Renewable Energy Batteries
Rolls Renewable Energy Solar Batteries

Rolls Marine heavy duty design has a reputation for outlasting all competition, at sea where the life of the boat and her crew are at stake, take no chances, specify Rolls! No other manufacturer offers more for your money!

• Environmentally Friendly - NO ACID LEAKAGE: The new generation of batteries utilizes dual container construction. Each cell is assembled in its own inner container made of high temperature retardant, durable polypropylene with the inner cover heat bonded to the container, (thus acid leakage is eliminated). The cells are then assembled into a high density tough polyethylene outer container with a removable lid. Even if the outer container were to break the battery would still be operable without the harmful affects of sulphuric acid spills.

• Enveloped Positive Plates - The positive plates are doubled insulated. The first layer consists of a thick woven glass mat. The plate and matting are then sealed in a non-destructible, microporous, polyethylene envelope. The envelope eliminates the possibility of separator misalignment, cracked separators, treeing, or shorting at the bottom or sides. The sediment chamber is eliminated allowing more liquid space above the top of the cell, thus lengthening periods between watering.

• Rugged Plate Construction - Our Rezistox Plate Design uses fewer, but heavier, members in the grid (current carrying conductor). More metal where it counts. The heavier members offer more resistance to positive grid peroxidization (corrosion), and allow for greater percentage of power producing active material. (The grid and active material are referred to as the plate.)

• Optional Cell Connection - Cell replacement is now less frequent, but if necessary, Rolls makes it clean and quick. As an option the individual cells can be bolted together allowing the battery to be repaired, or assembled on location. Cell replacement can be accomplished without special skills or tools.

Recombiner Caps
Rolls Marine Batteries come with optional extra "Recombiner Caps". They are placed on top of the battery in replacement of the standard cell caps. When the battery gas rises up to the recombiner caps, a catalyst produces water from the gas and gently drips back into the battery. This dramatically reduces the maintenance as you should only have to top up the battery 1 or 2 times a year!
