What is an AGM battery: Background on absorbed glass mat battery products. In this battery design, acid is completely absorbed into microfiber glass mat separators which are sandwiched between lead plates and typically wound in coils. Advantages:

  • totally sealed and maintenance free design
  • more heat and vibration resistant
  • slower self discharge rate (longer shelf life). A wet battery discharges 15% a month, some AGM batteries discharge only 2-3% a month, so 6 months idle is no problem

Many vendors are online.
