Things to Look for When Buying the Best Inverter Battery

One of the mistakes many people make at the time of buying a new battery is that they only focus on the cost and the warranty of the battery. And though these factors are important, one should also keep in mind some other important factors such as the type of battery that’s best suited for their needs, the battery capacity, battery efficiency, best inverter battery in India and likewise. That said, in this post we discuss, in detail, some of the most important things to look for when buying the best inverter battery in India.

Battery Capacity

Battery capacity is a measure of the charge it can hold. If you live in an area where there are frequent power cuts, you need a battery with a higher capacity. Reputable brands like Luminous that offer one of the best inverter batteries in India have three main categories of battery (based on capacity)

  • Below 150 Ah
  • 150-180 Ah
  • Above 180 Ah

Now if you want to know what is the right battery capacity for your home needs you should analyze your power requirement. To calculate your exact power requirement, you first need to determine what appliances or electronics you are going to operate during a power cut.

Let’s say these are the items you would be operating

Here’s a table with the list of appliances (along with the number of items and power consumed per appliance) you would need at the time of power cut.

Appliance / Electronics Power required

 per appliance / electronics

No of Appliance / Electronics Total Power Requirement per appliance / electronics type
Led light 7 Watts 8 56 Watts
Tube light 40 Watts 3 120 Watts
Fan 70 Watts 3 210 Watts
LED television 70 Watts 1 70 Watts
Refrigerator 140 Watts 1 140 Watts
  Total Power Requirement

 

596 Watts

Battery capacity =(power requirements *backup-time*aging factor)/ (battery voltage*battery efficiency*inverter efficiency)

Aging factor=1.25

Battery efficiency=0.8

Inverter efficiency=0.8

For lead acid battery, battery voltage = 12 V

Let’s say required backup = 2 hrs

Battery Capacity=(596*2*1.25) / (12*0.8*0.8)= 194

Since battery performance degrades with usage, you should buy a battery with a 5-10% higher capacity. A battery capacity of 200 Ah is what you would require in this case.

Battery Technology

Based on technology, inverter batteries can be categorized into 3 main types.

  1. Flat Plate Batteries
  2. Tubular Batteries
  3. Gel Batteries

Flat Plate Batteries

Flat plate batteries are just like any other lead acid battery. They are made of two flat plates – a positive and a negative. They are recommended for areas that experience rare power cuts. They are economical as compared to tubular batteries. Another advantage of flat plate batteries is that they get charged very quickly. However, they have a shorter life span, and therefore, come with short warranty periods.

Tubular Batteries

Tubular batteries are also a type of lead-acid battery. Unlike flat plate batteries that are suitable for areas with rare power cuts, the tubular batteries are designed to cater to areas with longer power cuts. They have a much higher life expectancy, and therefore, come with longer warranty periods. The best part about tubular batteries is that they are easy to maintain and require fewer water top-ups. The only limitations with tubular batteries is that they take more space and are more expensive as compared to flat plate batteries.

Tubular Batteries can be further classified into short and tall tubular batteries.

Gel Batteries

Gel batteries when compared to flat and tubular batteries are far more expensive. And that’s because gel batteries offer a more consistent backup. Also, gel batteries provide more power backup cycles. People prefer gel batteries, despite their high cost, because they are environment friendly and they emit minimal harmful gases. Another important feature of a gel battery is that unlike lead acid batteries that fail to provide the same power backup, as they age, gel batteries continue to perform the same throughout their lives. These batteries do not require any water top up or maintenance.

Warranty

The warranty is an important factor to consider when looking for the best inverter battery in India. The warranty period of a battery is the period for which the manufacturer offers free of cost service and repair.  Warranty, however, has no role whatsoever in the battery backup.

In case you buy an economical battery and at the same time cannot compromise on the battery capacity, you can go for a battery with a lower warranty. Reputable brands like Luminous offer a wide range of batteries that are available at different price points.

Looking for the best battery in India?

If you are looking for the best inverter battery in India and are unsure of where to go, it is advisable to go with the market leader Luminous. More than 11 million families in the country have shown their trust in the brand. So, look no further and check out the wide range of inverters and batteries Luminous has to offer.
