Product details
The BP28-12 is a VRLA battery in the B.B. Battery BP series. BP series batteries are produced as monobloc units covering 4V, 6V and 12V, with capacities from 1.0Ah to 230Ah. The case is made of tough, opaque, impact-resistant ABS plastic, the battery cover is firmly joined to the case, and the terminal area is sealed. The BP28-12 is supplied with a standard B1 terminal type, and T2 I1 terminal types are available as options. The battery cover has six filling holes that are used to fill the electrolyte during production, after which a pressure relief valve made of non-flammable material is fitted; this delivers maintenance free (no topping up required) operation with no electrolyte top-up, ensures leak-proof (no free electrolyte) performance, and provides fire and explosion safety. Both the positive and negative plates carry a high-performance paste coating, and valve-regulated sealed construction keeps self-discharge below 3% per month. The battery supports vertical and horizontal installation and measures 175 mm (6.89 inches) in length, 166 mm (6.54 inches) in width and 125 mm (4.92 inches) in height, with a total weight of about 9.6 kg (21.17 lb). Its nominal capacity is 28Ah at the 20-hour rate, 26.6Ah at the 10-hour rate and 23.8Ah at the 5-hour rate. Under the Eurobat standard, BP series batteries can reach an expected service life of 8 to 10 years under normal operating conditions. The battery suits low-power uninterruptible power supply (UPS) systems, fire and security alarm systems, emergency lighting, surveillance systems and access control, as well as medical equipment, and it is also widely used as backup or main power in power supply networks, the power industry, mining, oil and gas, rural real estate, hotels and shops, and electric vehicles; it is especially suitable for applications that need 30 minutes or more of backup time.
