An AGM battery is a lead-acid battery that uses a glass mat separator and sulfuric acid to absorb and immobilize the electrolyte. This sealed design allows AGM batteries to be used without leaking or spilling in any orientation. AGM batteries are often used in vehicles and boats' starting, lighting, and ignition (SLI) applications.
AGM batteries are also often used in portable applications such as power tools, medical equipment, and uninterruptible power supplies. Because of their high discharge rates and fast recharging capabilities, AGM batteries are ideal for use in situations where short bursts of energy are needed. AGM batteries offer several advantages over other lead-acid battery designs, including:
• Longer life span
- AGM batteries can last up to twice as long as standard lead-acid batteries.
- This extended lifespan can be attributed to the AGM battery’s design, which allows for superior cycle life and reduced sulfation.
- AGM batteries are also less susceptible to damage from vibration and shock than standard lead-acid batteries.
• High discharge rates
- AGM batteries can deliver high currents without damaging the battery cells.
- This makes AGM batteries ideal for use in applications where a high level of power is needed in a short amount of time.
- AGM batteries can also be quickly recharged, allowing them to be used multiple times in a day.
• Low maintenance
- AGM batteries require very little maintenance, making them an ideal choice for applications where reliability is key.
- AGM batteries also do not need to be regularly watered, which can help save time and money.
Disadavantages of AGM batteries
• Higher cost
- AGM batteries are more expensive than standard lead-acid or gel cell batteries.
- Despite the higher initial price, however, many customers find that the longer lifespan and lower maintenance of an AGM battery outweigh its increased cost over time.
• Special charging requirements
- Unlike wet cell batteries, AGM batteries require a special charging technique known as "bulk" or "absorption" charge.
- Batteries should always be charged at a slow rate if they have been discharged or are low on power.
- If you try to recharge an AGM battery using the incorrect technique quickly, you may damage the battery cells.
AGM batteries are a favorite choice for many industrial and commercial applications despite these minor disadvantages. With their high discharge rates, long lifespan, and low maintenance requirements, AGM batteries provide an excellent combination of performance and value. For applications where reliability is key, AGM batteries are hard to beat.
Another thing about AGM batteries is that they can be mounted in any position due to the Absorbed Glass Mat separators. This isn't as much of a concern in automotive applications where the battery is typically mounted in a fixed location. Still, it's important for portable applications and applications where vibration might be an issue. It also means that AGM batteries can be used in "wet" or "flooded" applications, which is a big plus for people looking for a versatile and durable battery.
AGM batteries have quickly become a favorite choice for many industrial and commercial applications. With their high discharge rates, long lifespan, and low maintenance requirements, AGM batteries provide an excellent combination of performance and value.
