Buying Guide for the best inverter battery

While choosing the right inverter for your home is crucial, the perfect inverter battery’s choice is equally significant. The inverter cannot operate on its own without its batteries.

The choice of your battery also depends on your inverter and its capacity. It can be a massive challenge to select the right battery with the available options on the market.

Before purchasing your battery, it is better to be aware of the different terminologies. This buying guide will look into all these aspects. We shall start with calculating the battery capacity.

Calculate your battery capacity.

When you venture to purchase batteries, you encounter the term AH. What does AH represent? In simple words, AH is an acronym for Ampere Hour. It indicates the amount of power the battery can supply for a specific duration. For example, a 100AH battery can be expressed in various ways.

  1. 100 amperes for one hour
  2. 50 amperes for two hours
  3. 25 amperes for four hours

The formula for calculating battery capacity is as follows.

Battery Capacity = (Total Load in watts x Backup in hours) / (Voltage)

Load in Watts denotes the amount of power your devices in your home consume. In the case of an inverter battery, you calculate the load based on the devices you connect to the inverter. Thus, if you wish to connect five lamps of 40 watts each and three fans consuming 75 watts each, the practical power requirement is (5 x 40) + (3 x 75) = 425 watts.

Backup in hours indicates the amount of time you need as a backup. The more backup you need, the more is the battery size.

Voltage represents the voltage of a battery cell. In India, it is generally 12V because 24V and 48V batteries are not available here. If you need higher voltage, you can add multiple batteries.

This table should simplify matters for you to arrive at the ideal battery size for your inverter.

Power Requirement Backup required Suggested Battery Capacity
600 Watts Two hours (600 x 2) / 12 = 100AH
900 Watts Two hours (900 x 2) / 12 = 150AH
1000 Watts Three hours (1000 x 3) / 12 = 250AH

With the battery capacity calculations out of the way, let us discuss the different types of batteries available on the market.

Battery Types

If you go through our battery reviews, you will find terms like ‘Tall Tubular Battery,’ or ‘Flat Plate Battery,’ etc. These are some of the different battery types available today. Besides the two types mentioned above, you also have the ‘Sealed Maintenance Free’ batteries. These batteries have additional features. Let us discuss them in detail.

Flat Plate Batteries

You can refer to these batteries as first-generation batteries. Generally, these batteries are the most commonly used by Indians. These are the traditional lead-acid batteries with one lead electrode and the other lead dioxide. The electrode used is sulfuric acid.

These batteries are light and the most economical of all other batteries available on the market. These batteries have a disadvantage as they require comparatively more maintenance than others.

You have to replenish the distilled water in these batteries every three to six months, depending on your usage.

Delaying the refilling can end up damaging the battery. Of the different types of batteries available, the flat plate batteries are the most short-lived.

Besides, these batteries are comparatively unsafe to use because they regularly emit toxic gases when charging and discharging. Therefore, you need to place these batteries in adequately ventilated areas.

Inverter Compatibility is crucial

Before purchasing your inverter battery, it is advisable to check for inverter compatibility. The inverter VA depends on the total power required.

If you have an inverter with 150VA capacity and require a power backup for two hours, you need not invest in a 200AH battery. The minimum battery capacity should suffice.

It can be tricky comparing an inverter and battery combination. The ideal solution is to go for an inverter and battery combo, especially if you are purchasing an inverter for the first time.

Better to avoid local batteries

People tend to go for an excellent inverter but become stingy when purchasing a battery. They prefer a local battery because they cost less.

However, local brands do not follow the necessary safety standards, whereby they have a low lifespan. Besides, an inferior battery can pull down the inverter’s efficiency, as well.

The local inverter battery brands generally release toxic gases like carbon monoxide that can prove harmful to the household and the environment. The reputed brands ensure low emission levels, whereas the local brands do not guarantee it.

The local battery brands require a lot of maintenance and do not come with extended warranties. Many people opt for refurbished batteries. It is not advisable because they can be unsafe and do not have an extended lifespan.

An extended warranty is beneficial any day.

All home appliances come with warranties and guarantees. One should know the difference between these two terms. Guarantee entails that the manufacturer will replace the product for free if there is an irreparable fault within the specified guarantee period.

On the other hand, a warranty refers to the period where the user is eligible to avail of free repairs during the period.

Generally, inverter batteries come with two years guarantee and a three to four years warranty. It is advisable to choose a battery that comes with an extended warranty period.

Manufacturers like Luminous use the term ‘warranty replacement‘ instead of a guarantee. However, it is better to read the terms and conditions and understand them thoroughly.

Different warranty concepts

Manufacturers like Luminous offer different types of warranty like a Flat warranty and a Pro-rata warranty. For example, if Luminous offers a Flat + Pro-rata warranty of 75 months (60 + 15 months), it entails that the company provides free services for the first 60 months from the date of purchase.

Subsequently, the user can replace the old inverter battery with a new Luminous model and get a discount of a specific pre-determined value on the battery’s prevailing retail price. It is also referred to by some companies as ‘Buy Back’ value.
