Direct replacement

Perfect battery replacement for my son's calculator. It works great and was a great price.

My son’s old calculator was given a new life for his sister just by getting a new battery. We saved $110 by doing so.

Wont charge. When using the calculator, I have to keep it hooked to the charger, which was an inprovement over my last battery, but i recommend buying a different one.

TI 84 calculators seem to be a favorite of our schools, despite the fact they’re known to have unreliable batteries. We recently had to replace the batteries in two of our calculators so we decided to give this replacement a try. It fit perfectly, and the calculator fired right up, so it was perfect in that regard. I wish it had come with the little screwdriver needed to remove the back cover, but I knew that didn’t when I ordered it, so I ought not to complain about it. Aside from that, it worked perfectly in the calculator and was exactly what we needed.

Battery fits and calculator functions, however the calculator will not charge with the battery.
