Storage Performance

Item		test method	require
Stock in normal temperature	1	Standard charging, the battery is stored for 30 days in an environment of 25±2℃, and the 0.2CmA discharge capacity (holding capacity) is tested	≥97%
Stock in normal temperature	2	After the above discharge, standard charge, 0.2CmA constant current discharge cycle 3 times, test the recovery capacity (maximum discharge capacity in 3 cycles)	≥97%
Stock in high temperature	1	Standard charging, the battery is stored in an environment of 60±2℃ for 7 days, and the 0.2CmA discharge capacity (holding capacity) is tested.	≥60%
Stock in high temperature	2	After the above discharge, standard charge, 0.2CmA constant current discharge cycle 3 times, test the recovery capacity (maximum discharge capacity in 3 cycles)
