- Filtered drinking water
Only distilled battery-grade water should be used because impurities can damage battery plates and reduce battery efficiency.
Keep Battery Terminals Clean
Battery terminals gradually accumulate:
- Corrosion
- Dust
- Oxidation deposits
These deposits increase electrical resistance and reduce charging efficiency.
Cleaning Procedure
- Turn off the inverter.
- Disconnect power supply.
- Inspect terminals.
- Clean corrosion gently.
- Tighten loose connections.
Benefits of Clean Terminals
- Better charging performance
- Lower power loss
- Improved battery efficiency
- Longer battery life
I advise homeowners in Lucknow to inspect terminals at least once every two months.
Avoid Deep Battery Discharge
Deep discharge is one of the most common reasons batteries fail early.
What Is Deep Discharge?
Deep discharge occurs when the battery drains almost completely before recharging.
Repeated deep discharges can:
- Damage battery plates
- Reduce battery capacity
- Shorten battery lifespan
Best Practice
Recharge the battery as soon as electricity returns.
Modern inverters automatically recharge batteries, but frequent complete discharge cycles should still be avoided.
Try not to overload the inverter with unnecessary appliances during power outages.
Prevent Overloading of the Inverter
Many households connect more appliances than the inverter is designed to support.
Common examples include:
- Air conditioners
- Water pumps
- Electric irons
- Room heaters
- Heavy-duty motors
Overloading can cause:
- Excessive battery drain
- Increased inverter stress
- Reduced backup duration
- Battery overheating
Recommended Approach
Use inverter backup primarily for:
- Fans
