Works great in an older TI-84 calculator
Our son’s TI-84 has sat unused for a couple of years so the battery had totally died. This one is a solid fit, was mostly charged out of the box, charged up fully, and works great.

Only 8 month life
After 8 months, it became intermittent, causing the calculator to flash off and on and lose work. A new replacement battery restored the calculator to proper functioning.

It came charged
This battery came fully charged, which was a bit of a surprise. In my experience the unfamiliar brands of lithium ion batteries are very risky to buy. Many times they come fully discharged, and it damages this type of battery when they are kept fully discharged for prolonged time. Often they do not charge at all and I end up having to return and try a different brand. This one looks a bit cheaper than the original but it fits perfect and works perfectly. It has the same part number as the original that came in my calculator, but as the description indicates, it is higher mAh so it will last longer between charges.

Don’t buy
It turned on once when installed then the next time I tried to use it. It didn’t want to turn on even with a power source.

Quick fix
We have only had the battery for a week, but it fit my daughters ti-84 plus CE python calculator and great value versus buying a new calculator. Installing was super as my teenager installed it.
