Maintenance is essential for prolonging the service life of AGM (Absorbent Glass Mat) batteries. Although Redway Power offers maintenance-free AGM batteries, improper use can shorten their lifespan. In this guide, we will categorize AGM battery maintenance into three crucial aspects: storage, sulfation, and charging.
AGM batteries are typically maintenance-free but misuse can lead to issues like sulfation:
1. AGM Battery Storage
Proper storage is vital to maintain AGM batteries:- Temperature Control: Store AGM batteries in cool environments to prevent shortened service life caused by high temperatures.
- Ventilation: Ensure batteries are stored in well-ventilated areas, never in sealed containers, to prevent gas accumulation during charging and discharging cycles.
- Regular Recharging: If storing AGM batteries for later use, recharge them fully at least once every 4 to 6 months.
2. Addressing Sulfation
AGM batteries are typically maintenance-free but misuse can lead to issues like sulfation:- Sulfation Overview: Sulfation occurs when sulfuric acid in the battery reacts, forming lead sulfate on the negative plates and terminals, reducing acid surface area and hindering charge retention.
- Prevention: Charge AGM batteries before storing them to mitigate sulfation risks.
- Reversing Sulfation: While some chargers claim to reverse sulfation, they have limited effectiveness and might not fully restore the battery. Replacement may be a more practical option.
3. Proper AGM Battery Charging
Correct charging procedures and appropriate AGM battery chargers are essential for optimal battery performance:- Avoid Overcharging: Overcharging damages the internal structure of AGM batteries, causing inflation and excessive gas release. It may render the battery unusable.
- Prevent Undercharging: Regular undercharging may lead to a reduced ability to reach a full 100% charge, resulting in a shorter service life. Ensure consistent full charging to maintain battery health.
