Maintenance-free lead-acid batteries, also known as sealed lead-acid (SLA) or valve-regulated lead-acid (VRLA) batteries, are designed to require minimal maintenance compared to traditional flooded lead-acid batteries. However, they still require some care to ensure optimal performance and longevity. Here are a few considerations.
- Regular Charging: Keep the battery charged. Regularly check and ensure the battery is charged to avoid deep discharges, which can reduce battery life.
- Clean Connections: Inspect and clean the battery terminals and connections to prevent corrosion and ensure a good electrical connection.
- Proper Storage: Store the battery in a cool, dry place. Extreme temperatures, especially heat, can reduce battery life.
- Monitoring: Occasionally check the battery voltage and overall condition. Some VRLA batteries have indicators to show the state of charge.
- Avoid Overcharging: Use a proper charger designed for VRLA batteries to prevent overcharging, which can cause the battery to overheat and fail.
While these tasks are minimal compared to traditional batteries, following them helps maintain the performance and lifespan of maintenance-free lead-acid batteries.
