Load shedding has forced us all to secure our power supply.

In today's fast-paced world, uninterrupted power supply is crucial. Load shedding can disrupt daily life and business operations. In such scenarios, having a reliable backup power solution becomes paramount.

 Inverters, devices that convert stored energy into usable electricity during power cuts, have become essential. To ensure the effectiveness of inverters, the choice of battery is critical.

In this article, we will explore the best battery options for inverters during load shedding, their pros, cons, and which types are most suitable for different situations.

Types of Batteries for Inverters

When it comes to powering inverters during load shedding, several battery options are available.

Let's check out the options:

Typical Lead-Acid Car Batteries

These batteries are commonly found in automobiles and are designed to provide high bursts of power to start engines.

However, they are not optimal for prolonged power supply during load shedding. 

Their primary function is to deliver quick and intense bursts of energy, making them unsuitable for sustained use.

Using car batteries for inverters can lead to quick drainage and reduced overall lifespan.


  • Widely available.
  • Relatively affordable.


  • Short lifespan when used inverter applications.
  • Limited energy storage capacity.

Deep Cycle Lead-Acid Batteries ("Maintenance-Free")

Deep cycle lead-acid batteries are designed to provide a steady and continuous flow of energy over an extended period.

They are commonly referred to as "maintenance-free" due to their sealed design, which reduces the need for regular maintenance.

These batteries offer a balance between cost-effectiveness and performance, making them suitable for smaller home and office inverters during load shedding.


  • Decent energy storage capacity.
  • Suitable for moderate power requirements.


  • Limited lifespan compared to other advanced options.
  • Requires periodic replacement.

Gel Batteries

Gel batteries are a type of lead-acid battery that uses a gel-like electrolyte, which provides better stability and resistance to vibration.

These batteries are designed for deep cycling and are a step up from traditional lead-acid batteries in terms of lifespan and performance.

However, they might not offer the same efficiency and longevity as lithium batteries.


  • Longer lifespan compared to traditional lead-acid batteries.
  • Low maintenance requirements.


  • Lower energy density than lithium batteries.
  • Higher initial cost.

Lithium Batteries

Lithium batteries have gained immense popularity in recent years due to their exceptional energy density, longer lifespan, and lighter weight.

They are ideal for powering inverters during load shedding, especially for larger systems.

Despite their high cost, their longevity and efficiency make them a valuable investment for uninterrupted power supply.


  • Longest lifespan among available options.
  • High energy density and efficiency.


  • Expensive upfront cost.
  • Requires proper management to prevent overcharging and overheating.

Choosing the Right Battery for Your Needs

When selecting a battery for your inverter during load shedding, it's essential to consider your power requirements, budget, and long-term goals.

If you're looking for a cost-effective solution for short power cuts, deep cycle lead-acid batteries are a suitable choice.

They strike a balance between performance and affordability.

On the other hand, if longevity and higher energy capacity are your priorities, lithium batteries offer the best value over time, even though they come with a higher initial investment.


In conclusion, choosing the right battery for your inverter during load shedding can greatly impact the effectiveness and longevity of your backup power solution.

 While various battery options are available, it's clear that lithium batteries stand out for their exceptional lifespan and energy efficiency.

Despite being expensive upfront, their long-term benefits make them an excellent choice for those seeking uninterrupted power supply during extended outages.

 However, for smaller home and office setups, deep cycle lead-acid batteries provide a reliable and cost-effective option.

Remember, car-type lead-acid batteries are not suitable since they are designed to provide on short bursts of high power to start cars.

When making your decision, consider your power requirements, budget, and long-term goals to ensure you have a dependable backup power solution in times of load shedding.
