The invention of electricity was and still is considered one of the best inventions in the history of mankind. But the invention of the inverter made things better than ever. It allows the power supply to your house to continue when the main power supply from the powerhouse is off or there is a hindrance. The number of appliances that can run on the inverter depends on its wattage and power. Did you know that they use distilled water on the top of inverter batteries? If you didn’t, there is no to worry. This article will teach you everything about inverter batteries, from how to make distilled water for inverter battery to what is distilled water for inverter battery price in market.

What is Distilled Water for Batteries?

The purest form of water is known as distilled water. It is free from additional minerals that are usually found in regular tap water. Lead-acid batteries are topped with distilled water, particularly inverter batteries. Tap water has several impurities and a high concentration of ions which can obstruct the chemical reaction taking place in the battery. Distilled water is used because it does not obstruct the functioning of the battery and helps it to work seamlessly. You can prepare the distilled water yourself or get it from the market. After this, let’s finally find out how to make distilled water for inverter battery.

How to Make Distilled Water for Inverter Battery?

It may seem a big task, but it is not so. I am sure everyone has a pot and stove at home. All you need is water, a pot, ice cubes, and a stove. You can easily make distilled water by these two methods-

1. Fuel Distillation

As the name suggests, in this process you have to use fuel to make distilled water. 8-9 cups of water will make 1 cup of distilled water. Considering this ratio, you can calculate the quantity of water you need to make the required amount of distilled water. For this method, you will need a  large pot, a small pot, a large burner, and a lot of ice cubes.

Step 1: Take the accurate and adequate amounts of water in a pot and place it on the stovetop. Place a small pot inside the large pot and let it float on the water. This technique will help in the circulation of water vapor. Also, ensure there is enough space between the two pots for adequate airflow.

Step 2: Keep the flame between medium and medium-high. To maintain the heat range, you can turn on the steady simmer alternatively, between 180° Fahrenheit and 200° Fahrenheit (82°-93° Celsius).

Step 3: Place the lid upside down after a few minutes. Placing the lid this way will help in the better and easier accumulation of condensed water. Next, put lots of ice cubes in the lid (covering the surface of the lid) and let them melt. It is done to trigger the condensation process.

Step 4: Once the 1st batch of ice cubes melts, add another batch. This needs to be done twice in an hour without turning off the heat. If required, you can repeat the supply 4 to 5 times. But be careful while you dump the melted ice.

Step 5: After 2 or 3 hours of the condensation process, you will notice the water dripping down into the small pot. This is the water that you call distilled water. You can use it for your inverter battery, but such a little amount may not be sufficient. Therefore, calculate the ratio and try to do this process again.

2. Solar Distillation

Equipment and things are the same in this method too, but instead of a burner, you will use solar heat. Take a pot with a large diameter and a glass lid.

Step 1: Try the process on a bright sunny day between 12 noon and 4:00 pm. The large pot should be vertically long enough for easy circulation of hot air. You can use jars in place of pots.

Step 2: Put water in a large pot and place a small pot inside it. The pots must be made of glass or metal to speed up the solar heating process. Remember, the size of the pots or jars should be enough to maintain the airflow between their walls.

Step 3: Is it not easy to learn how to make distilled water for inverter battery? Place the pots or jars on a solar reflector. It will increase the heat level and speed up the process. Cover the jar with its cover or pot with the lid upside down.

Step 4: Keep adding the water if the reaming water gets evaporated. The process may take 5-6 hours or sometimes even more as everything depends on the intensity of the sunlight. It may be a slow process, but you have the goal of not wasting expensive fuel for burning water. This method is economically and environmentally perfect. After this, let’s see- how often to fill distilled water in inverter battery?

How Often to Fill Distilled Water in Inverter Battery? What If You Put Too Much Water?

Every inverter battery has an indicator that shows the water filler level. The green mark means there is adequate water in the inverter. Whereas, the red mark indicates the water is below the advised level. These marks are very important to determine how often to fill distilled water in inverter battery.

If your inverter shows a green mark, it means the water is filled till top off whereas the red mark means you need to top up distilled water in the inverter. But this has a catch, where the level should be a little below the Green mark but above the Red mark.

If the water level goes above the green level, it means the acid has diluted too much. This affects the working of inverters. Get it checked by experts. If you put in excess distilled water than is required, it can trigger the process of electrolyte dilution. This will decrease the battery performance of the inverter. Therefore, you should keep a check on the indicator and fill or refill the chambers carefully and slowly to avoid spilling and over-filling. It is an important thing after you learn how to make distilled water for inverter battery.

There are mainly two processes for making distilled water for inverter batteries. Solar and Fuel distillation processes involve the same process. Time taken by solar distillation ranges between 5-6 hours depending on the intensity of the sunlight. The fuel distillation process will take 2-3 hours but can vary depending on the quantity of distilled water you need. Here is the table for a quick reference of both processes. This table discusses the basics of both solar and fuel distillation thus its quite important in learning how to make distilled water for battery
