ROLLS BATTERY ENGINEERING - #1 FOR 40 YEARS!

Marine Batteries

Rolls Marine Batteries have been the #1 CHOICE of the people who ply the North Atlantic for over forty years. The heavy duty design, with a reputation for outlasting all of the competition, is known from Texas to Newfoundland. At sea, where the life of the boat and her crew are at stake, take no chances, specify Rolls. And for RV owners, nothing beats the dependability and deep cycle capacity of a Rolls Marine Battery in your well-outfitted vehicle.

Series 3000 - Heavy Duty Marine (click for specs)

Designed for starting applications and suitable for limited lighting and power service. These batteries have maximum plate area without sacrificing life and reliability. Premium high density positive and negative plates along with lifetime microporous polyethylene envelopes are used.

Series 4000 - Deep Cycle Marine (click for specs)

Designed for lighting and power and suitable for starting applications. This is a cycling battery and has more cubic inches of positive active material. These have maximum plate thickness that does not sacrifice on performance.

Series 5000 - Deep Cycle Multiplate Marine (click for specs)

The same features as the Series 4000 plus the multiplate design available in the NS & CH types. forty percent more plate area than conventional designs give the Rolls Series 5000 the highest cranking capacity in the industry. Because of increased plate area the NS & CH types have the lowest current density per plate for a comparable load of any other marine battery on the market. This results in less grid oxidation which produces a much longer life.

THE ROLLS DIFFERENCE

RESISTOX POSITIVE PLATE - Over thirty years development and experience are behind the famous Resistox Positive Plate Design. Rolls batteries made with Resistox outlast other same-size marine batteries with up to 2X Greater Life.

HIGH-DENSITY ACTIVE MATERIAL - Retards active material shedding, thus greatly prolonging the useful battery life.

FIBERGLASS MATS - A dense glass mat will prevent shedding of the positive plate material. Such a heavy, dense mat is used in the Rolls Series 3000, 4000 and 5000 lines - not a thin loose weave like that used in competitive batteries to qualify as double insulation. Such attention to quality is a hallmark of the entire Rolls line.

SEPARATORS - The positive plates are double insulated with thick woven glass matting and then sealed in a non-destructive microporous polyethylene envelope. The envelope eliminates the need for a sediment space at the bottom of the cell, and allows for more liquid space at the top.

HIGH-DENSITY NEGATIVE PLATE - High-Density negative material is essential in order to maintain a perfect balance with the high-density positive material. This also eliminates negative starvation and maintains a healthy negative plate throughout the life of the battery.
