This was a weird issue I experienced with my Texas Instruments BA II Plus calculator that was resetting the calculator when trying to compute the interest rate of a TVM calculation.
It seems that a low battery was at fault, and on inspection was showing a voltage of 2.8V instead of above 3V. I thought it was worth posting since I couldn’t find any solutions online, and this is the first time I have heard of a low battery impeding a calculation.

Did you solve the problem? I got the same problem here.
Replace the internal battery.
Love you bother. I was having the same problem. Whenever I pressed compute for NPV after putting in CFs more than 3, it used to get reset. I replaced the battery and the problem solved. I was about to buy a new calculator. But you saved my lots of money.
Again thankyou soooo much!!!!!
Do not use the AOS. That’s the reason why your calculator is returning RST 0.00
Thanks for the info! You really saved me a lot of stress, time and money. I had the same “warning” problem when I tried to use the CF function and it reset all the time.
Really appreciated!
thank you! had the same issue. Appreciate the post
Wow this really helped, my financial calculator kept showing RST 0.00 after I kept trying to find the interest rate. But after changing the battery it worked. Thank you!
This is awesome, thank you so much. I am sure this post has saved people a lot of grief and money.
Thank you so much. I literally thought that I had to buy a new one cause rest of the features were working fine.
Huge Thank you! Taking the CFP Exam in two days and I was getting the “RST 0.00” and then the calculator would reset when solving for I/Y.
It happened during my crash course review as well but then the calculator has been working since. I was about to run to the store to buy a “Back Up” calculator just in case. Glad you created this post. Super helpful for us Texas Instruments BA II Plus calculator users out there.
Cheers!
thank you so much
This was extremely helpful, thank you so much!
Where can we get a replacement battery for the ba2plus calculator? I am facing the same issue.
GREAT HELP, SAVED ME MONEY AND TIME!
Thanks a lot, confront the same issue, and solve it by replace the battery.
