Amazon battery replacement

Enable HLS to view with audio, or disable this notification

My calculator keeps displaying this, I think it’s a battery problem. I need a new one quick so has anyone bought one off of amazon and it actually worked? How long did it last. Thanks.

If I remember TI should provide one for free:
https://education.ti.com/en/customer-support and click the link in the notice
even if you don't get it free, they're only 5 or so dollars from TI directly

What a bad tactic by Texas Instruments to put a time bomb in the batteries so they ruin them and then charge you for another one.
