Absorbed Glass Mat (AGM) batteries are manufactured as sealed batteries. Most people refer to them as gel batteries. Our BikeMaster Platinum batteries have several things that distinguish them as superior to standard conventional wet batteries and other sealed batteries.

• Completely sealed and maintenance free. This design eliminates the need to add water and prevents corrosion and acid spills on expensive paint and chrome.
  
• Ready to go out of the box. More cranking amperage than the competition. The lack of free electrolyte reduces resistance and produces 25% more cranking amperage then the competition. 2% monthly discharge rate means your bike can sit for an extended peroid of time without constantly monitoring it with a battery charger.
