Valve-regulated lead-acid batteries

Authorised Yuasa battery distributor Gresham Power Electronics, the Salisbury-based Defence and Commercial power conversion specialist, announces the availability of two series of high reliability valve-regulated lead-acid batteries (VRLA) batteries (valve-regulated lead-acid) from Yuasa’s wide industrial product range.

Valve-regulated lead-acid batteries are more commonly known as sealed or maintenance free lead-acid rechargeable batteries which, due to their construction, may be mounted in any orientation and do not require constant maintenance.



The term ‘maintenance free’ is a small misnomer as all valve-regulated lead-acid batteries batteries still require cleaning and regular functional testing. Batteries from Yuasa are the engineer’s choice for even the most critical standby applications.

The Endurance Range of batteries offer 2, 4 & 6 Volt outputs rated from 80Ah to 540Ah Suitable for all standby applications including telecommunications, UPS and emergency lighting.

Both families meet Eurobat (Association of European Automotive and Industrial Battery Manufacturers) Classifications.

The ENL range is suited to general use and has a 15 year design life in standby conditions. The EN series provide high rate discharge performance and a long life of over 12 years.

Other common features include: unique mix and match parallel assembly allowing extensive variations to network capacity, electrolyte suspension – A.G.M. technology – assures there is no free electrolyte to spill or leak, high gas recombination efficiency eliminates the need for forced ventilation and separate battery rooms, case Material Oxygen index 30 and fully compliant with BS6290-4 and IEC896-2.
