VRLA AGM batteries are one of the two broad types of SMF batteries. They are so called because they use absorbed glass mat (AGM) as separator. AGM is a porous glass mat separator with the ability to absorb a large amount of electrolyte while still allowing some pores to be unfilled. These empty pores act as channels for oxygen to move from the +ve plate to the –ve plate. That is why these batteries are called VRLA AGM batteries.

Advantages of VRLA AGM batteries are:

  • Widest temperature range of all the battery types
  • Lowest self-discharge rate of all the battery types
  • Best shock/vibration resistance of all the battery types
  • Best performance for high power applications
  • Less expensive than VRLA Gel batteries

Disadvantages of VRLA AGM batteries are:

  • Don’t perform as good as flooded or VRLA Gel batteries in regular deep discharge (>80% DOD) applications
  • Don’t perform as good as VRLA Gel batteries in low power applications

We have a wide range of VRLA AGM batteries, which are specifically tailored for various types of applications.
