This article will focus on the differences between the main lead acid battery types used in the solar industry.
Agm battery type.
What is agm technology.
Agm stats on sam s duracell 31 group agm marketed as deep cell that many on this post seem to use as a cranking battery.
Wet cell or flooded batteries and absorbed glass mat agm batteries are both considered lead batteries and contain an electrolyte solution which causes a chemical reaction and produces electrons.
Optima batteries are considered spiralcell agm batteries.
The plates in an agm battery can be flat or they can be wound into a spiral.
The short answer is that agm stands for absorbed glass mat which is a specific type of lead acid battery.
Agm stands for absorbed glass mat which is a unique mat designed to trap the electrolyte between the plates inside the battery agm batteries are also known as sla batteries or vrla batteries.
Agm batteries or dry cell batteries are the newest type of battery and can be substituted for wet cell batteries.

The next type of battery to go with is the agm battery which stands for absorbent glass matt.
Agm batteries are common and found in many applications such as rv batteries boat batteries motorcycle batteries atv batteries and ups telecom batteries for generators.
However that doesn t mean the agm setting on a charger is necessarily the correct setting to use on optima batteries or other batteries.
Unlike the traditional wet batteries agm batteries only hold a small amount of acid which is entirely absorbed by the glass mat.
Sla stands for sealed lead acid vrla stands for valve regulated lead acid.
Liquid lead acid batteries or wet cells are the most common lead acid battery type.
For this type of battery the typical absorption voltage range 14 4 to 15 0 volts.
Absorbed glass mat batteries are constructed differently than the traditional flooded battery.
The most proven type of chemistry is the lead acid chemistry.
This is a type of lead acid battery but one where the electrolytes are absorbed into a glass matt.
Agm batteries are safer and more durable when being moved from place to place but can easily be ruined during the charging process.
Typical float voltage range 13 2 to 13 8 volts.
No sulfation or degrading as much as flooded batteries no fiddling with adding water.
Small risk of gas emitting or acid leakage.
This write up covers mainly the concorde sun xtender agm s but also applies to most other brands of deep cycle agm batteries.
However it differs from the conventional or sealed flooded lead acid type.
Every battery type has a different purpose and use case so let s go over the pros and cons of each.
These batteries are recharged when put in contact with a reverse current.
