This is a 3xAA size battery holder, 3 AA cells in series. It has a snap lid with screw for additional security (as in, security against accidentally opening) and a switch.
Unlike most all the other sellers, I actually include a screw, I don't know why others don't !
3 Alkaline AA cells in series will give you from 4.5v full down to about 2.4v empty.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
