Tubular lead-acid batteries are a popular choice for inverters due to their durability and deep-cycle capabilities. However, proper maintenance is crucial to ensure optimal performance and extend their lifespan. This article provides key tips for maintaining your tubular lead-acid inverter battery:

1. Water Level Maintenance

• Regular Checks: Regularly check the water levels in each cell. The frequency depends on usage and environmental conditions, but generally, check at least once every 2-3 months. More frequent checks are recommended in hot climates or with heavy usage.
• Topping Up: If the water level is low, carefully top up with distilled water only. Never use tap water, as it contains impurities that can damage the battery.
• Avoid Overfilling: Ensure the water level remains within the recommended range. Overfilling can lead to acid spillage during charging.

2. Terminal Care

• Corrosion Prevention: Corrosion on battery terminals can hinder performance and lead to poor connections.
• Cleaning: Regularly clean terminals with a baking soda and water solution. Apply petroleum jelly or a terminal protector afterward to prevent future corrosion.

3. Prevent Overcharging

• Charger Compatibility: Use a compatible charger with an automatic shutoff feature to prevent overcharging, which can significantly damage the battery.
• Inverter Settings: Ensure your inverter is set up to properly regulate charging.

4. Avoid Deep Discharge

• Regular Use: Try to use the battery at least once a month to prevent deep discharge, which can significantly reduce its lifespan.
• State of Charge Monitoring: Keep an eye on the battery’s state of charge to avoid deep discharge.

5. Environmental Considerations

• Temperature Control: Avoid storing the battery in direct sunlight or near heat sources. High temperatures can accelerate battery degradation.
• Dry Environment: Keep the battery area dry to prevent corrosion and short circuits.

6. Professional Maintenance

• Regular Checkups: Consider having a qualified technician perform regular maintenance checks on your battery, especially if you’re unsure about any aspect of battery care.

7. Battery Replacement

• Lifespan: Tubular batteries typically have a lifespan of 5-7 years with proper maintenance.
• Replacement: Consider replacing older batteries to avoid unexpected failures.

By following these maintenance tips, you can significantly extend the lifespan of your tubular lead-acid inverter battery and ensure reliable power during outages. Remember to refer to your battery’s warranty and maintenance guidelines for specific recommendations.
