Does this replace the existing battery or does it connect via usb for additional charge

Yes it is the equivalent of 3 batteries, it charges well with the 2.0 amp charger. It doubles the thickness of the phone. It is a great case compared to others.

No.It connects to the battery harness with the quick connect that you need to get.This is an excellence addition for usb power.

Not sure, there is a separate internal battery that I believe just adds extra charge like having double battery. I don't think it recharges your original battery. But however it works it works well, holding a charge throughout whole day.

Yeah, you can carry and extra battery and change it out...on the fly. What they mean is you charge one in the camera, take it out, put the extra battery in, charge it then take it out. You will have two charged batteries. But, you charged them in-camera. The USB cord can be used to plug into a wall socket or USB socket.

Yes. There is a slot right next to where the battery goes to stow the USB receiver. You just slide the bottom off like you're going to replace the battery and there's a little slot there for storage.

Between the 2 USB ports is a micro connector that plugs into the external battery with a USB connector on the other end . You just plug that into any USB port and charge the external battery. Easy !

It doesn't have the new charger connected but there's an extra USB out you can use your own cable

It has a battery built in that charges with the supplied USB. Not replaceable as far as I know.

Since this battery is also available thru Radio Shack, I assume the clerk at the counter can order it for you. I simply used the old connector on the new battery.

It is rechargeable by USB. Not sure about battery because I don't use it much so haven't looked for a battery to change.

After I installed the new battery, it already had a charge (I don't remember how much) but it was sufficient to work for a day or so. Then I just put the phone on a charger and it worked fine. I noted that I actually got LONGER battery life from the replacement than I ever had with the original - but that's because it has more mAmp hour storage. So if your battery does not charge up after install, I suspect there may be another issue with the way it was put in.

there is a battery inside the unit that doesn't need to be replace, it is rechargeable, to recharge it just connect it to a USB port and that is it.

Yes it will. Its an external battery which uses USB drive to connect. It also comes with laptop connectors for generic dell, hp, sony etc that can be used to connect using your existing laptop charger.

In the directions that came with my device, there is no reference to charging the battery, only to replacing it. In specific reference to the cable, the directions speak only of transferring data to a computer, not about charging the battery.

That's a good question, Joan, and I do not have an answer yet. The battery can probably charge through the USB connection and a phone charger. Since the battery itself has no indication of whether it is taking a charge or not, I will need to dig out my voltmeter from wherever I left it and test this.

Yes, it has a USB connection to charge the battery. The problem is that it doesn't maintain the charge long enough to charge other devices.

It replaces the existing batter and back cover. Over 3 times the original battery
