Battery Engineering – the preferred choice by serious sailors for over 60 years.
Double Insulated Positives
The positives are double insulated and sealed in a non-destructive polyethylene envelope
eliminating the cause of most battery malfunctions.
The unique battery design features dual container construction. Each cell is self-contained in a high temperature-retardant, durable polypropylene case that is heat-density unbreakable polyethylene, giving you double protection against breakage or leakage.
The heavier resistor plates put more metal where it counts. This results in more resistance to corrosion and allows for a greater amount of active material. Our exclusive multiplate engineering increases active plate surface by 33% for high discharge rates.
Removable cells permit easy disassembling for carrying your battery onto your boat. Likewise, if a cell has to be replaced, it can be done without special tools or skills.
Rolls batteries have been the batteries of choice by serious sailors for over 60 years. Specifically designed for the marine environment, Rolls batteries have the highest lead content and largest liquid reserve of any other deep cycle battery. This makes Rolls the battery with the longest useful life available.
Choosing the right battery for your particular application will save you money and give you years of trouble-free service
