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.

Nice post! My batteries just gave up after 15 years. This whole time I tht it was a solor calc, LOL! Thanks for the easy instructions.

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?

Esther Reese - Antwort

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.

lasharlavenue - Antwort

On my circuit board I have a circular pad that looks like the PCB side of a membrane keypad labeled “reset”. I reset mine by bridging the contacts of this with the screwdriver. I did have the two raised contacts (smd jumpers, by the look of them) but wasn’t able to easily short them because they were buried in red epoxy.

I successfully replaced this in my calculator today. Thanks iFixit!

Notes:

The A-76 batteries interchange to a 357 watch batteries.

The new version of the calculator is $9 in the School Supply section at Wal-Mart. I didn’t realize it was so cheap, and paid almost this much for the two batteries. oops.

Elizabeth Greene - Antwort

I truly appreciate your help with letting me know what battery the calculator uses along with the very simple a precise instructions. Life is so much more rewarding with someone like you who is happy to help your fellow person!

I bought 15 LR44 for my cat’s Laser light. Then I wondered what battery my calculator uses. I’ve been wanting to change the batteries for a while now. So, I started wondering if the calculator would use these batteries too. How awesome that the batteries I purchased online from Walmart for $5.86 are the exact battery I need!

Traci Perronne - Antwort

Interesting but I can buy a new calculator for $8.

mikecurnutt - Antwort

Why not just buy a brand new TI-30Xa for the cost of its two batteries!
