  Three misunderstandings about Sealed Agm Battery

  More and more batteries are packed into the trunk and under the seats of some vehicles. If the battery is not under the hood, it is probably a Sealed Agm Battery or Sealed Gel Battery. Since Sealed Agm Battery is sealed, it can avoid acid overflow in accidents. They can also be installed at strange angles.

  Battery manufacturers can reduce a few pounds of weight from the vehicle because these batteries provide a lot of energy for their size and weight. This is an important reason why they are increasingly appearing on new vehicles.

  The following are three misunderstandings about Sealed Agm Battery:

  You can use conventional battery chargers on Sealed Agm Battery or Sealed Gel batteries.

  Incorrect. These batteries like to charge slowly. Many AGM/gel battery chargers have a microprocessor that can collect information from the battery and adjust the current and voltage accordingly. Some have different settings to charge the flooded battery, Sealed Gel Battery, and Sealed AGM Battery. 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.

  The testing methods of AGM and Sealed Gel Battery are the same as traditional batteries.

  Incorrect. 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. Older load testers may not provide conclusive results.

  The replacement of AGM or Sealed Gel Battery is the same as the replacement of the flooded battery.

  True and false. 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 vehicles have battery sensor modules or 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
