The present invention relates to a method for charging a sealed lead-acid battery that provides reliable and stable power to a load during a power outage.

なるという問題があつた。Conventional Structure and Problems Conventionally, sealed lead-acid batteries have been charged using trickle charging, in which each cell is continuously charged at a constant voltage of 2.2V to 2.35V. However, sealed lead-acid batteries use a negative electrode absorption type sealed system (hereinafter referred to as sealed lead-acid batteries) in which the negative electrode absorbs and removes oxygen gas generated from the positive electrode during charging.
In addition, since a non-fluidized electrolyte is used, the amount of liquid is smaller than that of conventional liquid lead-acid batteries, and some of the water in the electrolyte scatters during trickle charging, resulting in a decrease in the amount of electrolyte. There was a problem that the product deteriorated and reached the end of its life prematurely.

While the life mode of general lead-acid batteries is mainly due to corrosion of the positive electrode lattice made of a lead-antimony alloy and cell-to-cell variation in self-discharge due to antimony deposited on the positive electrode plate, sealed lead-acid batteries The deterioration life mode of storage batteries uses a lead-calcium alloy that has less self-discharge and lattice corrosion, so such factors are unlikely to cause the battery to reach the end of its life. The amount of liquid is relatively small, and the capacity decrease is mainly due to evaporation of water in the electrolyte or dissipation of gas.
