Chosen Solution
I am trying to change internal backup-batter of my Canon EOS Rebel T3i Digital SLR Camera. As of now I cant believe that there is no documentation or any information available on internet. I am looking forward to do this thing myself.
You cannot change the internal back-up battery of this camera, because it does not have one. The camera’s real-time clock and settings memory are powered by the same battery that powers the camera. A capacitor is used for backup so date/time and settings are retained for a while when the battery is removed from the camera. See the user manual, p. 34.
There is a battery, its accessible via a small barely visable panel inside the part the battery goes into, just below the the lid catch. Though I removed one out of my worki g camera to test in one that doesnt work and now my camera doesnt turn on. Still trying to find information about it and the batteries are like rocking horse poop, so be aware.
@ooikamheng see attached photo. Not easy to get to…hope this helps.
Perfect answer - thanks - we found out this the hard way. The door is fragile.
2020_1020_1103: rdcollins912 and Bob Bell Glad that both of you give a hope to my search. I looked through the place around and beneath the battery lid by using the tweezers and just ended up doubt :( Would you please show me in PICTURES where is it located and how to open the button cell slot?
I found it in my old 450D. I had to disasemble the front panel and detach the power board but it was tright underneath. I’ll order a replacement part see if it solves the problems I have…

And it comes with an working time/Date memory. no more time/date reset problem caused of built-in button cell :) Useless when it comes to needed, then i have to open the cast and customize it:)
