Abstract:
1. A battery receptacle system, comprising: a first dual-contact assembly including a first negative contact adjacent to and electrically isolated from a first positive contact, the first negative contact and the first positive contact being configured such that when a first battery is in a first orientation in the battery receptacle system, the first positive contact electrically connects with a first positive terminal of the first battery without the first positive terminal of the first battery electrically connecting with the first negative contact, the first dual-contact assembly including a first radial notch for positioning the first positive terminal of the first battery to electrically connect with the first positive contact at a first position; and when the first battery is in a second orientation in the battery receptacle system different from the first orientation, the first negative contact electrically connects with a first negative terminal of the first battery without the first negative terminal of the first battery electrically connecting with the first positive contact; and when a second battery of a different standard size than the first battery is in the first orientation in the battery receptacle system, the first positive contact electrically connects with a second positive terminal of the second battery without the second positive terminal of the second battery electrically connecting with the first negative contact, the first dual-contact assembly including a second radial notch for positioning the second positive terminal of the second battery to electrically connect with the first positive contact at a second position different from the first position; and when the second battery is in the second orientation in the battery receptacle system, the first negative contact electrically connects with a second negative terminal of the second battery without the second negative terminal of the second battery electrically connecting with the first positive contact, the first dual-contact assembly positioned on an opposite end of a battery relative to a second dual-contact assembly when the battery is installed in the battery receptacle system.
