Do AGM Batteries Need a Special Charger? – Battery Hunters

A specific charger is not required for AGM batteries, but a special charging mechanism is required. It will reap the benefits of a high-quality “smart” charging station. A typical constant voltage charger that puts out electricity at roughly 12.7v can be found at your local auto parts store. It’s finished.

Partial charging is not possible with AGM batteries. The charge must be finished. There are some smart chargers for these batteries that perform everything you need them to accomplish. Everything would be very quick and simple if you purchase a smart charger for your battery. You should understand the technology of a charger before acquiring one. The entire technique will be simple enough if you execute it correctly. The charging technique for these batteries has a set range. It denotes that the charging system is not a standard method. It has some specific requirements, such as a temperature range. Anyone who wishes to charge their battery should learn about the proper temperature range.

They need to be recharged (they can’t tell when the battery is fully charged). A smart charger that is compatible with AGM batteries is required to keep your battery in peak condition for many years.

Because of the numerous advantages that AGM batteries provide, they have grown much more popular in recent years. They are appropriate for vehicles with 

• start/stop technology, 
• have bigger power reserves
• can be mounted in any position,
• are maintenance-free, and much more. 

Special production process distinguishes absorbent Glass Mat batteries from normal lead-acid models: liquid electrolyte is absorbed by microporous material (fibreglass). The battery can be used in:

• Cars
• Trucks
• Boats
• Motorcycles 
• Scooters
• specific equipment
• backup or emergency power sources.

The abbreviation stands for “absorbed glass mat,” and it’s one of the many enhancements to Planté’s original train light battery. Glass matting will compress like a sponge, cushioning the ultra-thin lead plates. As a result, producers can pack more glass mats and lead into each battery. More lead equates to more strength. Furthermore, the battery’s insides are packed firmly due to the squish factor. 

Do AGM batteries require Maintenance?

No, AGM batteries do not require maintenance and this is a mistaken statement. To ensure steady and long-term functioning, you must first choose the best charger and follow some guidelines when using it.

For AGM batteries, you can use your usual battery charger?

No, it is just a misconception, these batteries prefer to be charged slowly and at a low current. Microprocessors collect data from the battery in many chargers that alter the current and voltage accordingly. Some chargers have various charging settings for flooded, gel, and AGM batteries. Overcharging these batteries can result in their death. Alternators are also not chargers. Don’t expect an alternator to perform the same functions as a ­charger. If a battery is completely depleted and unable to start the car, use a charger as soon as possible to ensure that the battery is fully charged. 

Some useful tips 

• Charge batteries with an absorbent glass mat under special conditions and with appropriate chargers. Your vehicle must not be started from another vehicle under any circumstances.
• Unscrew the plugs and make sure the glass mat isn’t dry before charging. Otherwise, distilled water should be used to moisten it. 
• The simultaneous fall in charge voltage and increase in charge current is a classic sign that thermal dispersion is beginning. Stop charging and take a break for gradual diffusion in this scenario. Allow the charged and uncharged electrolytes to mix in the glass mat at varied current resistances.

✔In addition to standard charge control techniques,
✔Allow for a maximum voltage of 14.4 volts and a maximum charging current of 1/10 of the normal battery capacity.
✔keep an eye on the temperature.

• Each type of battery has its own set of recommended chargers with enough voltage to charge it. Unfortunately, utilizing the improper charger can lead to a battery short circuit.
• Because AGM batteries are made of lead acid, you should avoid charging them when the weather is too cold or too hot. To extend the life of the batteries, charge them while the temperature is between 0° and 40° Celsius.
• Before leaving, make sure the battery is completely charged. A fully charged battery should have a voltage of 13.00 volts or higher. Ideally, the final charge should be performed using an AGM-optimized charging profile.
