Product details
BP4.5-12RT is a 12V valve-regulated lead-acid battery from B.B. Battery's BP series, with a nominal capacity of 4.5Ah at a 20-hour rate. This battery uses an impact-resistant ABS plastic shell, which is sturdy and durable. The battery cover is firmly connected to the shell, and the terminal area is sealed to effectively prevent leakage, ensuring no free electrolyte inside. Its top post terminal design facilitates installation and connection. The six filling holes on the battery cover are used for filling electrolyte during production, followed by installing a pressure relief valve made of non-combustible material, which provides high-level fire and explosion protection for the battery. Meanwhile, it is maintenance-free, and users do not need regular water replenishment.
In terms of technical parameters, the capacity of BP4.5-12RT varies with different discharge rates, with a 10-hour rate of 4.28Ah and a 5-hour rate of 3.83Ah, providing flexible options for different load requirements. The battery features low self-discharge, with a monthly self-discharge rate below 3%, making it suitable for long-term standby. With a compact size design, measuring 140mm in length, 48mm in width, and 102mm in height, and weighing approximately 1.78kg, it supports vertical or horizontal installation, saving valuable space for equipment integration.
This battery is an ideal choice for low-power uninterruptible power supply systems, especially suitable for applications requiring backup for 30 minutes or longer.Its reliable performance has made it widely used in fire and safety alarm systems, emergency lighting, monitoring systems, electronic access control, and medical equipment. Additionally, it is also suitable for consumer electronics such as remote control model cars and fans, providing stable power support for power supply networks, the power industry, rural real estate, and hotels and stores. Under normal usage conditions, BP series batteries have an expected service life of 8 to 10 years. Combined with the long-life design under Eurobat standards, it ensures the economy and reliability of long-term use.
