Inverter: Nowadays it has become common in the house to have an inverter. It is most useful when there is frequent power cuts during summer and rainy season. But have you ever thought that you have got the inverter installed, but the correct maintenance of his battery is equally important? Most people do not know that water is poured into the battery of the inverter. Water is also not an ordinary water, but distilled water. But many times people ignore it. Due to this negligence, the battery gets spoiled quickly and water has to be spent again and again. Learn here why water is poured in the battery of the inverter, when to put and what precautions should be taken.

How does the battery of the inverter work?

The inverter battery consists of lead-acid cells. This battery uses electrolyte, a kind of liquid acid and distilled water in the process of charging and discharging.

When the battery is used or charged, the water present in it slowly starts to evaporate. If water is not poured from time to time, the electrolyte levels decrease and the functionality of the battery is affected.

Why is it necessary to pour water in the battery?

To maintain electrolyte levels, to work properly of the battery, it is necessary to have a certain level of electrolyte. This level remains balanced with distilled water.

It is also necessary to increase the battery life. If you pour water on time, the battery will continue for many years without any problem. To prevent overheating and preventing spoilage, dry battery is more hot, causing water or burst. To maintain charging efficiency, the right water level keeps the battery fully charged and also gives good backup.

Can tap water be added?

As mentioned above, only distilled water should be poured in the inverter battery. Tap water contains minerals, salt, iron etc. which can damage the internal plates of the battery. This causes the battery spoil quickly and also reduces backup.

When should water be poured?

Check the battery once a month. If the water level is low, add the same water that the plates are completely submerged. Do not add excess water, otherwise the acid can be leaked from the battery.
