Since every one of us is dependent on electricity for most of our day, an adequate power backup supply for home becomes inevitable. The type of inverter is extremely important, but it’s the battery that’s the workhorse.

An inverter battery can make a day and night difference between the type of output you are getting, and hence it becomes critical to choose the best battery for inverter. There are different types of inverter batteries available in the market, and it can be confusing to zero down on the best battery for your inverter.

To help you make an informed decision, here are the parameters that will help you in buying the best inverter battery:

  • Load Requirements

Load requirement refers to the total power your appliances will consume when using an inverter and battery. The load requirements differ from one household to another, and you need to calculate yours accordingly. 

Let’s take an example where you need to calculate the load requirements of a modern home. Suppose you want to run 3 ceiling fans, 3 tube lights, 3 LEDs, 1 Laptop and 1 Television on your inverter battery. 

Appliances Power
3 Ceiling Fan 75*3= 225 watts
3 Tube Lights 40*3= 120 watts
3 LEDs 5*3= 15 watts
1 Laptop 100*1= 100 watts
1 Television 60*1= 60 watts
Total 520 watts

520 watts is the total load, hence buying a battery will be based on the given load requirements. 

  • Backup Time

When you are buying the best battery for inverter, you also need to know the backup time. Battery backup time is an important factor to consider. You need to buy a battery with enough capacity that can provide backup during a power cut. The backup time of an inverter battery is calculated in ampere-hours (Ah) and is divided by the capacity of the battery. 

  • Battery Capacity

Battery capacity determines the backup hours, and it is expressed in Ampere hours. To calculate the battery capacity, refer to the following formula:

Take 1.25 as the oversizing factor

Battery Capacity= (power requirements *backup-time)/ (battery voltage*battery efficiency*inverter efficiency)

(520*3*1.25)/ 12*0.8= 203 Ah

A battery rated at 203 Ah will be a perfect fit for the given situation. 

  • Battery Lifecycle

Battery lifecycle is another important parameter to consider when buying an inverter battery. It can be defined as the total number of charges/discharges cycles in a battery’s life. A battery lifecycle indicates the total percentage of battery that can be discharged. 

Invest in the Best Battery for Inverter for Your Home

These parameters will be helpful when buying an inverter battery as it will reflect highly on performance during a power cut. Always choose a reputed brand that offers superior quality products and excellent after-sales service. You can shop from India’s most cherished and trusted brands like Luminous. They offer a comprehensive range of different types of batteries. Here we have mentioned the best battery for inverter that they offer.

  • GEL Battery

It is a valve-regulated, maintenance-free lead-acid battery. These batteries are extremely robust and versatile. These batteries do not corrode easily and are spill-proof. They are an ideal choice for deep-cycle applications. 

  • Tubular Battery

A tubular battery is stronger, lasts longer, stores large amounts of energy, and has a greater run time. These batteries are highly reliable when compared to a flat-plate battery. 

  • Flat-Plate Battery

A flat-plate battery is like a lead-acid battery and is a suitable choice for instant high-current applications due to the large surface area of the plates. These batteries are affordable when compared to a flat-plate battery, and they offer good electrical performance. 

With an exceptional warranty, high life cycles, and excellent load capacity-these inverter batteries are made to last long!
