Product details
BPL20-12 is a 12V valve-regulated lead-acid (VRLA) battery from the BPL series of B.B. Battery, with a nominal capacity of 20 ampere-hours (20-hour rate). This battery adopts a sturdy impact-resistant ABS plastic case, with the battery cover tightly connected to the case, ensuring good sealing in the terminal area. Its design allows the battery to be installed horizontally or vertically, providing flexibility for equipment integration, but it should be noted that it is prohibited to use it upside down. The battery top cover is equipped with six filling holes, through which electrolyte is injected during production, and then a pressure relief valve made of non-combustible materials is installed.These valves automatically release pressure when internal pressure is abnormal, significantly improving the product's fire and explosion safety levels.
In terms of technology, BPL20-12 employs advanced Absorbed Glass Mat (AGM) technology, achieving efficient internal oxygen recombination, thereby making the battery maintenance-free, so users don't have to worry about water replenishment. Meanwhile, this technology ensures the electrolyte is completely absorbed, with no free acid present, fundamentally eliminating the risk of leakage.The positive and negative plates of the battery are coated with special lead paste, combined with an optimized grid design, which together contribute to its low self-discharge rate, allowing the battery to retain its charge for a longer period during storage.
In terms of electrical performance, the battery has a nominal capacity of 20Ah at the 20-hour rate, 17Ah at the 5-hour rate, and still provides a capacity of 10Ah at the 30-minute rate for high-rate discharge, demonstrating its stable output capability to adapt to different discharge requirements. Its dimensions are 181mm in length, 76mm in width, and 166mm in height, with a total weight of approximately 6.4 kilograms. It has a compact structure, making it easy to deploy in environments with limited space.BPL20-12 is specially designed for medium to long-term application scenarios requiring reliable backup power, especially recommended for systems requiring 30 minutes or longer standby time. It is an ideal choice for low-power uninterruptible power supplies (UPS), fire and security alarm systems, emergency lighting, and surveillance cameras. In addition, it is also widely applicable to access control, medical equipment, telecommunication facilities, renewable energy storage systems such as solar and wind energy, and powering outdoor equipment such as lawn mowers and fishing lights. According to Eurobat standards, BPL series batteries have an expected service life of up to 12 years under normal usage conditions, reflecting excellent durability and cost-effectiveness. The entire BPL series provides from 3.A wide capacity range from 3Ah to 210Ah to meet diverse power requirements. Its specific capacity values correspond to different discharge rates (such as C2, C5, C10, C20, C100, etc.), and users can choose according to actual application conditions. In terms of terminals, BPL20-12 comes standard with Type B1 terminals at position 7, and Type T2I1 terminals are also available as an optional configuration installed at position 6 for easy connection.
