HR75-12 BB Battery 12V73AH for Telecommunications facilities, Alternative energy systems, Power supply networks and the energy industry, Street lighting and traffic signals, Electric vehicles
HR75-12 is a 12 V valve-regulated sealed lead-acid (VRLA) battery from the B.B. Battery HR high rate series, with a nominal capacity of 73 Ah at the 10-hour rate and a rated power of 300 W/cell at the 15-minute rate. It weighs 24.75 kg. The product uses absorbent glass mat (AGM) technology for efficient gas recombination, is maintenance free (no water replenishment required), and has no free acid (leak-proof battery). It is designed to support high-rate discharge and can be installed in any orientation (do not install inverted). A flame arrestor fitted for safety adds protection, and power density at the 5-15 minute discharge rate is 30% higher than the BP series. The B5 standard terminal type is supplied, with I2 available as an optional terminal type. HR75-12 is suitable for electric bicycles and scooters, golf carts, telecommunications facilities, alternative energy systems, power supply networks and the energy industry, street lighting and traffic signals, electric vehicles, data centers, wheelchairs, and floor cleaning equipment.

Product details
HR75-12 belongs to the HR high rate series of high-power VRLA batteries, which are offered in 6 V or 12 V monobloc formats with per-battery power ratings from 96 W to 1800 W, covering the power needs of different equipment. The battery case is made of tough opaque impact-resistant ABS plastic, the cover is firmly joined to the case, and the terminal area is sealed. The six openings on the cover are dedicated channels used to fill electrolyte during production, and a special pressure relief valve is fitted afterwards. The valve is made of non-flammable material and can regulate internal pressure, which raises the level of fire and explosion safety.
Internally, both the positive and negative plates are coated with high-performance paste active material, and absorbent glass mat (AGM) technology recombines the internal oxygen efficiently. That is what makes the battery maintenance free (no water replenishment required) and ensures no free acid (leak-proof battery). The battery can be installed in any orientation (do not install inverted), including horizontal and vertical positions, which gives flexibility in where it is placed. The HR high rate series is designed to support high-rate discharge: in short 5 to 15 minute discharge modes it delivers a high specific output power, and power density at the 5-15 minute discharge rate is 30% higher than the BP series, making it suitable where a large current is needed for a brief period. It is recommended above all for uninterruptible power supply systems with backup times of 60 minutes or less.
Taking HR75-12 as an example, its rated voltage is 12 V and it delivers 300 W per cell at the 15-minute discharge rate down to 1.3 V per cell; the rated capacity at the 10-hour rate is 73 Ah. Under normal operating conditions the expected service life of the battery can reach 10 years, meeting the Eurobat definition of a long-life battery. Depending on the discharge rate, capacity can range from 4 Ah to 75 Ah and power from 96 W to 1800 W per battery, with the exact figures depending on the end-of-discharge voltage required.
HR75-12 is compact, measuring 350 mm in length, 166 mm in width and 174 mm in height, and weighing about 24.75 kg. The standard terminal type is B5, positioned for convenient connection, and some models also offer the optional I2 terminal type to meet different wiring needs. With its maintenance-free operation, high safety, long life and high power output, the HR high rate series is suitable for low-power equipment, uninterruptible power supply, fire and safety alarm systems, emergency lighting and monitoring systems, access control, and precision medical equipment. It 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 centers, and it can be used for auxiliary power in electric vehicles.
