What is AGM Battery for Powered Access

AGM means absorbed glass mat, and it means the battery acid inside is absorbed into fiberglass mats instead of sitting as a free-flowing liquid.The fiberglass mats spread more of the electrolyte in contact with the ultra-thin lead plates — all while cushioning the battery against knocks, bumps and vibrations. Because of the absorbent glass mats, battery makers can literally squeeze in more lead plates. More lead in the battery means more available power.

Benefits of AGM Battery for Powered Access

AGM Battery for Powered Access Components

01.

Lead Plates

AGM batteries contain lead plates, which serve as the positive and negative electrodes. These plates are typically made of a lead-calcium alloy to improve their durability and reduce water loss during charging.

02.

Absorbent Glass Mat (AGM)

AGM batteries feature a fiberglass mat separator that is saturated with electrolyte (usually sulfuric acid). This mat is placed between the lead plates and acts as a sponge to hold the electrolyte in place, preventing spillage and allowing for a maintenance-free design.

03.

Electrolyte

The electrolyte in AGM batteries is typically sulfuric acid (H2SO4), which is absorbed into the fiberglass mat. This electrolyte facilitates the electrochemical reactions that occur during battery discharge and recharge cycles.

04.

Battery Case

The battery case houses all the internal components and provides physical protection and containment for the electrolyte and other materials.

AGM Battery Vs Regular Battery(Flooded)

These batteries have lead plates submerged in a liquid electrolyte. The liquid freely moves within the battery case, and the level can be checked and topped off with distilled water if needed. This is why these batteries are sometimes referred to as “wet cell” batteries.

Construction

Flooded lead-acid batteries require regular maintenance, such as checking the electrolyte levels and adding distilled water when necessary. They also need to be kept upright to prevent spills and must be vented to allow gases produced during charging to escape safely.

Maintenance

While they are cost-effective and reliable, flooded batteries are more prone to sulfation (crystallization on the lead plates), which can shorten their lifespan if not properly maintained. They are also less tolerant of deep discharges and can be damaged if not recharged promptly after use.

Performance

How to Choose AGM Battery for Powered Access

Motor Specifications
Voltage: Ensure the AGM battery voltage matches the voltage requirements of your motor. Common voltages for electric motors include 12V, 24V, 36V, and 48V. Using a battery with an incompatible voltage can damage the motor or lead to inefficient operation.Continuous Current Draw (CCD): The CCD refers to the constant current the motor draws during operation. Choose an AGM battery with a capacity that exceeds the motor's CCD to ensure sufficient power delivery and prevent premature battery discharge. Battery capacity is typically measured in amp-hours (Ah).

Battery Capacity (Ah)
The battery's Ah rating indicates the total amount of current it can deliver over a specific time period. A higher Ah rating translates to longer runtime between charges. Here's a simplified approach to estimate the required battery capacity:Runtime (hours) = Battery Capacity (Ah) / Motor CCD (amps)This is a basic formula, and factors like motor efficiency and operating temperature can influence runtime. Consider using a safety factor of 1.2 to 1.5 times the calculated runtime to account for these variables and ensure adequate power reserves.

Cold Cranking Amps (CCA)
While cold cranking amps (CCA) may not be as crucial for electric motors as they are for starting gasoline engines, they can still be pertinent for applications involving high initial loads, such as winches or mobility scooters used on inclines. A higher CCA rating indicates better performance in cold temperatures, making it an important consideration for ensuring reliable operation in challenging environmental conditions.

Discharge Rate
Deep-cycle AGM (Absorbent Glass Mat) batteries are specifically engineered for applications that involve frequent discharges and recharges, such as in renewable energy systems, RVs, boats, and off-grid solar power systems. These batteries are designed to provide sustained power over extended periods, making them ideal for deep-discharge cycles.

How AGM Batteries Work

Absorption

During charging, the glass mat absorbs and retains the electrolyte, preventing spillage and making AGM batteries maintenance-free. This also means they can be installed in various positions, including on their side, without the risk of leakage.

Recombination

AGM batteries employ a unique recombination process. As gas is produced during charging and discharging-a process that's normal conditions for all batteries – it is recombined within the battery rather than being released into the atmosphere. This minimizes the need for topping up the electrolyte.

Low Internal Resistance

AGM batteries have lower internal resistance compared to flooded lead-acid batteries. This results in quicker charging and discharging, making them ideal for high-demand applications.

How to charge an AGM battery

01/

Plug in your AGM-compatible battery charger. Follow any other instructions for your specific charger.Connect a backup power supply to the onboard diagnostics OBD-II Port.

02/

Disconnect the car's negative terminal and wrap it with a glove, rag or anything to prevent it from touching any metal. The negative cable is usually black, but you can also look for a minus (-) symbol on the cable as well.

03/

IMPORTANT: Select AGM or Absorbed for the battery type on your charger. A smart charger may detect the voltage and battery type when you connect it, but don't leave it to chance. Select 12 volts to match the voltage of your AGM battery.

04/

Connect the charger to your car battery posts. Again, check the indicator lights and make sure they're set to AGM or Absorbed.
Start the charger and wait two to eight hours to fully charge your AGM battery.

05/

Disconnect the charger from the battery when it's done. Your charger's indicator light will signal when it's done charging the battery.

06/

Again, avoid letting the charger's clamps touch the battery's loose negative clamp.Reconnect the car's negative terminal to the battery. Disconnect the backup battery. Now you're ready to hit the road with a fresh start.

How to Maintain AGM Battery for Powered Access

AGM Batteries Should Never Be Partially Charged
In order to preserve their capacity, all absorbent glass mat batteries must be fully charged to 100 percent. When AGM batteries are only partially charged, they lose their ability to charge to their maximum capacity over time. If you only charge your AGM battery to 60% all the time, it may eventually fail to charge beyond that point. As a result, the battery's lifespan is reduced.

How to Store Your AGM Battery
Make sure your battery is stored in a cool, dry location with plenty of ventilation. Sulfation will occur if your battery is left drained for long periods of time. Always ensure to recharge your AGM battery when keeping it for prolonged periods of time.

They Should Be Charged at the Correct Temperature
To extend the life of the batteries, charge them while the temperature is between 0° and 40° celsius. If you charge lead-acid batteries in temperatures between 0° and above 40°, they can be damaged. Because AGM batteries are made of lead acid, you should prevent charging them in extreme temperatures.

Only Use the Chargers Advised by the Manufacturer
A huge AGM battery will certainly demand a large charger capable of matching its capacity. In most cases, the capacity of the AGM batteries and chargers is shown in amperes. Simply checking the suggested amps on the battery will tell you which charger is best for your AGM battery.

Preventing Sulfation
The ability of the battery to keep a charge is affected by sulfation. When a battery is not given a complete charge, sulfation develops and persists on the battery plates. It can be avoided if you keep your AGM battery charged during and before storage. In addition, to reduce the impact of sulfation, utilize the AGM battery's recommended charger.

The AGM Battery Should Not Be Overcharged
Determine the correct voltage as specified in the manufacturer's instructions to charge your AGM battery effectively. To charge your AGM battery, avoid using a standard fuel generator. Overcharging might destroy the structural components of your AGM battery. Similarly, undercharging might affect the longevity of an AGM battery.
