  • RECHARGEABLE LEAD-ACID BATTERY COVER
    Publication number: 20110140651
    Abstract: A rechargeable lead-acid battery cover has a casing, two power outlet line through-holes, a circuit board and a charging assembly seat. The casing is provided with a holding space, and the power outlet line through-holes are set at one side of the holding space for penetration of anode and cathode leads, and also for electrical connection with the positive/negative contacts of the lead-acid battery. The circuit board is assembled into the casing's holding space, and connected to the positive and negative contacts through anode and cathode supply lines. A charging assembly seat is set on the circuit board and also electrically connected with anode and cathode supply lines, while the charging assembly seat is connected with a charging power source, and the lead-acid battery is charged through anode and cathode supply lines. The lead-acid battery can be protected and the charging function can be guaranteed.
