AGM Battery

The term in the AGM Batteries (Absorbent Glass Mat) means absorbent fiberglass mesh. The electrolyte is absorbed in a fiberglass mesh between the plates by capillary action. The main features of AGM batteries are:

  • Low self-discharge, can be stored for long periods of time without recharging.

  • Low internal resistance, accept very high load and discharge currents. Large number of cycles: More than 2000 cycles at 30% discharge.

  • VRLA (Valve Regulated Lead-Acid Batteries; lead-acid batteries regulated by valves) therefore without maintenance or gas leakage.

  • AGM Batteries do not have maintenance.

What makes them ideal in applications of high current demand, such as starting engines and traction vehicles that need high current peaks: caravans, quads, jet skis, pallet trucks, golf carts, etc.

AGM Batteries Information

AGM Batteries are a typology of VRLA batteries, since VRLA batteries can be AGM batteries or GEL batteries .


AGM Batteries mean 'absorbent glass separator', as they contain the acronym of: Absorbed-Glass-Mat


Over the years AGM Batteries have become an excellent option for the most demanding solar installations.

Currently in the market there is a wide variety of AGM batteries and depending on the needs of the installation, expected voltage, and end use you can use one type or another of AGM Batteries.


AGM batteries, as previously indicated in the technical characteristics, have an absorbent fiberglass mesh, this mesh absorbs the electrolyte by capillarity.


AGM batteries are characterized by: the low internal resistance accepts very high load and discharge currents, so they will offer us a large number of cycles, as well as the great intensity they offer during the first 5 seconds, which becomes a added value for small engines. In addition, it is a type of popular batteries for its great versatility so we can find them in a wide variety of applications such as: solar systems, jet skis, pallet trucks, golf carts, caravans, child carts, wheelchairs , robotics, alarm systems, telecommunications, medical equipment, auxiliary systems in boats, etc.


It is important to take into account when charging the batteries to select the right charger. If the charger delivers an excessive amount of current, it could overcharge the battery while a good charge will not be made, on the contrary if the charger is very small in addition to taking many hours to charge it, it is likely that it will never charge full. Depending on the type of charge the battery receives, the importance of selecting the correct charger could be irreversibly damaged.


In the solar installations we do not find these problems since the regulators work automatically and always carry out slow loads. When selecting the charger, we usually take a 1-10 equivalence value as a reference. That is, if the battery we have is 150 Ah in C100, the ideal charger will be 15A (150/10 = 15).


AGM Batteries Maintenance

AGM Batteries have a sealed box that prevents spillage and diffusion of gases, so maintenance is zero. Specifically, AGM Batteries do not require or check internal acid levels or their periodic control, although AGM Batteries do require their location in a place protected from high temperatures and extreme weather conditions, so installation in a place of Interior is the best option to guarantee the life and efficiency of AGM Batteries.

It is also important to keep in mind that although AGM Batteries can tip over in a timely manner, the installation must be carried out with the terminals on the top, to ensure the proper functioning of AGM Batteries.


AGM battery installation

WccSolar puts the installation service at your disposal and our expert team of installers travels to your address wherever you are. This service is available for both the AGM battery and the rest of the products on our website, if you wish to receive more information contact us and the WccSolar technical team will advise you according to your needs.


Configuration in the AGM Batteries charge stages


The load voltages can be found mostly in the data sheets in relation to the manufacturer and the technology they use, always good to check the charging voltages of AGM batteries to ensure proper operation. Charging AGM batteries with incorrect voltages can reduce the service life, it is important to always charge them at 100% or never overload and overload AGM batteries.


AGM Battery Warranty


AGM batteries in Wccsolar are guaranteed for 1 years from the date of purchase. Which can give you complete peace of mind when making any battery connection both in series and in parallel but we always recommend putting a battery equalizer for a better balance and full performance.
