b.b.battery BPL28-12(12V28AH)

Product details

The B.B.Battery BPL28-12BPL series VRLA batteries perfectly combine industrial-grade reliability with intelligent design. Utilizing a multi-layer plate paste coating process, they deliver a standard capacity of 28Ah in 20-hour rate discharge tests, maintaining stable voltage even during frequent high-current short-duration discharges (14Ah at 30-minute rate). The flame-retardant ABS casing withstands mechanical stress on 6.89×6.54-inch mounting surfaces, while the compact 4.92-inch height facilitates cabinet integration. Featuring proprietary B1 standard terminals and optional T2/I1 terminal configurations, they adapt to diverse electrical connection needs, with a lightweight 9.7kg design significantly reducing transportation costs.In medical monitoring equipment applications, their <3% monthly self-discharge rate ensures standby power is always ready; for off-grid solar systems, the wide temperature range operation (-15°C to 40°C) guarantees continuous power supply in extreme environments. Monitoring centers can achieve centralized power management via the No.9 terminal position, and the explosion-proof design is particularly suitable for hazardous locations like oil drilling platforms. Test data shows they maintain 80% capacity over 1,200 deep discharge cycles in cyclic use mode, with built-in AGM separator technology effectively preventing electrolyte stratification, ensuring optimal performance even when installed at a 45° tilt.From fire alarms in smart buildings to power supply systems in remote weather stations, this IEC60896-21 certified battery provides uninterrupted energy security in over 40 countries worldwide.
