ACDelco Marine/Deep Cycle Batteries are designed and tested for use in demanding marine and recreational vehicle applications.

They use expanded wrought lead calcium grids, which are far more durable and stronger than conventional cast type grids. To handle deep cycle requirements, they also have thicker grids and over twice the active plate material of standard automotive batteries.

This completely sealed design offers you the comfort of no leakage or spills, absolutely essential in any RV or Marine environment. They also come complete with duel terminals for all those accessories, have a built in hydrometer and to add to your safety, use a flame arrester system to prevent the chance of explosion form external sparks.

As this SMF Marine range is designed to deal with the toughest of environments globally, you can be assured with the high crank ratings available we have a model to suit your requirements.

Combining world renowned technology and quality, the Delkor Marine range of maintenance free batteries off­ers the boating enthusiast a truly hassle-free battery for peace of mind.

U.S. Battery Company is the industry leader in manufacturing quality “true” deep cycle batteries specifically for: electric golf cars, access equipment, materials handling, marine, RV, solar power, renewable energy, sweepers, scrubbers, and many other deep cycle battery applications. U.S. Battery Company has been building flooded lead acid batteries since 1926 and are 100% manufactured in the USA including the 6-volt, 8-volt & 12-volt deep cycle range. US Batteries are built with XC Diamond Plate Technology making US Batteries the best choice for applications where batteries are subjected to deep discharge and fast recharge on a daily or regular basis.

XC Diamond Plate technology;
Xtreme Capacity

  • Highest initial capacity
  • Fastest cycle up to full rated capacity
  • Highest total energy delivered over the life of the battery.
  • Ultimate compatibility with the wide range of chargers used in the field
  • High Charge efficiency

By installing a Fullriver AGM battery in your RV, camper trailer, or caravan you can take battery watering off your maintenance list and focus on more important things like relaxing.

Fullriver DC Series AGM Batteries are designed and constructed to make sure you can focus on the road ahead by providing consistent, reliable power to the full range of accessories you’ve added to make your time away from home feel like you took your home with you.

Fullriver’s well-proven track record has seen this product become the industry benchmark for longer service life in deep-cycle applications. What the others claim, Fullriver actually delivers.

Fullriver Deep-Cycle GEL batteries are also maintenance free and require no servicing, while providing you with the unmatched quality and extended cycle life of Fullriver’s advanced Silica-Gelled electrolyte battery technology.

When you’re out at sea or living on the road you want reliable power that won’t slow you down. RELiON Lithium Iron Phosphate (LiFePO4) batteries offer lightweight, safe and high-power energy solutions for all types of marine and recreational vehicles.

RELiON’s Deep Cycle LiFePO4 batteries are far more functional than lead acid alternatives, charging at nearly 100 percent efficiency. A Relion lithium battery will have you charged up and arriving at your next destination before a lead acid battery would even have time to charge.

Built to last, Relion LiFePO4 batteries will even outlast the vehicle they’re installed in, ensuring you receive the best value for your investment.

Lithium’s efficiency is also helpful when you’re storing solar power. Perhaps you’re trying to charge your battery before the sun goes down. With a LiFePO4 RV battery, you get the maximum amount of energy from your solar panels, so you have more than enough power by the time night falls.

Choose from the World’s Most Powerful Deep Cycle & Marine Batteries
