Product details
The HR series to which HR75-12 belongs is a high-power VRLA battery, offered in 6 V or 12 V monobloc forms, with per-battery power covering 96 W to 1800 W to meet the power needs of different equipment. The battery case is made of sturdy, opaque, impact-resistant ABS plastic; the battery cover is firmly connected to the case, and the terminal area is sealed. The six holes on the battery cover are dedicated channels for filling electrolyte during production, after which special pressure relief valves are installed; the pressure relief valves are made of non-flammable material and can regulate internal pressure, improving fire and explosion safety levels.
Internally, both the positive and negative plates are coated with high-performance paste active material, combined with absorbent glass fiber separator technology to achieve efficient recombination of internal oxygen, thereby achieving Maintenance Free operation with no need to add electrolyte and ensuring no free acid. The battery supports horizontal or vertical multi-orientation installation, providing flexibility in installation location. The HR series is designed specifically for high-rate discharge scenarios, providing high specific output power in 5- to 15-minute short-time discharge modes, with power density 30% higher than comparable BP series products, suitable for occasions requiring instantaneous high-current support; it is recommended for uninterruptible power supply systems with backup times within 60 minutes.
Taking HR75-12 as an example, its Rated Voltage is 12 V, and it can provide 300 W of power at a 15-minute discharge rate to 1.3 V per cell; its 10-hour rate Nominal Capacity is 73 Ah. The battery's expected service life can reach 10 years under normal operating conditions, meeting the Eurobat definition of long-life batteries. The capacity range can extend from 4 Ah to 75 Ah depending on different discharge rates, and the power range covers 96 W to 1800 W per battery, with specific values depending on different discharge end-voltage requirements.
HR75-12 has compact dimensions: length 350 mm, width 166 mm, height 174 mm, and Weight approximately 24.75 kg. The Terminal Type is standard B5, with a position designed for easy connection; some models also offer optional I2 Terminal Type to meet different wiring needs. With features such as Maintenance Free operation, high safety, long life, and high power output, HR series batteries are suitable for low-power equipment, uninterruptible power supplies, fire and security alarm systems, emergency lighting and monitoring systems, access control, and precision medical equipment. They can also serve as backup power for power supply networks, the power industry, oil and gas extraction, remote telecommunications facilities, rural estates, hotels and shopping malls, and can be used in the electric vehicle auxiliary power field.
