A power handle for electric toothbrushes is adapted to have a toothbrush head assembly placed thereon for delivery of driving power to the toothbrush head assembly. The power handle comprises a generally U-shaped battery compartment portion, a power delivery neck portion, and an end cap portion, and an electric motor installed within the power handle in a coupled power delivery relationship to the power delivery neck portion. The battery compartment portion has first and second legs arranged in parallel relationship one to the other. Typically, each leg is hollow, and has a length and a minimum inside dimension which is sufficient to receive a standard battery such as an AA battery. The power delivery neck portion, electric motor, and first leg of the battery compartment are aligned one with another; with an electric switch being mounted on them. The end cap portion spans across the ends of the first and second hollow legs so as to close them and so as to secure a battery in place inside at least one of the two legs.
