  4. AGM Batteries

AGM batteries,

or Absorbent Glass Mat batteries, offer a better temperature range and cycle life with a deep cycle charge/discharge than their lead-acid counterparts, making them ideal for solar systems. They are versatile for many applications such as Marine, RV, backup, etc.

Q/A

  • What size battery do I need?

    We recommend adding all the device wattages used daily and dividing this number by 12V to get a rough estimate on the amount of amperage needed per day.

  • What is the difference between AGM, GEL and Lithium?

    The main difference between these battery types is the price and lifespan. An AGM battery will last approximately 600 cycles, GEL 1100 cycles and Lithium 7000 cycles.

  • Can I wire different battery types and sizes together?

    We recommend wiring batteries that are the same chemistry and amp hour rating. This will limit any efficiency loss due to having different batteries.

  • How do I know if I need to recharge my battery?

    A depleted battery (30%-10%) will read 11.8-11.5 volts and a fully charge battery will read 12.8 volts. We recommend not draining the battery past 50% which is 12.1 volts.
