Although a wet/acid design is initially less expensive and can provide about10% more running time per charge than a sealed battery of equal size, a Wetlead/acid battery has a much shorter service life, requires regular maintenanceand poses a much higher safety risk because of potential battery acid contactand/or explosion. Our sealed battery, instead, provides an inherently safer,truly maintenance-free design. Our batteries provide a significantly longer life-averaging1 to 2 years or longer when...

Advanced technology and the use of the most modern computer-aided design and manufacturing techniques combine to make our sealed batteries the standard by which all other batteries are judged. Our Sealed Batteries are the best the market has to offer.
