The Rolls Big Red Battery has an expected life of up to 20 years!
The "Big Red" uses 2 Volt cells to make a large 4 or 6 volt battery.
High performance Rolls / Surrette construction, with a nonbreakable container to eliminate breakage due to rough handling and abuse. The dual container construction of the Big Red battery means each cell has a durable polypropylene inner container which eliminates breakage due to rough handling and abuse, acid leakage and short circuits due to the accumulation of moisture, dirt and other foreign objects.
The cells are then assembled into a high density, tough, polyethylene outer container with a removable lid. The Big Red batteries are designed specifically for solar charging and other renewable energy applications. They are quality manufactured to offer up to 20 years of life, thanks in part to their non breakable, dual container construction. 10 year prorated warranty.
The dual wall construction give the Big Red battery line a better low temperature tolerance than most flooded lead acid batteries. However, it is still important to keep the ambient temperature as close to 20°C as possible.
