Nothing is more frustrating than a power cut that leaves you in the dark, only to find your inverter battery has given up. While these devices are our saviours, they can only perform well if they are looked after properly. Without the right care, an inverter battery’s working life can shorten dramatically, leaving you to wait for the power to come back on. By adopting a few straightforward habits, you can ensure your battery remains in top condition, providing a reliable power supply for fans, lights, and television sets for hours on end.


Top Tips for Inverter Battery Care


Maintain Proper Water Levels


For lead-acid batteries, commonly used in inverters, maintaining the correct water level is crucial. Always use distilled water, as tap water can damage the battery’s plates. Check the water level monthly, ensuring it stays below the maximum mark to avoid overflow. Low water levels expose plates to air, causing irreversible damage, so regular checks are a must for long-lasting performance.

Keep the Battery Clean and Dry


Dust, dirt, and rust on battery terminals can affect charging efficiency. Clean the terminals regularly and apply petroleum jelly to prevent corrosion. Place the battery in a well-ventilated, dry area, as excessive heat or moisture can reduce its lifespan.


Avoid Overloading the Inverter


Overloading your inverter with heavy appliances like air conditioners or refrigerators can strain the battery, causing frequent discharges. For a 150AH battery, keep the load below 80-85% to maintain efficiency. Ensure the inverter is fully charged when power returns, as partial charging can degrade the battery over time. Good ventilation around the inverter also prevents overheating, preserving its health.

Choose the Right Battery and Service Support


Select an inverter battery based on your household needs. For homes with multiple appliances, a tubular battery is ideal since it lasts longer. Always go for reputed brands and check the warranty and service options before buying. Regular servicing ensures better performance and durability.


Your inverter battery doesn’t have to give up during crucial times. By maintaining water levels, ensuring cleanliness, preventing overload, and choosing the right battery, you can enjoy hours of uninterrupted power backup. A little care today will reward you with longer life and reliable performance tomorrow.
