Heavy-Duty Marine/RV Batteries

It’s so important to be ready because it’s not always blue skies and open roads when you’re away from home. Choosing the right battery can be daunting. Let us help you take the guess work out of finding the right battery.

United Battery offers the latest in Marine/RV battery technology.

Marine Starting Batteries

Built with a durable maintenance free design, these high amp batteries are made to maximize boating convenience with quality and power. Special design features ensure that this no hassle premium performance continues start after start.


  • High cranking power for quick engine starts
  • Flush cover, easy install
  • Extra reserve capacity for emergencies
  • Maintenance free design
  • Flooded design

Dual Purpose Batteries

In many instances, one type of power just isn’t enough to meet the multiple demands of an RV. Dual purpose batteries are the ideal compromise between high starting and moderate deep cycle service which means more accessory power longer run time to handle the many creature comforts of an RV.


  • High starting and deep cycle capability
  • Longer cycling that starting battery
  • Extra reserve power for accessory loads
  • Rugged vibration resistant construction
  • Flooded design

Heavy Duty Deep Cycle

Marine and RV’s have many demanding power drains that can provide a great deal of wear and tear on heavily used batteries. True deep cycle batteries have been especially designed to withstand demanding use.

  • More power for electronics accessories
  • Built-in protection against deep discharge damage
  • Rugged vibration resistant construction
  • Reliable power for modest starting

AGM Deep Cycle Batteries

Here are some of the Features and benefits of (AGM) absorbed glass-mat deep cycle batteries vs. flooded lead acid batteries.

  • Premium maintenance-free starting, cycling and deep cycle service
  • Micro-porous glass mat separators prevent acid spills and terminal corrosion
  • Lower internal resistance ensures higher discharge rates and faster starts
  • 2x the cycle life* extends performance and life
  • 20x more vibration protection* resists wave-pounding
  • Spillproof design enables flexible installation (upside down is not recommended) and safe handling around electronics
  • High freeze-resistance provides better all weather service


Gel Deep Cycle Batteries

Gel batteries offer some of the deepest cycling batteries in the Marine/RV industry. Gel batteries are built to withstand the grueling service of heavy house power or extended times between recharging. These evolutionary maintenance-free batteries deliver dependable performance cycle after cycle while providing longer battery life, even under the toughest marine and RV conditions.

  • Longest deep cycle life
  • Ultimate performance for heavy house power
  • Superior protection against vibration and deep cycle damage
  • Safer install and transport with no-spill design to prevent leaking acid
  • Dependable starting performance
