Product details
BP33-12 Standard Type is a reliable product in B.B. Battery's VRLA Battery Series, designed for a variety of application scenarios requiring a stable backup power source. As a 12V integral valve-regulated sealed lead-acid battery, it features a maintenance-free design, requiring no electrolyte addition throughout its entire service life, and has excellent leak-proof performance to ensure a clean and safe environment around the equipment. Its low self-discharge rate is less than 3% per month, allowing the battery to maintain its charge for a long time during storage or standby, ready to operate at any time.
The nominal capacity of this battery is 33Ah at a 20-hour rate, providing durable and stable power support for the equipment.Its sturdy shell is made of impact-resistant ABS plastic, with the battery cover tightly sealed to the shell, effectively protecting the internal structure. The B7 standard terminal on the top is convenient and reliable for connection. The dedicated liquid injection hole on the battery cover is installed with a pressure relief valve made of non-combustible material after production, which not only ensures the safe release of internal battery pressure but also provides high-level fire and explosion safety protection, giving users greater peace of mind during use.
The design of BP33-12 fully considers installation flexibility, supporting both vertical and horizontal installation methods, and can easily adapt to the limitations of various cabinet and equipment space layouts.Its compact size, with a length of 195mm, width of 129mm, height of 155mm (total height 179mm), and self-weight of approximately 11.25kg, makes it easy to integrate into existing systems.
In terms of performance and lifespan, this battery has an expected lifespan of 8 to 10 years under normal usage conditions, meeting Eurobat's definition of long-life batteries. It is not only an ideal choice for low-power uninterruptible power supplies (UPS), telecommunication systems, network switch cabinets, and security alarm systems, but also particularly suitable for applications requiring 30 minutes or longer of backup. Meanwhile, it is widely used in medical equipment, photovoltaic energy storage systems, emergency lighting, and light electric vehicles such as golf carts.In addition, in scenarios with high power supply reliability requirements such as the power industry, oil and gas extraction, rural residences, hotels, and commercial premises, BP33-12 can also serve as a reliable backup or main power source.
