A single model's specification table often shows several capacity figures, corresponding to the 20-hour, 10-hour and 5-hour rates and other discharge conditions, with some tables also listing the 30-minute, 2-hour and 8-hour rates, 1-hour rate capacity and 15-minute rate rated power. The figures do not contradict one another; they describe the same battery over different backup durations. Before ordering, establish the backup duration the system needs, then check the capacity item for the corresponding condition.
For buyers and engineers working on UPS, telecommunications, solar storage, security and medical systems, this note sets out the points to confirm before ordering: voltage and capacity first, then terminal type, then mounting method and load-bearing capacity, and finally whether a long-life or high-rate series is needed. The terminal types and series listed come from BB Battery's existing product line, and the parameter table can be used to compare model specifications item by item so that nothing is missed at ordering.
BB Battery lists 19 lead-acid battery series, covering general purpose, long life, high rate, deep cycle, electric, front terminal and gel directions. This note sets out what each series is for across uninterruptible power supplies, telecommunications facilities, data centres, security, medical equipment, alternative energy, road lighting, e-bikes and scooters, wheelchairs, golf carts and mowers, and gives a checklist for narrowing the range to two or three series before comparing capacity, dimensions and terminals.
