The EnerSys range of PowerSafe V-TT batteries has been designed specifically for use in applications that demand the highest levels of security and reliability. With proven compliance to the most rigorous international standards, PowerSafe V-TT batteries are recognised worldwide as a premium solution for Telecom applications. The reputation of PowerSafe V-TT batteries for long service life, together with excellent high rate performance, also makes them the number one choice for high integrity, high specification UPS systems. PowerSafe V-TT cells and monoblocs deliver superior performance whilst occupying less space than conventional standby power batteries. The use of V-0 rated, flame retardant, ABS plastic for the thick wall containers and lids offers high mechanical strength with excellent safety features. PowerSafe V-TT batteries are designed using proven gas recombination technology that removes the need for regular water addition by controlling the evolution of hydrogen and oxygen during charging. Oxygen evolved at the positive plates diffuses through microporous separators to the negative plates and, by a series of chemical reactions within the cell, recombines to form water. Each cell incorporates its own safety valve that allows the controlled release of gas when pressure builds up within the cell.
Hawker Water Less batteries are at the leading edge of battery technology, bringing added efficiency to your business and a high level of power and reliability. They're designed to provide more flexibility and more time due to longer topping up intervals of 4, 8 or 13 weeks depending on charging technology. This means reduced labour costs for topping up batteries – up to 60 % (with Hawker 50 Hz chargers) and up to 75 % (with Hawker HF smart chargers). All Hawker Water Less cells use proven PzS technology. The positive electrodes are diecast tubular plates (PzS) and advanced components used in their manufacture provide increased efficiency. The negative plates are flat pasted plates. The separator is of the microporous type. Constructional specifications like a larger electrolyte capacity, a reduced prism height and new flip top plugs ensure added value. In addition, a low electrolyte level indicator fitted on the battery informs you when water topping up is needed. Optional equipment: Aquamatic (automatic water filling system), Electrolyte circulation, Easyplus and Wi-IQ. Easyplus and Wi-IQ are electronic devices that communicate with Hawker HF chargers and deliver the information about battery performance and faults.
