TI-89 battery status?

<p>How long do your batteries usually last on this calculator? I’ve been using this one since the second half of last year (didn’t use it much over the summer, of course)</p>

<p>TI-Connect says my battery status is GOOD</p>

<p>Is there a FAIR and/or LOW status, below GOOD? </p>

<p>just wondering how much I have left, considering “GOOD”</p>

<p>thanks</p>

<p>if ur battery is good, than its good. if its said its low battery, then it still have like 5 hr of life left, at least for me anyways.</p>
