Texas Instruments Rechargeable Battery for TI-84 C Silver Edition Graphing Calculator + Guerrilla USB Cable (Calculator not Included)

This battery works just like it came out of the box. I was a little concerned about buying the battery from here, but when I got it, it worked fine. You don’t even need to charge it as much because the battery lasts so long, weeks even. It was very simple to install, just make sure to put it in the correct way.

12 year old calculator still going strong with this new battery. Very easy to replace.

Arrived on time. Appears to be a direct replacement. Brought calculator back to life. Nice job TI. Price wasn’t bad. Worth it for the college student to keep the calculator going strong. Study hard kids, get a good job, make a lot of money - people are depending on you working hard, so they don’t have to. (Just a little joke there.)

I’m so glad I found this battery and charger on here. This old calculator belonged to one of my sisters, so easily almost 10 years old. The old battery was a dud after all this time. My oldest is now headed off to high school so I figured she could use this calculator and really wanted to get it working again vs having to buy a whole new one.

battery works great but the cord that came with it doesn't charge the calculator... fast shipping

So far, I like this product. I have had my calculator for 4.5 years, and the battery needed replacing. It works like new, and it’s a lot cheaper than replacing the calculator. It got here on time, and so my calculator will be ready to use when classes start back next week.

I was scared I was going to have to buy a whole new calculator. I wanted to try replacing the batter first and that worked. This battery came quickly, perfect condition, and they provided a chArger for the calculator As well. I’m super happy with this purchase!

My TI-84 had gotten a lot of use daily for many years. Of late, it did not hold a charge very well. I was going to buy a new $169 TI-84, when it occurred to me that I might just need a new battery. I was not able to change it myself, but a teenager had no trouble fixing it for me. The calculator is as good as new.
