An innovative electric conversion kit for two battery AA clocks or devices. The conversion is achieved by an external AC to DC power supply simultaneously powering and trickle charging the internal NiMH batteries. In the case of a power loss, the converter will act as a power back up and immediately switch to the NiMH batteries. Once power is restored, the clock automatically switches back to electric and then re-charges the NiMH for the next outage. The fully charged NiMH batteries can last for up to 3 weeks.
