The manual (available from education.ti.com) says the TI-83 Plus takes a CR1616 or a CR1620 battery.

Get the number off of the battery and do a Google search. Ebay or Amazon is usually the best.

That part number is for an APC Back-UPS ES USB 750VA which, per the APC website, uses the RBC4 replacement battery.

You should be able to see the item number on the current/old battery. I personally don't think this one will fit since the ports are different. You are probably looking for item # 00801-0638 or a similar number.
