The evaluation was performed by a 3CA discharge cycle life test under an environment temperature of 45 ° C. In addition, it is known that when this evaluation is performed on a conventional lead-acid battery, the service life is extended due to corrosion of the grid of the positive electrode. In this cycle life test, a process in which the battery was discharged to 8.4 V at a constant current of 3 CA and then charged by two-stage constant current charging was defined as one cycle. The second-stage constant current charging is a method of charging to 14.4 V with the first-stage current (0.2 CA), and then charging for 4 hours with the second-stage charging current (0.05 CA).
