558-AH Battery


EnerSys has expanded its NexSys product line to include the NexSys® 558-AH battery. It consists of six NexSys® 12-volt 186-AH blocs connected in series/parallel to achieve 24-volts and 558-AH. This setup provides the ability to charge at rates between 32 and 70 percent of the battery’s capacity for fast and flexible opportunity charging. The NexSys® 558-AH battery is constructed from Thin Plate Pure Lead (TPPL) and features compressed Absorbed Glass Mat (AGM) plate separators with high electrolyte absorption and stability to enhance cyclic capability and provide extreme vibration resistance. The battery is virtually maintenance-free as it does not require watering. The exceptional charge acceptance characteristics of TPPL batteries allows for rapid charging during shift breaks, extending the battery run times well beyond conventional industrial batteries. 

The NexSys® 558-AH battery measures at 30.35 inches in height, 12.77 inches in width, 25.35 inches in length and will fit many 24-volt, Class III lift trucks. Because the battery can be charged at such fast rates, it requires the use of EnerSys® EnForcer® chargers, which have higher efficiency ratings compared to many conventional chargers. “The NexSys® 558-AH battery allows for reduced recharge time and provides a faster power solution for a number of warehouse and manufacturing applications that utilize pallet trucks,” says Steve Spaar, director of marketing for EnerSys. “The battery’s advanced design, combined with robust material construction, allows us to offer our customers an energy solution with exceptional flexibility that is ideal for multi-shift operations.” Complementing its virtually maintenance-free characteristics, the NexSys® 558-AH battery withstands shock and vibration while providing eco-friendly performance. Its minimum gassing makes it ideal for use in shops, public areas and sensitive warehousing areas. Additionally, NexSys® batteries typically occupy up to 30 percent less space than equivalent conventional lead acid batteries due to the thin plate design’s high energy density properties. NexSys® batteries have a long shelf life – up to two years.
