How Long Does Inverter Battery Charging Take?

If you recently invested in an inverter battery, you’re probably curious about a lot of things. But one question that most people have is – how long does inverter battery charging take? And it is an important one at that, as a battery is essential to an inverter’s efficiency and performance.

To give you a gist, inverter battery charging duration differs for all batteries, but there is a way you can calculate it. We know it sounds tedious, but it is fairly simple, especially if you’re good at math. Or not. And we will also discuss some maintenance tips for inverter batteries to help you get started!

How to Calculate Inverter Battery Charging Time?

The first step to calculate inverter battery charging duration is to understand the device’s C rating, which is the rate of time it requires to charge/discharge. The rating is typically defined as C10, C15, C20, and so on. Here, C refers to the capacity whereas the number (10, for example) is the time in hours.

Now, let’s assume that your battery has a capacity of 15o Ampere Hours (Ah). This means that the battery’s charging current will be 15A. Here’s how it is calculated:

Charging Current = Battery Capacity/C Rating

Thus, in this case, the charging current equals 150Ah/C10 = 15A

Now to calculate the inverter battery charging time, you need to divide the battery capacity by its charging current:

150Ah/15A = 10H 

This means that the approximate inverter battery charging duration for a 150Ah battery will be 10 hours. So, now that we’ve given you a detailed example, you can make your own calculations. However, make sure you use the right numbers and measurements to avoid any discrepancies.

Maintenance Tips for Inverter Batteries 

Since you now know how to calculate inverter battery charging time, here are some maintenance tips that can help ensure the battery keeps working efficiently:  

  • Keep the Terminals Clean: The first tip we have for you is to keep the battery terminals You can do this by cleaning the device with a dry cloth every day or on alternate days. This helps keep away dust, debris, and rust.
  • Track the Water Level: All inverter batteries require a certain water level to provide power backup, and it is crucial to keep track. If you find that the water level is below the minimum requirement, immediately top it up. However, it is important to always use distilled water.
  • Monitor the Acid Level: The best way to monitor an inverter battery’s acid level is to check the float indicators, which should have equal acid levels in all cells. Additionally, the color of the acid should be transparent, and if you notice the color is brown or black, always consult a professional.
  • Check for Loose & Damaged Wires: To ensure optimal inverter battery charging, you should regularly check for loose and damaged wires. If you notice any wires that are broken or crimped, it is best to have them checked for maintenance issues as such situations can lead to safety hazards like short circuits.
  • Keep Inflammable Objects Away: Another important maintenance tip for inverter batteries is to keep them away from inflammable objects like cooking oil and rubbing alcohol. Plus, you should also install the battery in an open and airy space instead of an enclosed one to ensure proper ventilation.

So, that covers the steps to calculate inverter battery charging time and some key maintenance tips.
