Just to clarify, your calculator just dies due to a low battery even though the battery icon still shows full charge? I can't really tell from your question, have you tried using a new battery?

It sounds like the battery is on it’s last legs. The TI-84 series is the high school calculator, and as such many of them end up neglected and sold at a discount to anyone willing to deal with the issues they have since acquired. This is a particularly known issue on used ones. I would change the battery out and rule out that issue since it’s so cheap.

TI sells the battery and charger here. If you just need the battery, this is the battery you want. The part number is 3.7L1200SPA
