Assembly for changing lead battery with nickel cadmium battery charger

摘要

The lead battery assembly includes a voltage detecting circuit used to detect the voltage of a lead battery and an automatic voltage charging circuit. The circuits are connected to the lead battery and contained together with the lead battery in a housing. A connecting base is electrically engaged with the circuits, and the connecting base is adapted to engage with a cahrger for a nickel cadmium battery.The detecting circuit detects that the voltage of the lead battery reaches a certain value, and sends a signal to the voltage changing circuit to slowly lower the voltage. After the total voltage of the lead battery and the voltage changing circuit change from an increasing state to a decreasing state, the charger senses decreasing voltage and stops charging the lead battery so that the lead battery is permitted to be charged by a charger for a nickel cadmium battery.
