nikon to my Canon and it wouldn't work. I put the memory card into my Mac, deleted everything off of it, put the card back in and the camera works fine. Years of using cameras and I guess I am an idiot....but you don't switch memory cards back and forth unless you format them first. MY BAD.

Happy to have finally solved this problem and at no cost..except now I have a back up battery..which isn't a bad thing.

Thank you, lauras2dolist, for your message. That must have been the issue with my Rebel, as I also changed memory cards and it worked just fine again. Thankfully it is working ok right now. Thanks again!

That's good info and thanks for sharing that data.

It's somewhat well known that you should not swap memory cards between cameras unless you format them, but it hadn't occurred to me that this could prevent the camera from turning on.

TCampbell that was amazing advice and IT WORKS!!!! My T3I stop functioning 2 days ago with all the symptoms describe by the other post. I was also ready to and buy a new camera, HOWEVER YOUR ADVICE ABOUT THE USING MEMORY CARD IN NIKON AND CANNON PRODUCT WORKED.

I had Nikon footage on a memory card that i used in my T3I first then Nikon then brought it back to my Rebel and of course it wouldnt function properly. I put a different card in and my cam came back to life.  It absolutley works. Thank you so much for your care and delligence in trying ot get to the root of the issue for quite sometime but sticking with it and posting for people like me who really love my cam. THANKS AGAIN AND KUDOS

My memory card wasn't even switched between different brands, only between two Canons, and seems to have caused the problem, even after trying a new card.  Trying different memory cards until this fix worked turned my very expensive brick into a working machine again.  I can't thank you enough.

I had a similar problem with my T3i, this morning.  Camera would not power up.  After reading your comments about checking the bay doors, I reseeded my SD card and battery and crossed my fingers.  

To my surprise, the camera came back to life.  It was really scarry, to think of replacing my baby and the money required to do so.
