BATTERY PACK, POWER TOOL AND BATTERY PACK CHARGER SYSTEM
When providing alternating current (AC) power to operate AC powered devices such as power tools (such as drills, table saws, miter saws), equipment (such as lawn mowers), and consumer products (such as refrigerators, television, lights) without being tied to a fixed utility power supply typically requires a generator (such as an internal combustion engine based generator) or a battery powered inverter. In order to meet power and runtime needs for these devices, a battery powered inverter must be relatively large and expensive. This simple fact prohibits their use in many environments.
