What size of batteries does it use and what is the expected battery life?

The HP 35s uses 2 CR2032 Li batteries. I still am using the original batteries that came with the calculator.

he HP 35s calculator takes two 3-volt CR2032 lithium coin batteries. Expected life depends on usage. I use almost everyday at job, and my previous calc lasted 5+ years.

I haven't done a test (like running movies for hours to clock the battery life), but I would say about 6-7 hours of use. I use it a lot, but only need to charge the battery every 2 days or so. No battery gets used when it's off, either (I know that sounds silly) - for example, I had charged it fully and the. Had it in my bag for 3 days before taking it out to use it, an the battery was still charged to 100%. So far, great battery life. Hope that helps.

this unit takes 6 AAA batteries. battery life is, obviously dependent on usage. my father uses it for about a half hour to 45 minutes, once per week and it has lasted a couple of months, but light output has dimmed. it is ok as a supplemental light but I wouldn't use it as a primary source

This was a gift to a grandchild in another state and I have no idea what size batteries it takes. Sorry.

Battery charge lasts about 5 to 6 hours. I bought 2 of them and just change to the spare it I am watching that long!I don't worry about the battery life for the price :)

Don't know, but battery life seems pretty long...I've used several times without need to recharge. Sorry I can't be more specific.

The small battery that comes with it lasts a couple of hours. I only use it with the larger battery. I have several of them. Two of the larger batteries always get me through a heavy day of shooting.

If you laid the unit on its back it's size is about like a stack of 12 magazines. I've never had battery problems either. It works at least a couple hours without plugging in. If I use it more than that, I generally have power available anyway and leave it plugged in, so I have not tested exactly the battery capacity. Overall a great unit for casual use in large rooms or small auditoriums. I love it and am glad I got it. We use it 4 or 5 times a year, have had it for a couple years, friends borrow it at times as well. Way better than a bullhorn, but not a high end DJ system either.

It uses 6 AA batteries, (it does not use C batteries). Apparently lasts up to 8 hours on one set. I've had a good experience with it so far.

It had batteries already in it and I don't remember what size, probably AA maybe two or three. I didn't pay much attention as it was a functioning toy upon receipt. Check in the info following the screen on toy and it should say. Have a good one!!!

If the battery is fully charged, it should last for about 6 hours. This is a rough guess based on my using it for about a week, a short time each day, before needing to recharge the battery.

It has roughly the capacity of a laptop battery. I don't know your exact laptop model, but I would expect that it would last about as long as with its built-in battery.

Battery life is good; the person who told me about. It, used it non stop for several days and since then infrequently but has not had to change batteries. I gave one to someone the day before yesterday and they used it 2 nights in a row non stop!

I have never timed it, but with constant use I'd say it lasts about an hour fully charged. It's really not a long lasting battery which I have to say has to be the only problem with it. It's a great tool but using it avidly for all kinds of projects, I could use a longer battery life. Your measure of a "good length" all depends on what you plan on using it for.

not very long, but it is OK. What I do is to buy some additional battery for it; I have 4 battery, I think it is too many. 2 battery will be good enough.

A large button battery-don't know size. Two supplied with the unit. Unit automatically turns itself off so I am still on original battery No clue how long it will last.

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.
