Duracel 76a is a standard alkaline battery according to this

But No, LR44 is the same as 76a. Did you change both?? You said 'I replaced THE battery', there is clearly two batteries.

I carefully and slowly pried mine open with a flat head screw driver, starting at the side of the top end.

1. Using a small phillips head screwdriver, remove the six small screws off the back. Be careful not to lose the small screws.
2. Using a small straight head screwdriver, insert it into one of the two slots at the top of the calculator and twist. The top of the calculator should pop open.
3. Remove the back of the calculator.
4. Using the straight screwdriver, insert it below the bottom of the two silver batteries and pop the batteries out.
5. Replace the batteries with two new GPA76 batteries.
6. Replace the cover and isert the screws.
