What size battery does the unit use. Is It built in or does the battery have to be inserted?

This has a built in Li-Ion Battery. It can run for a very long time. Much longer than the phone or I-pad you will use to view it.

The battery is built-in. It lasts an insanely long amount of time. I fly with it weekly for several hours per flight. I only need to charge it once a week or every other week. Charges via USB cable.

The battery comes with the Bad Elf already installed. It's a rechargeable Lithium Ion battery. It connects to your devices with Bluetooth. It is a great little GPS and worth the money.

The battery is built in and the GPS comes with a USB charging cable. We use it connected by Bluetooth to an iPad and it barely drains down in a 6-7 hour day of driving. You won't need to replace this battery for a long time based on my experience. I'd guess 25-30 hours between full and low charge.

This unit has a built in battery pack that you charge up. The charge lasts about 4.5 hours.

Yes. Yes the battery comes installed within the unit. It had an initial charge to it from the factory, but you still should fully charge it before first use. It will hold a charge better and longer if the directions are followed. Mine seems to have a bit longer than advertised battery life. I'm OK with that. :)

I believe you have to plug it in. I don't see any place where batteries can be put in. I always plug it in.

This unit is powered from the voltage of the wire. No battery. There was is another model number that bruns from battery. I install those models. Just search it.

The unit is battery operated. The one I received did not include a battery.

My unit uses one AAA battery, which lasts weeks. A disposable battery works perfectly, but you might try one that recharges in a separate unit.

Built in battery. (I don't know exactly what type of battery it is. I just guess Li-ion rechargeable.)

No, it requires a special 12 volt battery which costs about $4.00. A battery is included with the unit though

The battery is built in, so you don't replace it. It has a USB connector, not unlike your cell phone, which you charge it either via your laptop or with the cord and plug that comes with the unit.

I believe it is C size battery. I own the unit but I am using the AC not battery.

It has to be plugged in to the access. power outlet. It has no built in rechargeable batteries.

The battery is built in. I haven't had to replace mine, but the specs do state it is possible to replace when it stops holding a charge.

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

Plug it in after use and that recharges the built in battery (or batteries). I have used this probably six months thus far on small messes and battery is still doing well. Not even certain that you have to "change them out" at any time.

AA batteries are used. I keep the main unit plugged in via the power adapted that came with it, but if you're looking for portability of the base unit then use the AA batteries.
