1. Using oxygen recombination technology: maintenance-free 2. PbCaSn alloy for plate grids: less gassing, less self-discharging 3. High quality AGM separator: extend cycle life and prevent micro short circuit 4. ABS material: increase the strength of battery container 5. High purity raw material: ensure low self discharge rate 6. Silver-coated copper terminals (T1, T2 terminal), brass insert terminals and lead terminals improve the electric conductivity Typical Applications 1. All purpose 2. Uninterruptable Power Supply (UPS) 3. Electric Power System (EPS) 4. Emergency light 5. Emergency backup power supply 6. Auto control system 7. Aircraft signal 8. Alarm and security system 9. Electronic apparatus and equipment 10. DC power supply 11. Communication power supply
