Product details
The BP3-12 battery is a product in the B.B. Battery BP series, which offers 4-volt, 6-volt, and 12-volt monolithic designs with capacities ranging from 1.0Ah to 230Ah to meet power needs in different scenarios. This battery uses a sturdy, impact-resistant ABS plastic case for excellent durability; its cover is tightly joined to the case, and the terminal area is fully sealed to effectively prevent leakage. Terminal design depends on the specific model; the BP3-12 offers the T1 standard Terminal Type and an optional T2 terminal, allowing flexible installation positions. The six filling holes on the battery cover are used to fill electrolyte during production, after which pressure relief valves made of non-flammable material are installed, a design that greatly enhances the battery's fire and explosion safety.
Internally, both the positive and negative plates of the BP3-12 are coated with a specially formulated paste; combined with advanced Valve Regulated Lead Acid (VRLA) technology, this makes the battery Maintenance Free, so users do not need to add electrolyte, while achieving complete leak protection with no free electrolyte present. The battery's self-discharge rate is very low, less than 3% per month, ensuring long storage performance. Another outstanding advantage is support for multiple vertical and horizontal installation orientations, providing great flexibility for space layout inside equipment.
In terms of technical parameters, the BP3-12 is a 12-volt battery whose Nominal Capacity is 3Ah at the 20-hour rate, 2.85Ah at the 10-hour rate, and 2.55Ah at the 5-hour rate, meeting Eurobat standards for long-life batteries. The battery weighs approximately 1.32 kg (2.91 lb) and has compact dimensions: length 134 mm (5.28 in), width 67 mm (2.64 in), height 60 mm (2.36 in), and total height 66 mm (2.6 in), making it easy to integrate into various devices.
BP series batteries, including the BP3-12, are known for reliability and long life, with an expected service life of up to 8 to 10 years under normal operating conditions. This makes it an ideal power choice for many critical applications. It is well suited to powering low-power Uninterruptible Power Supply (UPS) systems and is especially recommended for scenarios requiring 30 minutes or more of backup time. At the same time, it provides stable and lasting power in security and fire alarm systems, emergency lighting equipment, access control systems, and important medical equipment. Its applications also extend to general power packs, remote-controlled model cars and model aircraft, and it can even serve as a reliable backup power source in power supply networks, the electric power industry, mining, oil and gas, rural properties, hotels, and shops.
