Product details
BC18-12 serves as the representative model of the BC series of B.B. Battery's VRLA batteries, and is a 12V maintenance-free lead-acid battery. Its nominal capacity reaches 18Ah at a 20-hour rate, providing stable power support for various systems requiring reliable backup power. The battery housing is made of sturdy impact-resistant ABS plastic, ensuring good physical protection. The battery cover is tightly connected to the housing, and the terminal area is specially sealed, effectively preventing electrolyte leakage. It achieves a safe design without free acid, so users do not need daily water addition maintenance. Terminal types include standard B1 terminals, and optional terminals such as T2 or I1 can be selected according to customer requirements to meet different installation and connection requirements.
On the internal structure, the positive and negative plates of BC18-12 are coated with special paste-like active materials and use Absorbent Glass Mat (AGM) technology. This technology enables efficient internal oxygen recombination, converting generated gases back into water, thereby significantly reducing electrolyte loss and achieving a sealed, maintenance-free battery. The pressure relief valve on the top is made of non-combustible materials, which can safely release internal pressure in abnormal situations, providing a high level of fire and explosion safety protection.
This battery is compactly designed with external dimensions: length 181 mm (about 7.13 inches), width 76 mm (about 2.99 inches), height 166 mm (about 6.54 inches), with a total weight of approximately 5.62 kg (12.39 lbs). Its structure is sturdy, allowing installation in horizontal or vertical directions (inversion is prohibited), providing great flexibility for the internal space layout of equipment.
BC18-12 is very suitable as a backup power source for low-power uninterruptible power supplies (UPS), especially recommended for scenarios requiring a backup time of 30 minutes or longer. Its stable output characteristics make it an ideal choice for fire and safety alarm systems, emergency lighting systems, security monitoring systems, and access control systems.Meanwhile, it is also widely used in electronic devices such as medical equipment, fishing lights, and video cameras (VCRs), and can even be used as an auxiliary power source for electric vehicles. Under normal usage conditions, the expected service life of BC series batteries can reach 5 to 7 years. Combined with its wide capacity range of 4.5 to 230Ah, B.B. Battery BC series can meet the various standby and cyclic application requirements from light to medium loads, providing durable and reliable power support for key equipment.
