The battery uses CC/CV charging with a charge limit voltage of 25.2 V, a standard charging current of 1.24 A, and a maximum charging current of up to 3.1 A, balancing stable charging with fast recharge capability. The standard discharge current is 3.1 A, while the maximum discharge current reaches 10 A, meeting the higher power demands during vacuum cleaner startup, high-suction operation, and power-level switching.
