  • Application: SLA replacement battery power station, power storage, intelligent manufacturing, solar street lighting, electric tools, electric vehicle, e-bike, medical apparatus and instruments

1.Overcharge:Normal batteries are charged at 1C constant current until the charging termination voltage is 1.5 times or after charging time reaches 1h, then stop charging and the appearance changes of the batteries are observed for 1h.
2.Over Discharge:After normal charge, test the batteries’ initial state. When the batteries are normal, discharge to 0V at 0.5C. Observe cell’s variation of appearance.
3.External Short-circuit:After standard charging of normal batteries, direct short circuit positive and negative poles for 10 minutes, external line resistance should be less than 5 mΩ. When the temperature of batteries drops to 10 ℃, the test is completed and the appearance changes of batteries are observed for 1 hour.
4.Thermal Abuse:The initial state of the normal battery was measured. After standard charging, the battery was placed in the oven. The temperature was increased to 130±2℃ at a rate of (5±2℃)/min and kept for 30 minutes. Then the appearance of the battery was observed for one hour.
