  • High current drain applications

Storage Battery Details

Reliable and high performance lead acid battery

sealed lead acid battery 12v copper terminal

AGM lead acid battery in series or in parallel connection

Note:

  • To avoid cycle life shortening, it is recommended not to discharge the battery below 50%.
  • We highly recommend installing the battery upright. DO NOT install the battery upside down.
  • It is recommended to connect batteries with the same type (AGM), same voltage (V), and same capacity (Ah) from the same brand.

AGM Battery FAQ

  1. Can you put a AGM battery in any car?

    Yes, it provides the same 12 volts DC to any vehicle that uses a 12 v battery. It’s just a sealed paste and has the same voltage ranges as most 12 volt batteries. It’s still LEAD chemistry.

  2. Can I replace my standard battery with an AGM battery?

    Yes for the most part an AGM is a drop in replacement for your standard Lead Acid Battery. The charging voltages are almost identical.

  3. How can you tell if a battery 12v is AGM?

    Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out.
