Description
Voltan 12V 8.2AH UPS Battery
The Voltan 12V 8.2AH UPS Battery is a premium sealed lead-acid battery engineered to deliver consistent backup power for UPS systems, security devices, telecommunication equipment, and emergency lighting. Designed with a nominal voltage of 12V and a nominal capacity of 8.2 ampere-hours (AH), it ensures dependable energy storage and discharge performance. Its high-conductivity T1 copper terminals reduce resistance and increase overall electrical efficiency, while the battery’s internal resistance of approximately 28 milliohms (mΩ)—when fully charged at 25°C—contributes to stable power output under demanding conditions. The Voltan 12V 8.2AH UPS Battery features advanced charge cycle management, supporting a maximum charging current of 2.1A and maintaining ideal performance through a float charging voltage range of 13.60V to 13.80V, with intelligent temperature compensation at -18mV/°C to prevent overcharging or thermal degradation. This battery adapts to different discharge rates, offering 8.2Ah at 20HR (10.5V cut-off), 6.6Ah at 10HR, and 4.58Ah at 1HR (9.6V), making it suitable for both long-duration and high-drain usage. It can handle a maximum discharge current of 105A for 5 seconds, making it ideal for devices with high inrush current needs. The Voltan 12V 8.2AH UPS Battery also demonstrates excellent self-discharge performance, retaining 91% capacity after 3 months, 82% after 6 months, and 65% after 12 months of storage at 25°C, thereby minimizing maintenance and replacement frequency. Built to withstand diverse environmental conditions, its operating temperature ranges from -15°C to 50°C during discharge, -10°C to 50°C during charging, and -20°C to 50°C during storage, ensuring consistent functionality in extreme climates. Physically compact yet powerful, the battery measures 152mm in length, 67mm in width, 99mm in height, and 105mm total height, with a lightweight design of 2.10kg (±5%), making it easy to install in confined UPS compartments or portable power devices. Whether for home, commercial, or industrial backup power needs, the Voltan 12V 8.2AH UPS Battery stands out with its reliable capacity, low maintenance, thermal resilience, and long cycle life—making it a trusted solution for critical power continuity.
