What is 12V Deep Cycle AGM Battery

The term "AGM" stands for "Absorbed Glass Mat." An AGM battery is a premium type of valve-regulated lead-acid (VRLA) battery that offers significant advantages over traditional flooded lead-acid batteries. In an AGM battery, the electrolyte solution is absorbed into a specialized glass fiber mat sandwiched between the battery's positive and negative plates. This unique design completely contains the electrolyte, preventing any potential leakage or spillage. AGM batteries are classified as sealed, maintenance-free batteries because the electrolyte never needs to be refilled. Their spill-proof, leak-proof construction allows AGM batteries to be mounted in any orientation without risk. This sealed, absorbed glass mat design is what gives AGM batteries their distinctive performance benefits over standard batteries, making them ideal for renewable energy systems, vehicles, and backup power applications.

Benefits of 12V Deep Cycle AGM Battery

Higher durability
12v deep cycle agm battery were originally designed for use in military craft. The thin fiberglass mats are saturated in acid and soldered into place before being compressed between the lead plates, effectively holding the battery's electrolyte in place. As a result, 12v deep cycle agm battery have a greater resistance to vibration and impact damage than flooded batteries. The tight configuration of glass mats and lead also enables 12v deep cycle agm battery to tolerate higher temperature fluctuations and makes them more resistant to sulfation. With such durable construction, it's no wonder why you can get more starts per agm battery compared to wet cell batteries.

Improved charging
Due to the glass mat-lead-glass mat structure and compressed design of 12v deep cycle agm battery, they're able to charge up to five times faster than standard batteries. These advanced batteries also feature minimal self-discharging, meaning they can hold a full charge for extended periods of time, maintain their integrity during stretches of inactivity, and have longer lifespans than flooded batteries. This means you can spend less time charging your scissor lifts and more time working at height.

Reduced maintenance
Standard wet cell batteries require regular maintenance. If water is not added to replenish lost electrolyte in the vents, the battery will corrode and die. 12v deep cycle agm battery, on the other hand, are completely sealed and don't require any additional maintenance past plugging them in to charge. These batteries are so packed with ultra-thin fiberglass mats and lead that they naturally hold electrolyte in place, preventing water loss and reducing battery maintenance.

Increased safety
Wet cell batteries have a greater risk of spilling and exposing operators and mechanics to their hazardous internal chemicals. Since agm batteries are sealed at the factory and don't require additional maintenance, the chance of dangerous chemical spills is virtually eliminated. Agm batteries are essentially spill-proof, making them safer to use on clean jobsites and easier to transport without strict handling requirements.

How Do I Know If My Battery is Agm?

Manufacturer's labels shows such information

Battery type is usually instructed on the product labels on the body of a battery. If the label is illegible, you can also check its user manual for specifications, ask the online store or go to the store where you bought the battery.

Observe the top of your battery

AGM batteries are specifically designed with negative and positive terminals that protrude from their flat top. If you find such terminals, you can be 99.99% certain your battery is an AGM battery.

Slightly shake the battery

Highly not recommend to do this step, but since you still cannot identify your battery after going through the methods previously mentioned, this will be the ultimate choice you have to resort to.

How To Charge AGM Battery

The Charger

If you are using a VRLA battery smart charger, it is certainly the best choice. Can we use a regular charger?Well, it depends. You have to be very professional and careful, as well as follow the principle of three-stage charging.The whole process could be very complicated, so in general, it is still recommended to have a dedicated smart charger.

Three Stages Charging

The THREE STAGES CHARGING are Constant Current charge (bulk charging), Constant Voltage charge (absorption charge), and Supplemental charge (float charging).The 1st stage is constant current charging, CC for short name. We set the charger voltage to the battery (pack) cycle charge voltage, and the current to the cycle charge current. Please note that too high voltage or too high current will overcharge the battery and damage the battery. The specific voltage and current will be explained in detail in the next 2 parts. During this phase, the battery voltage rises to a constant number.

Charge Voltage

The charge voltage includes cycle charge voltage and float charge voltage, fast charge voltage. In general, the float charge voltage is used for daily floating charges, the lowest. Cycle charge voltage is used for recharging after discharged to a certain depth, it is higher. Fast charge is the voltage of rapid full charge under an emergency condition, the highest, not commonly used.

Conditions without Print

If the charge voltage is not indicated on the battery, the reasonable cycle charge voltage can be estimated according to the open-circuit voltage (OCV) when the battery is fully charged. Generally, the open-circuit voltage of the 12V battery when fully charged plus 1~1.5V is a reasonable cycle charge voltage.If you do not know the open-circuit voltage when the battery is fully charged, you can occasionally charge with 2.4V per cell blindly, but it is more difficult to judge when the battery is full. There may be overcharge, causing certain damage to the battery. Note that it's 2.4V per cell, NOT 2.4V per unit.

How to Maintain 12V Deep Cycle AGM Battery

Storing your AGM battery
When you are storing your AGM battery for longer periods, always remember to recharge. Store your battery in a place that has enough ventilation and ensure it is a cool and dry store. Avoid keeping your battery in a discharged state, as this will lead to sulfation.

Sulfation prevention
When the sulfuric acid found in the lead-acid batteries react, especially in the negative plate, it will form lead sulfate, which results in sulfation. Sulfation reduces the battery's ability to hold a charge. Keeping your AGM battery charged during and before storage will help to avoid the process of sulfation. In case sulfation occurs on your AGM battery, use a desulfation charge to reverse the sulfation. You can also use the AGM battery recommended charger to lower the impact of sulfation.

Do not overcharge the AGM battery
Maintaining the performance of your AGM battery demands correct charging. The internal structures of your AGM battery can be damaged due to overcharging. Likewise, the lifespan of your AGM battery can be reduced due to undercharging. To effectively charge your AGM battery, determine what the correct voltage should be, as written in the manufacturer's instructions. Avoid using a traditional petrol generator to charge your AGM battery.

Use the manufacturer's recommended charger
Every AGM battery has a recommended charger, as per the manufacturer. The manufacturer's charger ensures the delivery of the recommended voltage to the AGM battery without undercharging nor overcharging. When the wrong charger is used, it can cause sulfation to your AGM battery.

FAQ

Q: How do I prolong my AGM battery life?

A: Don't Run It All the Way Down.Completely discharging an AGM battery can negatively affect its lifespan. To prevent this, avoid running the battery all the way down. Aim to keep the discharge level above 50 percent, and try to never run it down below 20 percent to ensure longevity and maintain optimal performance.

Q: What maintenance is required on an AGM battery?

A: Always charge AGM batteries whenever possible. Deep or prolonged discharging leads to sulfation and shortens battery life. Be sure the positive and negative battery terminals never touch; otherwise, this could result in a fire or explosion. Protect batteries from heat and cold as much as possible.

Q: How do you maintain an AGM battery when not in use?

A: The rate of self-discharge decreases at lower ambient temperatures and will increase significantly when stored in consistently warmer ambient temperatures – up to 50% faster at 35ºC (95ºF). AGM batteries should be stored in a cool (above freezing), dry location unpackaged or in the original packaging.

Q: Can you use a regular battery maintainer on an AGM battery?

A: That being said, there's one rule that you should remember: a battery charger specifically made only for flooded cell batteries should NOT be used on VRLA batteries (including gel and AGM batteries).Manufacturing costs are higher, making the batteries more expensive. They are sensitive to overcharging and high voltages, and require full charging between uses, which can make them un-suitable for some applications where returning them to a full charge is difficult.

Q: How do I know if my AGM battery is healthy?

A: You can use data you get from the battery's voltage tests to gauge its health and all you need is a lead-test meter. it should read 12.4 volts for a healthy battery. If yours is reading 0 volts, there are chances that it has had a short circuit.

Q: Should I trickle charge an AGM battery?

A: Never use a ``trickle'' charger on an AGM battery. Even if they are very low amp voltage can rise to dangerous levels. Wet cells can tolerate overvoltage but AGM batteries cannot. For long storage periods, it is much safer to disconnect the battery.

Q: How long can an AGM battery sit unused?

A: These batteries if not used within a month must be maintained. If the voltage drops below 12.4 these batteries must be boosted up to full charge. Bottle Supplied (BS) – dry AGM batteries are shipped with the electrolyte stored in a plastic container.

Q: What is the life expectancy of an AGM battery?

A: About seven years
AGM batteries keep the battery's electrolyte in a solid, or absorbed, state that can impressively provide two to three times the lifespan of a flooded battery. AGM batteries last about seven years and are ideal for vehicles with start-stop technology.

Q: What maintenance do AGM batteries need?

A: While AGM batteries are often marketed as "maintenance-free," this doesn't mean they can be completely neglected. Basic maintenance ensures that these batteries operate optimally and have a longer service life. The key aspects of AGM battery maintenance include regular inspections, cleaning, and charging.

Q: What is the best practice for AGM batteries?

A: Avoid Over-Discharge: Regularly discharging AGM batteries below 50% of their capacity can significantly reduce their lifespan. Charge Regularly: After each use or when the state of charge drops below 50%, recharge the battery promptly. Regular charging helps preserve the capacity and performance of AGM batteries.

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

A: Different chargers have different capabilities - Although under normal conditions most 12-volt automatic battery chargers will work on an AGM battery, the battery will only charge to about 80 percent of its full capacity. Many newer battery chargers have settings specifically for AGM batteries.

Q: How do I keep my AGM battery when not in use?

A: 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.

Q: What are the common problems with AGM batteries?

A: They are sensitive to overcharging and high voltages, and require full charging between uses, which can make them un-suitable for some applications where returning them to a full charge is difficult. They require a charger specifically for AGM batteries that monitors volts, amps and ambient temperatures.

Q: How do I know if my AGM battery is good or bad?

A: A fully charged AGM battery should read between 12.8 to 13.2 volts. If the reading is below 12.4 volts, the battery may need charging or could be faulty. Readings below 12.0 volts often indicate a deeply discharged or damaged battery that may require replacement.

Q: What damages AGM batteries?

A: AGM batteries are 12 volts, like all car batteries, and can handle some higher voltage, but only up to a certain point. If a car alternator charges an AGM battery with a voltage higher than 15 volts, it can damage an AGM.

Q: Why is my AGM battery getting weak?

A: If the charge level of a fully charged AGM battery is less than 20% of a fully charged voltage level, the battery could have been damaged by sulfation, overcharging, or undercharging. It can be improved using a desulfation device or by just replacing the battery.

Q: Should I trickle charge my AGM battery?

A: ALL batteries should be trickle charged and kept cool if you want longest life. As soon as the SOC drops slightly, irreversible sulfation reactions start to occur. AGMs have lower self discharge, but it doesnt mean that you need not trickle charge.

Q: Can you jumpstart an AGM battery?

A: 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. Whether jumping flooded batteries or AGM, they answer the call day after day, year after year.

Q: Is there any maintenance on an AGM battery?

A: Standard flooded batteries, also known as wet cells, require regular topping up. This is not the case for AGM batteries since they are maintenance-free. Nevertheless, it is important to ensure that you are using your AGM battery properly, and avoid any misuse that may cause the battery's life to be shortened.

Q: How do I bring my AGM battery back to life?

A: Connect the good battery to your "bad" AGM battery in parallel (positive to positive and negative to negative). Hook up the good battery to the charger, but ensure the charger is powered off. Once connected, turn on the charger. After about an hour, see if the AGM is warm or hot to the touch.
