Canon 70D no life, only blinks low battery on top LCD screen with dead

mine did this, I thought I would be in for a costly repair, I realized it was because i stored it with a battery and then it drained in the camera, even my other fully charged batteries would’t turn it back on. i took out the battery, feeling bad, didnt use it for about two months… then on a whim, I put a fully charged battery in it and it started up. moral of the story, dont let the batt discharge in the camera because it would cause errors, but by letting the residual current in the camera fully discharge over the time I didnt use it maybe reset something and it works like new again. I dont store it with a battery in it, anymore, I always remove batteries from my cam when putting it away.

My Canon 70D has suddenly started giving this trouble. Yes, I didn’t use it for a while (about a month or so) and it remained on the shelf with battery-in. Now, as I tried to use it, it suddenly blacks out at times when I select various options like reviewing the shot taken or changing the ISO setting etc. When it blacks out, it doesn’t respond to any function, only the battery symbol on top panel blinks showing discharged status (though actually it’s not fully discharged).

Now, I’ve taken the battery out and left it on the shelf to watch what happens few days later when I try to use it again with a fully recharged battery!
