Product details
The B.B. Battery VRLA battery of the BP4.5-12RTBP series is a 12V maintenance-free valve-regulated lead-acid battery with a capacity of 4.5Ah at a 20-hour rate. This battery features an opaque impact-resistant ABS plastic shell, with the battery cover firmly connected to the shell and the terminal area sealed, ensuring a sturdy and safe overall structure. The terminal type is RT, positioned at the top for easy connection. The six holes on the battery cover are used to fill the electrolyte during production; subsequently, a pressure relief valve made of non-combustible material is installed, which effectively prevents leakage of free electrolyte, provides a high level of fire and explosion safety, and achieves true leak-proof performance.
In terms of technical parameters, besides the 20-hour rate capacity, its 10-hour rate capacity is 4.28Ah and 5-hour rate capacity is 3.83Ah, providing flexible options for applications with different discharge rate requirements. The battery has a compact size: 140mm (5.51 inches) in length, 48mm (1.89 inches) in width, 102mm (4.02 inches) in height, with an overall height of 104mm (4.09 inches), and weighs only 1.78kg (3.92lbs), making it easy to install and deploy in various space-constrained environments. Both positive and negative plates are coated with a paste-like layer. Combined with advanced VRLA technology, the battery has an extremely low self-discharge rate, less than 3% per month, suitable for long-term standby.The battery supports vertical and horizontal installation, providing great flexibility for equipment integration.
The BP4.5-12RT battery is specially designed for low-power backup and continuous power supply scenarios. It is an ideal choice for uninterruptible power supply (UPS) systems in home and small office environments, especially for applications with a recommended backup time of 30 minutes or longer, capable of providing a stable power buffer for critical equipment. In the security field, it can reliably power fire alarm systems, security alarm systems, and surveillance cameras. Additionally, it is also suitable for daily equipment such as emergency lighting, electronic doorbells, remote-controlled cars, and small fans, ensuring their uninterrupted operation.Its maintenance-free feature means no water needs to be added throughout the entire service life cycle, significantly reducing maintenance requirements.
As a member of the BP series, this battery inherits the expected service life of 8-10 years from the series, meeting Eurobat's long-life standards. Its reliability and durability extend its application scope to power networks, power industries, rural real estate, and various places requiring small, stable backup power supplies. Whether used to ensure the continuous operation of medical equipment or as a backup power supply for access control systems, BP4.5-12RT can provide long-lasting and secure power support.
