What is an agm battery

Instead of the free-flowing liquid inside of a regular car battery, the AGM carries its charge in soaked sponges coating the lead plates. The glass mats' complete coverage makes it easier to summon more power from an AGM battery — and make it easier to recharge.

What is the main disadvantage of an AGM battery?

The main disadvantage of an AGM battery is the up-front cost, when compared to a traditional flooded lead-acid battery.

Can I charge an AGM battery with a regular charger?

Can You Charge an AGM Battery with a Regular Charger? One important thing to keep in mind is that you can't charge an AGM battery using a standard battery charger. This is because AGM batteries have different charging requirements than standard flooded batteries.

How do I know if I have an AGM battery?

Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out. On the other hand, the liquid acid batteries have a removable top which is not the case with AGM batteries as they are properly sealed.

Can I jump start an AGM battery?

Your One-Stop Solution for AGM Service As mentioned above, jump starting AGM batteries is very straightforward. That said, our Booster PAC and Jump-N-Carry traditional jump starters use AGM batteries in them and are legendary for their power and durability.

Can I trickle charge a AGM battery?

Many GEL, AGM and Calcium's are better than regular lead-acid batteries but even so you should charge them back up regularly, or better still use a trickle charger (or solar panel) to keep them in top condition and extend their life.

Can I replace a lead acid battery with AGM?

Yes for the most part an AGM is a drop in replacement for your standard Lead Acid Battery. The charging voltages are almost identical.

Is it worth buying an AGM battery?

Many AGM batteries will last two to three times as long as their flooded counterparts, so from that perspective it seems to at least make sense. When you add in the safety benefits of an AGM battery on top of the performance benefits, AGM batteries make even more sense.

What kind of charger do I need for AGM batteries?

Traditional battery chargers are not suitable for AGM batteries because they will overcharge them (they can't detect when the battery is fully charged). To keep your AGM battery in top condition for multiple years, you need a smart charger, which is compatible with AGM batteries.

Why do AGM batteries need a special charger?

AGM batteries do require a "special charger" in that the charger must not charge in excess of 15.3 volts. Many less expensive chargers can and will over charge a battery delivering in excess of 17 volts. AGM batteries use a self closing valve to deal with expansion.

How do you charge an AGM battery?

The best way to charge an AGM battery is with a charger designed for that specific purpose. When charging, remember that AGM batteries must not be charged over 14.8 volts in most cases. The manufacturer of your particular battery probably has a specification and guide sheet to set some specific rules and guidelines.

How do you tell if my car battery is AGM or standard?

If the label is still in good condition, see if it has “AGM” or “Absorbed Glass Mat” written on it. The label could also say “sealed” or “maintenance-free” to indicate that it's an AGM. However, if the battery label displays “flooded” “Wet” or has removable caps, it's probably a flooded lead-acid (FLA) battery.

How long does AGM 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.

Why do some cars require AGM batteries?

If the vehicle is equipped with a large number of non-standard electrical devices, which have an increased power consumption, e.g. a sophisticated sound system, the AGM battery provides the vehicle with the necessary power, which a conventional wet battery cannot provide.

Do new AGM batteries need to be charged?

Newly activated AGM batteries require an initial charge. After the “stand” period described in step 6, charge the battery to bring it to a full state-of-charge. The battery charger used for initial charging should be able to charge at 12.8+ volts for an AGM battery.

Can you ruin a AGM battery?

Severely discharging and leaving the battery discharged can cause harm and shorten life in AGM batteries.

What happens if you charge an AGM battery on standard?

Using the gel setting to charge an AGM battery will not fully charge and over time will actually damage your AGM battery. Lower is better - A low amp charger (1 to 10 amps) is always the best choice for charging any lead acid battery.

What are the pros and cons of AGM batteries?

Are AGM batteries better in cold weather?

AGM batteries perform much better in low temperature environments than flooded lead acid batteries do. For starters, AGM batteries typically have higher CCA ratings than a flooded lead acid battery. They also have a slower discharge rate than lead acid options, meaning they do a better job of holding a charge.

Can you add distilled water to AGM battery?

Third, never try to add water to any AGM battery. Not only will this maneuver not rejuvenate an AGM battery, it will ruin the unit by exposing its innards to unwanted outside oxygen. Chemically, outside air poisons the contents of an AGM battery.
