Gel and AGM batteries-the differences?

Despite the external similarity of structures, GEL and AGM batteries have differences, and significant. It turns out that gel models are more refined. Consider them in more detail.

AGM technology: features

AGM is a battery that functions on absorbent mats. Many experts say that this is the usual fiberglass. But surely no one can say this, because the producers themselves keep this question secret. The peculiarity is that this “fiberglass” holds the electrolyte inside and prevents it from evaporating.

Plates in such models are located close to each other, between them are absorbent mats. This design principle greatly increases battery capacity. Due to the fact that the electrolyte is located inside, the battery can be put as you like. Only one restriction-you can not keep and put upside down. Plates are made of high-quality, pure lead. Due to which, the resistance inside the device is small, and this allows you to quickly charge the battery. you can buy car batteries with delivery to Kiev, Odessa, Kharkov and all over Ukraine on 130.com.ua.

Unattended models are safer: they can be used not only in the car, but also at home. For example, for solar systems. Service life within 5-10 years: depends on operation. Batteries withstand up to 210 discharge cycles to zero, up to 340 cycles — discharge up to 50%, up to 850 discharge cycles at 30%. Especially good AGM-batteries show themselves in the cold.

GEL technology: what you need to know

GEL-not from the word "helium", as is commonly believed, but from "gel". And here we see a completely different design, despite the external similarities. Standardly, there are two sets of plates, but between them there is a special gel that holds the electrolyte inside.

Due to the fact that this gel fills all the space, the plates seem to envelop the electrolyte. Therefore, these batteries have a long service life.

Plates are made of pure lead. On average, the battery serves from 7 years. Accumulators perfectly cope with the discharge in 0-stand up to 400 such cycles. As you can see, the characteristics are very impressive.

Starting currents

Here the advantage is taken by helium models, which are almost 2 times more efficient than AGM batteries. For example: AGM issues up to 700 A., and GEL-up to 1000 A.

But even here the first option will be more practical than conventional devices that can operate on currents up to 400A.

So, batteries are similar lack of liquid electrolyte and the presence of pure lead. However, the basic principle of operation is different: in AGM-fiberglass mats, GEL-the absence of such mats, but the presence of a gel.
