Product details
BC120-12 belongs to the BC series of VRLA valve-regulated lead-acid batteries made by B.B. Battery. The series is offered in 6 V and 12 V overall voltages with capacities ranging from 4.5 Ah to 230 Ah. The case of BC120-12 is made of sturdy, opaque, impact-resistant ABS plastic; the lid is firmly connected to the case and the terminal area is sealed to prevent leakage. Terminal design depends on the specific series and model, which ensures reliable connection.
During production, electrolyte is filled through six specific holes in the battery lid, after which a pressure relief valve made of non-combustible material is installed. This design guarantees a very high level of fire and explosion safety and also makes the battery completely maintenance free: users do not need to top up water periodically, and there is no free acid inside, so it is a leak-proof battery. Thanks to the sealed construction and safety design, BC120-12 can be safely installed horizontally or vertically (inverted position not allowed), which gives flexibility in equipment layout, and the carrying handles make installation more convenient.
In terms of performance, BC120-12 has a nominal voltage of 12 V and a nominal capacity of 120 Ah at the 20-hour rate. The battery uses pasted plates and absorbent glass mat (AGM) technology to achieve efficient gas recombination, which extends battery life and maintains stable performance. Under normal float service conditions, the expected service life of the BC series is 5 to 7 years. Its physical dimensions are 407 mm long, 173 mm wide and 210 mm high (total height 239 mm), and the weight is about 35 kg.
BC120-12 is an ideal choice for a variety of critical standby power applications and is well suited to low-power uninterruptible power supply systems, fire and security alarm systems, emergency lighting, surveillance systems, access control and various types of medical equipment; it is especially recommended for scenarios that need 30 minutes or more of backup time. In addition, the series batteries can also serve as auxiliary or motive power supplies for electric vehicles, and their reliable design, long service life and wide application adaptability make them a trustworthy power solution in fields such as telecommunications, data centers and industrial backup power.
