AGM 12V Leisure Batteries – Advantages Over Traditional Lead-Acid
1. Maintenance-Free
AGM: Sealed and maintenance-free – no need to check or top up electrolyte levels.
Lead-Acid: Often needs regular maintenance (checking water levels and electrolyte).
2. Spill-Proof & Safer
AGM: Sealed design makes it spill-proof, so it can be mounted in various orientations (except upside down).
Lead-Acid: Contains free liquid electrolyte, which can spill if tipped or damaged.
3. Lower Self-Discharge
AGM: Typically loses only 1–3% charge per month.
Lead-Acid: Can self-discharge at a rate of 5–15% per month, requiring more frequent recharging.
4. Better Vibration Resistance
AGM: The electrolyte is held in glass mats, giving excellent resistance to vibration and shock – ideal for mobile applications.
Lead-Acid: More vulnerable to vibration, which can shorten battery life.
5. Faster Charging
AGM: Can accept a higher charge current, so it recharges faster than flooded batteries.
Lead-Acid: Slower charging, which can be a drawback for off-grid or solar applications.
6. Lower Internal Resistance
AGM: Provides better performance under load and more efficient power delivery.
Lead-Acid: Higher internal resistance can reduce performance during high demand.
7. Longer Lifespan (in ideal conditions)
AGM: Often has a longer cycle life, especially when discharged moderately (e.g. 50% depth of discharge).
Lead-Acid: Shorter cycle life, especially if regularly deep-cycled.
8. No Gassing in Normal Use
AGM: Emits little to no gas under normal use, making it safer for indoor or enclosed spaces.
Lead-Acid: Can produce hydrogen gas when charging, requiring ventilation.
