Canon dk100i battery change
it's very easy you have to unscreww on the back of the calculator the 2 small screws and then remove the top and be carefull not to unplug the small wires. Inside you will see the battery holder and you will need to remove the battery carefully by pushing from the side of it with something vry small (like a dime) and then replace it by a new battery type CR2016. Then you put back the cover and the screws.
After that you will have to do a reset with a small pin or with the tip of a pen.
Then it will work as a new one.
I just did it yesterday and itis working pretty well.
Good luck
