Find the two notches at the top of the calculator. Insert a flat-head screwdriver into one of the notches and carefully pry open the top end of the case. Locate where the case is still attached at the sides.

The batteries are located at the top. Slide the flat-head screwdriver underneath each battery and they will easily pop out.

Positive side of both batteries should face 'UP'/away from the circuit board

Thanks for the guide! :) Worked! (Although they didn't engineer the case to come apart easily...)

I'm so glad I looked this up. VERY helpful. A simple Google search indicated that it took a 3 volt, flat 'coin' style battery. These batteries, however - I actually have in my desk at work in a 3 pack. No need to even take a trip to the store now. Oh, BTW - the 3 pack was purchased from Walgreens. They sell them in a 3 pack for around $10.

I changed the batteries and instructions on circuit board says to "please short the reset pad after changing the batteries ". How do I do that?

With the display facing down then you will see that in the center of the circuit board are two small raised posts about half an inch apart - they look like part of the circuit. With the power on touch a screwdriver or nail across both posts at the same time. Without doing this step none of the buttons will do anything after replacing the batteries. The pictures on this page don't look like the insides of my calculator though, and I cannot see these posts here.

I've had two of these calculators for many years. I finally went to replace the batteries and one of them seems to be sealed shut, it can't be opened without destroying the case. The second one opened ok. I was in Walmart and they have these in the school supplies section. A new TI-30Xa was only $9. The display is a bit larger as well. If you can't open it then this is a low cost alternative. BTW, In the one that I changed batteries, it work without any reset. but this may vary.

I don’t know what size the Phillips head screw driver is that fits but it’s smaller than a #1. $5 down the drain. Use a sharply pointed pen knife.

I dont see any raised posts to short out on my circuit board, where are they? My circuit board says to do that yet doesnt show you which posts to short out. My batteries are replaced but as you say, the buttons are now doing nothing.
