Abstract
The battery charge indicator provides a color-coded battery status indicator system adapted for attachment to or adjacent the battery compartment on a power tool body. The system includes a first member that is adapted for attachment to the surface of the power tool. The front face of the first member is provided with hook and loop fastener material thereon. A second member has a first face fabricated from green-colored hook and loop fastener material and an opposite, second face fabricated from red-colored hook or loop fastener material. Display of the red-colored face indicates that the battery needs recharging. Display of the green-colored face indicates that the battery is charged.
