Product details
Model BPL3.3-12 of B.B. Battery is a valve-regulated sealed lead-acid battery from the BPL Series, a well-designed 12V integrated power solution. The BPL Series batteries offer a wide capacity range, from compact 3.3 Ah to large 210 Ah, meeting power requirements for different scenarios. The battery case is made of opaque and impact-resistant ABS plastic, ensuring structural robustness during transportation and use. The battery cover and shell are integrally sealed through a secure connection, with effective sealing particularly at the terminal area to prevent electrolyte leakage and external contamination. The terminal design varies by series and model, BPL3.3-12 provides T1-type standard terminals, with its precise layout ensuring convenient and reliable connections.
During production, the battery is filled with electrolyte through six holes on the cover, and then a pressure relief valve made of non-combustible materials is installed. This key design not only enables maintenance-free operation without requiring the user to add water, but also ensures no free acid inside the battery through an efficient gas recombination mechanism, fundamentally eliminating the risk of leakage, while providing a high level of fire and explosion safety protection.The battery's positive and negative plates are both coated with a special paste-like coating, combined with absorbent glass fiber separator technology, together achieving excellent electrochemical performance and extremely low self-discharge rate, allowing the battery to retain usable charge even after long-term inactivity.
In terms of physical characteristics, BPL3.3-12 is compact, with dimensions of 134 mm in length, 67 mm in width, 60 mm in height, and an overall height of 66 mm, weighing approximately 1.35 kg. It supports installation in both horizontal and vertical directions, providing flexibility for internal space layout of equipment, but note that it is prohibited from being used upside down. Its nominal capacity is 3.3 Ah at the 20-hour rate and 2 Ah at the 5-hour rate.81 Ah, 1.65 Ah at 30-minute rate, suitable for applications requiring continuous or instantaneous backup power. According to Eurobat standards, this series of batteries has an expected service life of up to 12 years under normal usage conditions, featuring a long-life design.
This battery is an ideal choice for low-power uninterruptible power supply systems, especially recommended for scenarios requiring backup power for 30 minutes or longer. It also finds wide application in fire and safety alarm systems, emergency lighting, monitoring systems, access control, and various medical equipment. Additionally, it can provide stable power for consumer-grade products such as toy cars and fishing lights.Its scope of application also extends to power supply networks, power industry, mining, oil and gas, telecommunication facilities, rural estates, hotel, catering and retail equipment, as well as renewable energy fields, such as energy storage units for solar and wind energy systems, and even as auxiliary power sources for electric vehicles. BPL3.3-12, with its reliability, safety, and ease of installation, has become a trusted choice for numerous applications requiring miniaturized, maintenance-free backup power equipment.
