How Can You Take Care Of Your Inverter Battery?

Updated by

We often hear people complaining about their inverter batteries, not longing last.

One of the main reasons for this issues is – poor maintenance that has direct impact on the performance and lifespan.

Not many people know how to properly take care of the inverter batteries.

To help everyone enjoy the optimal performance of the inverter battery, we bring this article to you.

Follow the below useful tips to extend the lifespan of your inverter battery.

Tips To Maintain And Extend The Life Of Inverter Battery

Here are some maintenance tips that ensure the proper working of your battery.

1. Check the Water Level

If you want your inverter battery to perform at its peak, ensure to maintain an adequate water level. Not maximum nor minimum, but somewhere between both. To check the same, look at the float indicators and see if the water is up to the required level. If it is not, open the indicators, and fill them with distilled water up to the defined limit. Make sure you avoid using tap water for this purpose, as it can affect battery life and performance, as well.

To inspect the health of your battery, open the vents and check the acid colour (colourless). If it is brown or black-coloured, it is a clear indication that the battery is about to die.

Note: Keep checking the water levels in the battery at least once every two months.

2. Keep Rust Away From The Battery

The next crucial step to ascertain is that the battery terminals are free from rust and corrosion. Rusting restricts the flow of current in the battery, which ultimately results in reduced battery life.

If you notice any rusting on the battery, this is how you can remove the corrosion.

This is all you need:

  • Hot Water
  • Baking Soda
  • Tooth Brush
  • Vaseline or Petroleum Jelly


  • Mix hot water and baking soda to prepare a solution.
  • Apply this solution to the corrosive areas of the battery.
  • Now, clean them using a toothbrush to remove the corrosion.
  • After cleaning, apply a bit of Vaseline or any petroleum jelly to the terminals and other parts to prevent corrosion.

3. Keep Inverter in Ventilated and Dry Area

You should always position your inverter battery in a well-ventilated and dry area. Make sure that it does not have direct exposure to sunlight or heat to ensure the efficient functioning of the battery.

We advise you to keep the battery out of the children’s reach and the source of the open fire.

4. Never Cover Your Battery On All Sides

A battery usually gets heated up when charging and also, operating. To help release the heat, it is advisable not to cover all the sides but leave some space. Make sure you clear some space behind the battery, to allow it to release the heat.

5. Place It On A Trolley Rather Than Directly On The Ground

Never place the battery directly on the ground, as the acid can spoil the flooring. Instead, have it placed on a trolley that acts as a barrier between the acid and your floor. The other benefit of using a trolley is that you can easily transport the battery when needed.

6. Avoid Tilting The Battery

Ensure the correct positioning of your battery to avoid spilling the distilled water and acid mixture on the floor. This will damage your beautiful flooring. So, never tilt your battery.

7. Change Battery When Needed

Do not neglect to change the inverter battery as and when needed. Upon usage, the batteries start losing their capacity, which, in turn, reduces the backup ability of the device.

We recommend sealed batteries and lithium batteries that offer long life. Moreover, these do not require frequent maintenance.

If you want to go for the most efficient one, prefer using tubular batteries. They offer high energy efficiency, long operational life, and fewer maintenance costs.

8. Check Inverter’s Input Power Line Condition

Always check the condition of the inverter input power line. Whenever there is a loose connection of the mainline power cord, the functioning of the battery gets effected.

Voltage fluctuations, high/low input voltage or a blown away fuse will impact the battery performance.

9. Do Not Overload The Battery

It is never a good idea to overload the battery. Whenever there is a power failure, the battery gets overloaded, reducing the backup period. It becomes imperative to disconnect those devices that tend to consume more power and drain the battery energy. Disconnecting the devices helps in significantly increasing the backup of the battery by cutting off the extra load.

10. Use Your Battery Regularly

It is essential to use your batter regularly after the installation. In any case, there is no power cut in your locality, it is better to discharge the battery completely and then recharge it again to ensure its efficient functioning and performance.

11. Check Vents

Keeping the vents around the battery-free from dust and clogging is very important. Block vents tend to accumulate hydrogen gas inside the battery, which will eventually lead to the bursting of the device.

12. Keep the Battery Surface Spotless

Always keep the surface of the battery-free from dust and dirt. Whenever you notice deposits of dirt, clean it immediately using a cloth. Ensure the clean surface of the battery to ensure relentless functioning.

13. Damaged Wire Affects Performance

This is the most important thing to check if you want to maintain the long life of your inverter battery. Inspect the wires to check for the signs of a break, crimps, or insulation melt on them. A damaged wire can pose a threat to short circuits in the house.

14. Check Battery Only When Fully Charged

You can conduct a maintenance check on your inverter battery, only when it is fully charged. To ensure that, your battery requires charging for about 10-15 hours using a suitable inverter or an external device.

You can carry with your battery health check regime after it fully recharges. But before that, you need to disconnect the inverter from the socket and then remove it from the front panel.

15. Use Energy-Saving Appliances And Gadgets

If you want to lower the electricity consumption and save on your inverter battery, using energy-saving devices can be a suitable option. Let us say you are using ordinary bulbs at home. Try replacing them with LED bulbs as it efficiently minimizes power consumption up to 75% than incandescent bulbs. Similarly, you can use energy-efficient bulbs and fans to save energy.
