How long does the battery last?

I seem to be charging mine twice per semester. I use it heavily. The battery on this thing is phenomenal!

Rich,It depends on the user. As a teacher I went over five months on the first charge, students will get a few months longer.

Sorry for the late reply, I got the calc for my son. He said that the battery lasts a long time. His is still full, and has been practicing quite a bit this summer.

It depends on the calculator. I'm a teacher, and mine lasts a long time between charges, perhaps a month or two, but a couple of my students' calculators do not seem to hold a charge very well at all. I've charged their calculators for them, and they still went dead a day later, so it's not just that the student forgot to charge it. The non-color TI-84s lasted almost a year on one set of alkaline batteries, and frankly I would prefer alkalines over the rechargeables.

depends on how much you use it, I replaced the batteries about a couple months

this unit recharges, although I haven't actually tested the amount of usuage per charge, I will say it appears to be quite adequate, it seems to last for a very ample amount of time, and I have no issues with it at all. Now if you mean how long does the actual battery itself last, well, I haven't had the unit very long, but I'm feel very positive that the actual battery will last for many many years. I really do highly recommend this unit.

Hi! As you said, it tends to consume the battery. About 8-10 hours. Sincerely,

In my experience, a fully charged battery lasts 7 to 8 hours, depending on how loud you have it and how far from the base station it is.

Hi,I have mine since two years ago, the battery had a duration between 2 and 3 hours, but since one year ago it last around 30-45 min.

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

Up to 4 hrs, but it takes awhile to drain the battery. Everyday use for a week and still running in a single charge.

I don't think it's more than a couple of hours, from a drained battery. But I'm not 100% sure. Definitely not an all day thing though.

battery life is good (Haven't done an exact measurement, but it seems like I recharge about every 3 or 4 days). It has an automatic sleep function that preserves the battery life. Full charge in about 2 hours.

Hi, I have not used it that long, but so far, the battery is holding up. Have not tested it on an all day run!Sorry I can't be of more help!

I only use mine about half the day, but the battery last as long as I need it to. HINT: I charge it every morning before starting to use it.

I really haven't tested the battery life per say.....but I have had it on for more than two hours with the battery still holding charge. Hope this helps.

I'm not sure about the battery life. But I haven't changed battery yet since I bought mine. Just be sure to turn it off after you use it.

Not long. 20-30 minutes max. Mine came with an extra battery, which makes it use able. You always have to have a spare charged. Other than battery life, it works great.

the battery works quite well. it lasts at least one to two days if you consistently use it. although its off for a while, you still can turn it on without losing power not being used.

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

Yes, About 3 hours if it's totally dead and about 2 and a half if you want to just charge it. The battery itself lasts for about 2-3 days for me without having to plug up on full.

at least 2 hours. maybe even 3. Its been a year now and I still have 2 hours remaining in my battery and I'm a student. So i've been using my laptop extensibly.
