b.b.battery BC42-12(12V42AH)

Product details

The B.B.Battery BC42-12 battery features a 12V voltage output and 42Ah capacity (C20 standard) as its core performance, with a military-grade ABS engineering plastic shell for impact resistance, ensuring stable operation even in extreme environments. Its unique AGM separator technology fully absorbs the electrolyte, enabling truly maintenance-free use, and prevents acid leakage even at a 45-degree tilt or in vibrating environments, making it particularly suitable for installation in space-constrained cabinets or mobile devices. The lightweight design of 12.2kg, combined with compact dimensions of 197×165×171mm, allows flexible deployment in scenarios such as surveillance camera base stations and hospital ventilator backup power supplies.The built-in ceramic filtered pressure relief valve is made of non-combustible materials, effectively preventing safety hazards caused by overcharging, and paired with B2 standard terminals for quick cable connections. The battery has undergone 200 deep-cycle tests, achieving a float service life of 7 years at 25°C, and supports operation in a wide temperature range of -15°C to 40°C. It is now widely used in fields requiring long-lasting and reliable power supply, such as electric vehicle auxiliary power, smart building access control systems, and communication base stations.
