MSJ series

MSJ-400

General Design for Standby Power Applications

【Design Life】

Up to 20 Years in Standby Service at 25°C. Eurobat (20°C): >12 YEARS VERY LONG LIFE

【Operating Temperature Range】

Nominal Operating Temperature: 25°C (77°F)

Discharge: -15°C to 50°C (5°F to 122°F) Charge: -15°C to 40°C (5°F to 104°F) Storage: -15°C to 40°C (5°F to 104°F)

【Float Charging Voltage】

2.21 to 2.25 VDC/Unit at 25°C (77°F)

【Equalization Charging Voltage】

2.35 VDC/Unit at 25°C (77°F)

【Self Discharge】
