This is a high-performance 12V sealed lead-acid battery with an 80Ah capacity rating, specifically engineered for demanding backup power and stationary applications. The battery delivers its full 80Ah capacity when discharged over a 10-hour period at 25°C with a 10.8V cutoff voltage, while maintaining substantial capacity at faster discharge rates of 70Ah (5-hour rate) and 49.6Ah (1-hour rate). Its compact yet robust design measures 260mm in length, 168mm in width, and 209mm in height, with a total terminal height of 209-210mm, making it suitable for space-constrained installations while weighing approximately 24kg (52.91lbs). The battery features professional-grade T5/T9 copper terminals that ensure reliable electrical connections and minimize voltage drop during high-current applications. With an exceptionally low internal resistance of approximately 4mΩ when fully charged, it can deliver impressive peak performance with a maximum discharge current of 800A for 5 seconds, making it ideal for applications requiring high instantaneous power delivery.
Temperature performance is a key strength of this battery, operating effectively across a wide range from -20°C to +50°C for storage, with optimal performance achieved between 22°C and 28°C. The capacity is temperature-compensated, maintaining 100% capacity at 25°C, 85% at 0°C, and 65% at -15°C. The charging system supports both float and cyclic charging modes with temperature compensation features – float charging at 13.50-13.80V with -18mV/°C compensation, and cyclic charging at 14.50-14.90V with -30mV/°C compensation, with a maximum charging current of 24A.
One of the battery's standout features is its excellent self-discharge characteristics, retaining 91% of its capacity after 3 months, 82% after 6 months, and 65% after 12 months of storage at 25°C. This makes it exceptionally reliable for standby applications where the battery may remain unused for extended periods. Designed for longevity, this battery offers a 10-15 year floating life expectancy at 20°C, making it a cost-effective solution for critical backup power systems, UPS applications, emergency lighting, telecommunications equipment, and other mission-critical installations where reliability and long service life are paramount.
