RECHARGEABLE BATTERY OUTPUT EXTENSION CIRCUIT AND METHOD OF USE

The battery output extension circuit has a switch to supply energy from a first rechargeable battery to charge a capacitor and a second rechargeable battery and then interrupt that supply of energy. The battery output extension circuit has another switch to subsequently enable energy to be discharged from the capacitor to power a load. The sequential charging of the capacitor and the second rechargeable battery, interruption of the charging, and subsequent discharging of the capacitor to power a load is repeatedly performed. A switching configuration can reverse the direction of charging such that the second rechargeable battery supplies the energy to perform a similar repeatedly performed sequential charging of the capacitor and the first rechargeable battery, interruption of the charging, and subsequent discharging of the capacitor to power the load.
