Except for the flimsy tool/screwdriver which did not fit well to unscrew the back...the battery and charging kit work great.

Nice little kit for the calculator. The calculator started right up once we changed out the dead battery using the included keychain screwdriver. The new battery was 2/3 full, so the calculator is on the included charger overnight.

It fit my calculator so that I didn't have to buy a new one.

Bought a TI 84 and the battery was bad out of the box. Turned out this was a known issue. Reached out to TI for warranty support. After no response after a couple of days, I came here. This has worked beautifully. Placed the order, replaced the battery in the calculator, had it charged and my student go through his first test before TI finally responded. Not pleased I had to spend the money on a new calculator, but very happy this was available and has held up.

Brought a brand new TI calculator and battery was dead upon opening the box.I bought this based on reviews and it worked great. Proved that TI unethically sells expensive calculators with dead batteries and won't replace when asked.TI wanted me to return this one to Amazon after I already installed it, but no way would I do that.I would recommend this battery!

My daughter’s calculator died and this was the perfect replacement to get it working again without purchasing an entire new calculator. Would recommend.

I ordered this because my TI84 Plus CE’s battery fried out. I looked up solutions, and decided this would be cheaper than buying a new calculator.The screwdriver that comes in the package didn’t seem to fit with the calculator. Thankfully, I had other bits that did fit the screws and opened it that way. The new battery worked immediately; the charger that came with it also charges it like new.TLDR: Have a screwdriver bit, but the battery is amazing.
