Product details
BP4.5-12RT BP series VRLA battery is a maintenance-free 12V sealed lead-acid battery with a nominal capacity of 4.5Ah at a 20-hour rate. This battery uses an opaque impact-resistant ABS plastic casing, with the battery cover firmly connected to the casing and the terminal area sealed, ensuring high structural integrity and leak-proof characteristics, and no free electrolyte inside, making it safe and reliable to use. Both positive and negative plates are coated with high-performance paste-like coatings, combined with a low self-discharge design, with a monthly self-discharge rate of less than 3%, allowing it to maintain sufficient charge after long-term storage.
The battery cover is designed with six filling holes. During production, electrolyte is filled through these holes, and then a pressure relief valve made of non-combustible materials is installed. This design significantly enhances the product's fire and explosion safety. The terminal type is a standard RT top post terminal, positioned according to a universal design for easy connection. With its compact dimensions—length 140 mm, width 48 mm, height 102 mm, total height 104 mm—and a weight of approximately 1.78 kg, it can flexibly adapt to various installation spaces. The battery supports both vertical and horizontal installation methods, providing great convenience for equipment integration.
In terms of technical parameters, BP4.5-12RT provides stable performance at different discharge rates, with a 10-hour rate capacity of 4.28 Ah and a 5-hour rate capacity of 3.83 Ah. As a member of B.B.Battery BP series, which includes 4V, 6V, and 12V integrated batteries with a capacity range from 1.0 to 230 Ah, this model is a reliable choice for low-power scenarios. Under normal operating conditions, BP series batteries can have an expected service life of 8 to 10 years, meeting Eurobat's standards for long-life batteries.
This battery is an ideal power solution for low-power uninterruptible power supplies, fire and safety alarm systems, emergency lighting, monitoring systems, access control systems, and medical equipment.It is also applicable to daily electronic devices such as electronic doorbells, remote control cars, and fans. Additionally, in broader fields such as power grids, the power industry, mining, oil and gas, rural real estate, hotels and shops, and electric vehicles, it can also serve as a reliable backup or main power source. For application scenarios requiring backup for 30 minutes or longer, BP4.5-12RT is a proven recommended choice, ensuring continuous operation of equipment with its long-lasting capacity and stable output.
