What kind of batteries does this need and do them come in the re-chargeable kind?

This calculator uses a type CR2032 lithium battery. It comes already installed. I believe that this is a fairly common battery, so replacing shouldn't be an issue. Also remember that it has a solar cell. Mine seems to run fine from the lamp on my desk. I also have a solar powered keyboard on my PC and a solar powered watch (Citizen Eco-drive) and they have been running forever. I haven't had the calculator long enough to know how long the battery will last, but I'm not worried.

The calculator uses type CR2032 which are not rechargeable but you can buy 5 batteries of that type for around $2.50. If you work in a reasonably well-lit place, though, you may never need a replacement battery as this calculator is dual-powered by solar energy first. I've been using mine daily for about 6 months without any problem at all.

It takes a round flat battery#CR2032x1 I don't believe they come in rechargeable.

it will take reg batteries but they are eaten up fast I use Duracell CR-V3, they work the best. I haven't used any rechargables

Item comes with one CR123A battery which is not rechargeable. I use surefire batteries and they are roughly $23/dozen.

I bought a charger from best buy with rechargable batteries. Or you can use a wall charger that you purchase separately

Probably a standard NIMH recharger. You can buy them for $5 and up -- I have a $40 one. The more expensive ones make your batteries last longer.

They came with their own charger and rechargeable batteries..But you can use regular batteries if you don't want the charger.

No batteries are included. I use rechargeable CR123s from lighthound with the charger they sell there as well. Awesome setup.

They are rechargeable batteries, like in a cell phone. It comes with a cord you plug in to charge it. Depending on usage, it'll last a couple days on a charge if used lightly. I use mine as an e-reader so it stays plugged in next to my bed most of the time.

Not rechargeable but you can replace the batteries. I think they are C batteries.

I have not tried re-chargeable batteries. I found a cord to plug in 6 volt and use it that way.

It doesn't take batteries. This IS the rechargeable battery. That said, it's a piece of junk. Mine never charged at all, and I returned it. There are much better options out there.

If you mean by re-chargeable battery, then yes! But if you mean pull-out battery, then no. Hope this helps. p.s. by the way, mine came with a battery as well as being a plug in unit into a 110 volt electricity power outlet.

Hello there! This battery requires 4 AAA batteries, and no they are not rechargeable.

It comes with its own rechargeable battery. Just make sure you install it properly to charge first use, and let it run right down before charging it again.

Uses AA batteries. You can buy the rechargeable ones, and use. Just get them recharged after each use.

No it isn't charged already, and I'm sorry but I doubt you'll ever be able to buy one that is charged at all. No batteries for devices like these come with a charged battery.
