Is this an internal battery?

you take off the back cover and put it into the space where the battery goes, then put the back cover on. They send you a new back cover which is larger than the original cover because this battery is larger. When the battery explodes, it pushes off the back cover but did not damage the phone. (Well, it might have done some damage, but I don't use that phone any more.)

Yes it fits just like the original battery only its taller.The cover makes it a good fit.

Yes. It's labeled 'extended' battery and is slightly larger than the one supplied with the phone, but is not as large as the Seido extended battery I'd gotten when I first bought the phone. I'd say it's okay to have for a spare, but don't depend on it.

Yes this battery I purchased was slightly shorter than the original one I had to put a piece of cardboard on the top to even make it work with my phone. Other than that problem it works great, my phone will last all day now without charging, but wish I would have known that I would have looked for something different.

It's a AA battery. So no, unless you have your own rechargeable AA battery.

It has an internal battery, but it is not servicable. The battery is listed to be good for five years.

Yes - mine came with the cord which is detachable from the unit, so you can use the internal battery for short trips.

No.. it's a non standard battery. See the answers under the replacement battery unit for clarification. http://www.amazon.com/this-battery-pack-made-batteries/forum/Fx1CB79G4V5RIC2/Tx1II6REXTAH6PK/1/ref=cm_cd_naredir?_encoding=UTF8&asin;=B00002N9ES&cdItems;=25&store;=generic

No! This is a good battery right now for holding charge. Was good price. Only it is not same size of old battery. Had to put filler around it to keep it tight in compartment but works good now.

Yes, their is an internal battery (not replaceable) that you charge using a standard micro usb cable and any standard usb power source, just like most other devices these days.

I have never opened up the inside to see the actual battery. The calculator comes with a plug that you plug into the wall and the calculator. This recharges the calculator so yes, the calculator has an internal rechargeable battery. Hopefully this answers your question.

Yes it is. It has a bulk charge and a float charge that gives the battery the charge it needs.

no,..it uses an internal lithium ion battery. But you can buy parts and replace it if needed,..but doubtful that you would ever need to replace it, as they last a LONG time.

It has an internal battery. No need to add your own. Lasts for at least 10 hours between charges.

There is no internal battery. It's basically a portable power strip / surge protector so it will only work if it's plugged in.
