What is AGM on a battery mean?

absorbed glass mat
An AGM (absorbed glass mat) battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. This material’s design enables the fiberglass to be saturated with electrolyte – and to store the electrolyte in a “dry” or suspended state rather than in free liquid form.

How can you tell if a battery is AGM?

And then the labels of the AGM lead-acid batteries should state “AGM” or, in full words, “Absorbed Glass Mat,” or terms such as: “dry cell,” or “sealed regulated valve,” or “non-spill,” or “regulated valve” on the label. However, telling an AGM apart from a gel cell is difficult if there is no labeling.

What is Mercedes AGM battery?

Not to be confused with the AMG performance brand by Mercedes-Benz, AGM batteries are designed to eliminate electrolyte movement by holding it in place, reduce battery maintenance, and are claimed to have more charging power, among other benefits.

What are the different types of AGM batteries?

AGM battery: There are two types of AGM batteries – lead-calcium and Thin Plate Pure Lead (TPPL). Lead-calcium: Lead-calcium AGM batteries have many of the operating limitations of the flooded, wet cell battery, but without the hazardous issues. They are single purpose in function and design.

Is a deep cycle battery an AGM battery?

Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte absorbs into a fiberglass mat. The internal resistance of AGM batteries is lower than traditional cells, they can handle higher temperatures, and self discharge more slowly.

Is an AGM battery considered deep cycle?

AGM Batteries Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte absorbs into a fiberglass mat. The internal resistance of AGM batteries is lower than traditional cells, they can handle higher temperatures, and self discharge more slowly.

Does an AGM battery need to be vented?

Even though AGM batteries are considered to be maintenance-free, they still require venting. If you overcharge the battery or charge it too quickly for the absorption mat to keep up with, the same dangerous build-up of hydrogen gas can occur.
