Battery Maintenance Tips to Double Your Battery Life

Most inverter batteries that fail early were not defective — they were neglected. A few minutes of attention every month is the difference between three years of service and seven.

Check the water level every 45 to 60 days

Use only distilled water and fill to the upper mark, never above it. Tap water carries minerals that permanently damage the plates. In Siliguri's humid summers, check more often — evaporation speeds up considerably.

Keep terminals clean and tight

White or blue powdery buildup on the terminals raises resistance and starves the battery of charge. Disconnect, scrub gently with a stiff brush and a mild baking soda solution, dry fully, then reconnect and apply a thin coat of petroleum jelly.

Ventilate and position properly

• Keep the battery in an open, airy spot — never inside a closed cabinet
• Stand it on a trolley or wooden base, not directly on a cold floor
• Keep it out of direct sunlight and away from heat sources

Discharge it occasionally

If your area has few power cuts, run the battery down on inverter mode once a month and let it recharge fully. Batteries that sit permanently on float charge lose capacity over time.

Know the warning signs

Backup time dropping suddenly, a swollen casing, a burning smell or unusually long recharge times all mean it is time for a test. Call us and we will check the battery at your doorstep before it strands you.
