BC75-12 BB Battery 12V75AH for Emergency lighting and video surveillance systems, Access control systems, Medical equipment, Communication facilities, Alternative energy systems
The BC75-12 is a valve-regulated lead-acid (VRLA) battery from the BC deep cycle series. Its voltage is 12 V, its nominal capacity is 75 Ah at the 20-hour rate, and it weighs 20.2 kg. The standard terminal type is B5, and I2 is available as an optional terminal type. Absorbent glass mat (AGM) technology for efficient gas recombination supports the sealed design, and the battery is maintenance free (no water addition required) with no free acid (leak-proof battery). A flame arrestor fitted for safety and an explosion-proof filter fitted raise the level of protection, and carrying handles for easier installation simplify handling. The battery can be installed in any orientation (inverted position not allowed), so designers can place the unit to suit the enclosure. Typical applications include uninterruptible power supply (UPS) systems, security systems, emergency lighting and video surveillance systems, access control systems, medical equipment, communication facilities, alternative energy systems, power supply networks and the energy industry, street lighting and traffic signals, and data processing centers.

Product details
The BC75-12 is a 12 V valve-regulated lead-acid battery in the BC series, with a nominal capacity of 75 Ah based on the 20-hour rate. The battery uses a sturdy, opaque, impact-resistant ABS plastic case, and the cover is firmly joined to the case to keep the structure integral and durable. The terminal area is professionally sealed to prevent leakage, and terminal design depends on the series and type, providing a reliable electrical connection point.
During production, electrolyte is filled through six dedicated holes in the cover, after which a pressure relief valve made of non-combustible material is installed. This design delivers maintenance free operation, so users never need to add water, and efficient gas recombination keeps the interior free of free acid so there is no risk of leakage. The pressure relief valve maintains the internal pressure balance while providing fire and explosion safety protection.
Inside the battery, both the positive and negative plates carry a specially formulated paste coating, and absorbent glass mat (AGM) technology for efficient gas recombination improves charging efficiency and gas recombination capability, which extends the overall service life of the battery. The BC75-12 weighs about 20.2 kg and supports horizontal and vertical installation, but an inverted position is not allowed at any time.
The BC series covers a capacity range of 4.5 Ah to 230 Ah, and specific capacity values can be read against different discharge rate standards such as C2, C5, C8, C10, C20, and C100. The BC75-12 suits applications that need 30 minutes or more of backup time. It is widely used in low power uninterruptible power supply (UPS) systems, fire and security alarm systems, emergency lighting and video surveillance systems, access control systems, and various precision medical equipment, and it can also serve as an auxiliary or main power supply for electric vehicles.
