AGM battery mainly uses its high performance combined with Auto Start-stop technology. However, even if the car does not have a start-stop system, the advantages of the AGM battery can be used: Auto Start-stop technology provides a greater power reserve, and traditional vehicles can also benefit from it, for example due to the longer battery life.

Advantages of Auto Start-stop technology

In addition to the advantages already mentioned, there are other reasons to upgrade to AGM batteries. It is recommended to replace the AGM battery in the following situations:

  • Large short trips of less than 10 kilometers or annual mileage of less than 10,000 kilometers do not allow the alternator to have enough time to fully charge the battery. Every time the battery is not charged to the full SOC (state of charge), the more difficult it is for the battery to start the vehicle next time.

  • If the vehicle is only used on a seasonal basis, the old traditional starter battery may discharge prematurely. This is especially true if there are unfavorable conditions in the storage location and the battery charger is not being used to keep it charged. AGM batteries can better withstand long downtime, because with Auto Start-stop technology, the electrolyte isolated in the diaphragm will not be stratified, thereby reducing sulfide. This means that AGM batteries are easier to charge than wet batteries after a long period of shutdown.

  • AGM batteries can also withstand extreme external temperatures and have high power reserves. The traditional starter battery’s response to extreme heat and cold causes a rapid decrease in capacity and a faster discharge.

  • If the vehicle is equipped with a large number of non-standard electrical equipment, these equipment will increase the power consumption, for example: AGM battery is a complex audio system that can provide the necessary power for the vehicle that cannot be provided by traditional wet batteries.

AGM Batteries – The first choice for light commercial vehicles

In commercial use, vehicles are often used for multi-shift operations. AGM batteries can withstand higher loads during multi-shift operation better than ordinary starter batteries.

City trucks are usually also equipped with electric parts and special equipment. Due to the decomposition of active materials related to its capacity, conventional starter batteries quickly reach their limits and deteriorate. Due to the special design of the battery and the special mixture of active materials, AGM batteries can withstand more and deeper charging cycles than traditional batteries.

Automatic start-stop systems are more effective with an AGM battery

Vehicles that are equipped with a simple start-stop system and do not need to reclaim braking energy (recovery) are usually equipped with EFB batteries. However, even in this case, it is worthwhile to replace the AGM battery: Auto start-stop technology is reliable and trouble-free. Last but not least, the high load capacity of AGM batteries is impressive: During their entire service life, AGM batteries have better charge acceptance than EFB batteries.

SEPARATING AGM BATTERY FACTS FROM THE MYTHS

AGM eliminates acid spilling in an accident because it is sealed. They can be installed at odd angles.

Have you noticed that more batteries are moving under the trunks and seats of some vehicles? If the battery is not under the hood, it is most likely an absorbent glass mat (AGM) or gel battery. Since AGM is sealed, it can avoid acid spills in accidents. They can be installed at strange angles.

These batteries are powerful due to their size and weight, which allows manufacturers to reduce the weight of the vehicle by several pounds. This is an important reason why they are increasingly appearing on new vehicles. In addition, these batteries have a larger backup capacity to support stop/start systems and flameout functions.

Here are the four AGM myths that you may have heard.

1)You can use your regular battery charger on AGM or gel cell batteries.

Due to the difference in internal resistance, these batteries like to charge slowly.

Many AGM battery chargers have a microprocessor that collects information from the battery and adjusts the current and voltage accordingly. Some have different settings to charge flooded batteries or AGM batteries. Overcharging will kill these batteries. In addition, the alternator is not a charger. Do not rely on the alternator to complete the work of the charger. If the battery is discharged to the point where the vehicle cannot be started, please use the charger as soon as possible to ensure that the battery is fully charged.

2)AGMS and gel cells can be tested the same way as conventional batteries.

These types of batteries have lower internal resistance than flooded batteries. Older capacitor battery testers/analyzers may not be able to accurately read these batteries. Most new battery analyzers have a special mode of AGM/gel battery. Old-fashioned load testers may not  provide conclusive results.

Using a multimeter to measure the state of charge is different from using a traditional flooded battery. After removing the surface charge, the voltage of an AGM with a 100% state of charge may be 13.0 volts. A battery filled with water may only have 12.6 volts.

3)AGM or GEL cell battery replacement is the same as flooded battery replacement. 

Although the battery installation of the two battery types may be the same, some vehicles require additional steps to tell the vehicle that the battery has been replaced.

Newer GM vehicles have a battery sensor module on the negative battery cable. Ford has a battery monitoring system (BMS). Other manufacturers have similar systems. If the battery is replaced, these systems need to be recalibrated using the scanning tool. If the system is not recalibrated, the alternator may overcharge the new battery and cause the replaced battery to quickly fail.

Some vehicles can self-learn the battery by measuring the internal resistance of the battery. But usually the scanning tool can enforce the program, so you know there will be no problems battery.

4)You can’t upgrade a customer to an AGM battery if the vehicle originally came with a flooded battery.

You can install AGM batteries into flooded battery applications. AGM batteries will provide vehicles with greater cold start power and greater heat resistance and vibration resistance. However, you never want to downgrade a vehicle equipped with AGM batteries to flooded batteries.

AGM battery can be said to be a kind of storage battery manufactured for start-stop system. Different from ordinary lead-calcium batteries, the adsorption type glass fiber board of AGM battery can ensure that the electrolyte is absorbed around the plates, so that the battery has more powerful charging and discharging capacity, faster charging and discharging speed and longer long-term deep cycle life. Effectively reduce the hidden danger of power loss and provide strong support for the start-stop system. Of course, the AGN battery without hydrogen system can also be used as an ordinary battery, but this will shorten the life of the AGM battery.

Conclusion

In summary, it is worthwhile to replace the AGM or EFB battery for vehicles with Start stop system: Auto start-stop technology is reliable and trouble-free.  Battery with Auto start stop technology provide us with a greater power reserve, longer lifespan, longer recharge and discharge cycles, and a long lasting capacity discharging.
