8 Ways to Prevent Your Inverter From Draining Its Battery

Blog Details / Home

In today’s world, where power outages can disrupt our daily lives, the role of inverters has become indispensable. The machineries provide a backup power source, allowing us to continue with our essential tasks even during blackouts. However, to ensure that your inverter serves its purpose efficiently, it’s crucial to prevent it from draining its tubular inverter battery prematurely. In this blog, we will explore various ways to maintain and prolong the life of your inverter battery, helping you get the most out of your investment.

Choose the Right Battery

Selecting the right type of battery for your inverter is the first step to ensuring its longevity. Tubular inverter batteries are known for their durability and efficiency. They are designed to withstand deep discharges, making them a suitable choice for inverters. When purchasing a tubular battery, consider factors like capacity (Ah), brand reputation, and warranty. Investing in a high-quality battery will pay you off in the long run.

Proper Installation

The installation of your inverter and battery is critical to its performance. Ensure that the installation is done by a qualified battery installer who follows the manufacturer’s guidelines. Proper ventilation is essential to prevent overheating, so place the inverter and battery in a well-ventilated area. Additionally, keep the battery away from direct sunlight and moisture.

Regular Maintenance

Regular maintenance is key to preventing your inverter battery from draining prematurely. Here are some maintenance tips you can follow to prevent your inverter battery from draining.

Check Water Levels: 

Tubular batteries require periodic watering. Check the water levels in the battery cells regularly, and top up with distilled water as needed. Neglecting this can lead to reduced battery life.


Dust and dirt can accumulate on the battery terminals, leading to poor connectivity. Clean the inverter battery terminals periodically to ensure a strong connection.

Terminals and Cables:

Inspect the battery terminals and cables for any signs of corrosion or damage. Clean or replace them if necessary.

Proper Charging

One of the common reasons for premature battery drain is improper charging. Here’s how to ensure your battery is charged correctly:

Charge Timings: 

Set a regular schedule for charging your inverter. Ideally, charge it during off-peak hours when the grid power supply is stable and voltage fluctuations are minimal.

Full Charge: 

Ensure that the battery is charged to its full capacity during each charging cycle. Most inverters have indicators or display panels that show the battery’s charge status.

Avoid Overcharging:

While it’s essential to charge the battery fully, avoid overcharging as it can damage the battery. Modern inverters often come with features to prevent overcharging.

Use Energy-Efficient Appliances

The appliances connected to your inverter play a significant role in how quickly the battery drains. To maximise battery life, use energy-efficient appliances. LED lights, energy-efficient fans, and inverter air conditioners consume less power and, therefore, put less strain on the battery.

Manage Load Wisely

Overloading your inverter battery can lead to faster battery drain and reduced battery life. Be mindful of the inverter battery uses and the total load connected to the inverter. Ensure that the appliances you connect do not exceed the inverter’s capacity. Some appliances, like refrigerators and air conditioners, have high starting currents, so keep this factor into your load management strategy.

Regularly Use and Maintain Your Inverter

Inverters and batteries are designed to be used regularly. If left idle for an extended period, the batteries can deteriorate faster. Even if you don’t experience power outages frequently, it’s a good practice to run your inverter occasionally to keep the battery active and in good condition.

Install Voltage Stabilisers

Voltage fluctuations are common in Nigeria, and they can damage your inverter battery over time. Installing voltage stabilisers or surge protectors can help regulate the voltage supplied to your inverter, ensuring a stable and safe charging environment for your battery.

Star Plus Tubular Inverter Batteries 

Star Plus Battery is one of the leading inverter battery manufacturers in Nigeria. Our batteries are known for their deep discharging capability and longevity. On average, a Star Plus tubular inverter battery has 20% more electrical capacity than other types of batteries, and its self-discharge rate is as low as it only loses 12%-15% charge in a month when not in use. If you are looking to buy an inverter with a battery, choose Star Plus batteries to ensure a reliable power supply. Our batteries boast a long service life of up to 7-8 years and come up with a 24-month warranty as well.

Wrapping It Up 

Your inverter battery is a crucial component of your backup power system, and taking steps to prevent it from draining prematurely is essential. By choosing the right battery, maintaining it regularly, using energy-efficient appliances, managing your load wisely, and investing in solar technology or voltage stabilisers, you can maximise the lifespan of your tubular inverter battery. Remember that proper installation and charging practices, as well as regular monitoring, are key to ensuring your inverter battery serves you well for years to come.
