What happens if you charge an AGM battery with normal charger?

You can use your regular battery charger on AGM or gel cell batteries. False. These batteries like to be charged slow and low. Many AGM/gel cell battery chargers have microprocessors that collect information from the battery and adjust the current and voltage accordingly.

Does an AGM battery need a special alternator?

These batteries like to be charged slow and low due to differences in internal resistance. Many AGM battery chargers have microprocessors that collect information from the battery and adjust the current and voltage accordingly. … Don’t rely on an alternator to do the work of a charger.

How long does an AGM car battery last?

We can generally say an AGM battery can last two to three times as long as a flooded battery. In the commuter car example we referenced, if a flooded battery lasts three to five years, an AGM battery could last six to ten years or longer.

What is the advantage of an AGM battery?

AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead-acid type. It stands up well to low temperatures and has a low self-discharge. The leading advantages are a charge that is up to five times faster than the flooded version, and the ability to deep cycle.

Are AGM batteries better in cold weather?

The benefits of AGM batteries during winter

AGM batteries have a higher cold cranking amps (CCAs) rating than your average battery. An AGM battery in your RV or boat will crank faster in colder temperatures than a standard battery. Because AGM batteries have a low self-discharge, they stand up to cold temperatures.

How do I know if my BMW battery is AGM?

On to the type of battery which is very simple to determine with factory original BMW batteries, a white battery is a standard lead acid battery, and a black battery indicates an AGM (Boron-Silicate absorbed glass mat).

Why are AGM batteries so expensive?
