ABSTRACT:
A plastic battery housing has a recessed compartment with a contoured support surface which supports two AA, AAA, or AAAA batteries in the same charging position as a single C or D battery. The support surface has two concave depressions suited to support AA batteries, one on either side of a larger diameter depression suited to support either a C or a D battery. A first contact is positioned to engage the positive terminal of the C or D battery, and a second contact is positioned to engage the positive terminals of the two AA batteries. Narrow diameter concave surfaces may be formed within the AA support surfaces for alternatively supporting AAA batteries which would also engage the second contact. A sliding contact element alternatively engages the negative terminal of a single C or D battery or the two negative terminals of AA or AAA batteries.
