AGM stands for Absorbent Glass Mat, a technology used in modern lead-acid batteries. Inside the battery, a fine fiberglass mat absorbs the acid, preventing it from spilling and making the battery safer and more durable.
AGM batteries are an advanced type of lead-acid battery that offer many advantages over traditional flooded batteries. They are maintenance-free and designed to reduce water loss while withstanding vibrations. This makes them ideal for vehicles with high power needs or those used on rough terrains, such as ATVs, motorcycles, UTVs, and snowmobiles.
AGM vs Traditional Battery
Traditional batteries, often called flooded batteries, contain freely moving acid. In contrast, AGM batteries trap the acid in the glass mat, greatly reducing the risk of leaks. They can be installed at any angle, offer better vibration resistance, and require no regular maintenance.
| Feature | Traditional Battery | AGM Battery |
|---|---|---|
| Acid State | Free-moving acid | Absorbed in glass mat |
| Leak Risk | Higher | Very low |
| Installation Angle | Must be upright | Any angle |
| Vibration Resistance | Low | High |
| Maintenance | Regular checks needed | Maintenance-free |
| Cost | Lower | Higher |
| Lifespan | Shorter | Longer |
Yuasa AGM Battery Models
Yuasa produces various AGM series including YTZ, GYZ, YTX, and YIX, designed to meet different power requirements. Detailed cutaway views are available on Yuasa’s website for a deeper look into their internal construction.
Benefits of AGM Batteries
- Lower power loss: Holds charge longer
- Minimal leakage risk: Safer for users and vehicles
- High vibration resistance: Great for rough and off-road use
- Flexible installation: Can be mounted in various positions
- Better performance in cold climates: Reliable in winter conditions
When to Choose Traditional Batteries?
If you drive daily on smooth roads and have budget constraints, traditional batteries might be a more affordable choice. However, they require regular maintenance and carry a higher risk of acid leakage.
Important: AGM batteries are not a direct drop-in replacement for traditional batteries as their charging requirements differ. Using the wrong charging system can damage your vehicle’s electrical system.
Typical Uses for AGM Batteries
- Off-road vehicles (ATVs)
- Snowmobiles
- Motorcycles
- Utility Task Vehicles (UTVs)
- High-power vehicles requiring durability and reliability
