Best AGM Batteries for 2023 - BestForDriver (2023)

There are many reasons to choose the best AGM battery for a car instead of the lead-acid flooded or gel batteries. So what is an AGM battery? The abbreviation goes for “absorbed glass mat”. The place between the plate and wrappers is filled with the fiberglass that forms a peculiar cellular web. It keeps the electrolyte within by capillary action.

The battery always holds its contents inside and is secured against any leakage. The electrolyte would not spill (as it would in the flooded lead-acid batteries) preserving the battery capacity and saving the nearby area from burning. The battery posts don’t get sulfated, while the battery and car parts don’t suffer from corrosion.

Such a dense structure provides for the steady operation of the absorbed glass mat car battery in any conditions and any position, too. It may be rotated on its side or upside down without affecting its function or capacity. It also ensures the minimal liquid evaporation that is frequent in flooded and even gel batteries in hot temperature. That’s what justifies it as the best AGM battery — it’s maintenance-free mode.

The innovative structure design of the best AGM car battery enables it to produce a higher voltage and in less time than gel or flooded batteries. It also gets recharged very quickly.

  • AGM vs Lead Acid
  • How Long Do AGM Batteries Last?
  • Are AGM Batteries Better than Gel Ones?

AGM: Brief Description

The technology dates back to 1980s and first sealed lead acid power banks. The inside structure is made of the fiberglass absorbing the electrolyte. The plates can be put flat or cylindrically. This battery has a high conductivity that is protected by a low internal resistance. It doesn’t grow sulfation on plates and posts and is maintenance free. AGM batteries take charge fast and can be drained up to 80% of their capacity.

AGM vs Lead Acid — Which One to Choose?

The AGM is a type of the lead-acid battery. However, it differs from the conventional (or sealed) flooded lead acid type:

  • Safety. Small risk of gas emitting or acid leakage.
  • No maintenance. No sulfation or degrading as much as flooded batteries, no fiddling with adding water.
  • Power. Better conductivity faster charging with the constant voltage.
  • Shelf-life. Can be kept out of operation longer preserving the perfect conductivity.
  • Bigger cycle. Deep-cycle batteries can be recharged several times.

How Long Do AGM Batteries Last?

The enhanced chemical structure of the AGM battery provides for its longer life cycle. They are supposed to serve without issues for three to five years. The heavy-duty models and the properly maintained ones can reach eight and even ten years of life. The battery-damaging factors are the following:

  • Extreme weather conditions. AGM batteries work well in heat or cold, but the capacity can be deteriorated.
  • Bottom-level discharge. Getting the battery flat will decrease its operational efficiency.
  • Incorrect charging. Improper feeding leads to overcharging and kills the battery.

Are AGM Batteries Better than Gel Ones?

The AGM envisions a certain chemical structure containing electrolyte. The Gel power banks preserve the electrolyte in silica gel cells. Both AGM and Gel batteries are spill-proof, vibration-resistant, have a low level of self-discharge, can be discharged up to 60% capacity preserving their capacity and charging properties. The difference lies in:

  • Type of operation. The AGM ones are more efficient at cranking amps. The Gel can handle the floating charge better.
  • Weather conditions. Gel batteries are less subject to extreme temperatures.
  • Size. With the same capacity, the AGM batteries are smaller.
  • Price. AGM banks are cheaper.
