Cell Phone for emergencies or for people that want cheap basic phone

Runs on one AA battery.  If used for emergency only I would put a lithium AA battery in it, it will work with Lithium/Alkaline/NiMH, lithium batteries will hold their charge much better than other common batteries & are better in cold weather than Alkaline.
