AGM battery: features and benefits

A modern battery is capable of providinga car with a rated starting current for scrolling engine aggregates at any time of the year. Moreover, its charge is quite enough for the long-term operation of the speakers, televisions, connected to the power from the cigarette lighter, and even huge subwoofers. One of these batteries, with which most modern cars are manned, is the AGM-battery. Today we will talk about it.

History of occurrence

The AGM battery was first developed in the 80'syears of the last century by engineers of the world company Johnson Controls Inc. In due time this firm was the leader on manufacture of storage batteries. It was she who first proposed the revolutionary technology of creating launch devices - Absorptive Glass Mat. Literally this phrase is translated as "absorbing fiberglass."

In practice, it was tested on militarycars, after which, since 1985, and to this day in the world serially produced non-serviced AGM-battery. By the way, he found application not only on cars and trucks, but also on many military fighters.

What are the differences?

Externally, this device is no different fromstandard car batteries. The housing is plastic, with two positive and negative polarity terminals located parallel to each other. Their main difference lies in the composition. Under the housing, the AGM battery contains a series of lead plates filled with microporous fiberglass-based material. The latter acts as a sponge that binds the electrolyte. Due to its properties, the microporous material absorbs and retains it, while preventing it from flowing. In this case, the "sponge" is able to hold the electrolyte in any position, regardless of the current location of the battery. The layers of microporous material and the plate of electrodes are located along the entire perimeter of the battery case, thereby filling all of its space. Their arrangement looks like a large puff cake - lead elements are constantly alternating with fiberglass.

Benefits of use

What gives us this characteristic locationplates and microporous material? First, it's safety, because such a battery eliminates the possibility of harmful chemical fumes. Secondly, the AGM-battery is durable. Due to the low discharge threshold and stability to the charge-exchange cycle, its lead plates and electrolyte are less exposed to wear. Thirdly, this battery is very resistant to operation in harsh conditions with constant temperature changes and moisture concentration.

How do I charge an AGM battery?

It's very easy to charge such a battery. To do this, you need to have the appropriate tool (charger for AGM-batteries) and a constant current source of 220 volts. After connecting the terminals in about 18-20 hours, your battery is fully charged. This is signaled by a green light bulb on the body of the device.
