Product details
The BC75 - 12BC series battery is a valve - regulated lead - acid battery produced by B.B. Battery, offering overall voltage options of 6V and 12V. It has a wide capacity range from 4.5Ah to 230Ah, which can meet the power requirements of different applications. The battery case is made of sturdy and durable opaque impact - resistant ABS plastic, ensuring good physical protection for the battery during daily use and transportation. The connection between the battery cover and the case is very firm, and the terminal area has been specially sealed to effectively prevent electrolyte leakage and intrusion of external impurities. The specific design of the terminals varies according to the series and type of the battery to adapt to various connection requirements.During the production process, the electrolyte is injected through six filling holes on the battery cover, and then a specially designed pressure relief valve is installed on each filling hole. These pressure relief valves are made of non - flammable materials and can safely release gas when the internal pressure of the battery rises abnormally, thereby significantly improving the fire and explosion - proof safety level of the product and ensuring the safety of the usage environment.
Both the positive and negative plates inside the battery are coated with high - performance paste - like active materials, which helps to stabilize the electrochemical reaction and extend the cycle life.Thanks to its valve-controlled sealed structure, BC75-12 is a truly maintenance-free battery that requires no electrolyte addition or water replenishment by users throughout its entire service life. Meanwhile, there is no free acid inside the battery, completely eliminating the risk of leakage, allowing users to safely install it in various devices. Another major feature is high installation flexibility; the battery can be safely installed in horizontal or vertical orientations, though it should be noted that inversion is prohibited, which greatly facilitates the internal space layout of the equipment.The absorbent glass fiber separator technology used inside the battery can efficiently achieve oxygen recombination, converting the generated gas back into water, thereby effectively suppressing electrolyte loss and maintaining long-term stability of battery performance.
In terms of technical parameters, taking the model BC75-12 as an example, it is a 12-volt battery with a nominal capacity of 75Ah at the 20-hour rate. The battery weighs approximately 20.2 kilograms (44.53 pounds) and has dimensions of 350 mm (13.78 inches) in length, 166 mm (6.54 inches) in width, and 174 mm (6.85 inches) in height, with a compact structure.Terminal types include the standard B5 terminal, and some models may offer optional terminal types such as I2 to meet different wiring requirements. According to Eurobat general standards, the BC series batteries have an expected service life of 5 to 7 years under normal operating conditions. Their capacity ranges from 4.5Ah to 230Ah, and specific capacity values such as C2, C5, C10, C20, etc., are defined according to different discharge rates. Users can refer to the detailed specification sheet when selecting models.
This battery is very suitable for applications requiring a reliable backup power source. It is an ideal choice for low-power uninterruptible power supply systems, fire alarm and security systems, emergency lighting equipment, monitoring systems, and access control systems.In the medical equipment field, its stable power output and high safety standards can also provide strong support. Additionally, it can serve as a power source for electric vehicles. It is particularly recommended to use this series of batteries in backup applications requiring 30 minutes or longer standby time. Its long-lasting discharge performance and long-life characteristics ensure the continuous operation of critical systems. Whether for commercial security, infrastructure protection, or professional equipment power supply, the BC75-12BC series VRLA batteries provide a safe, maintenance-free, and flexibly installable power solution.
