Inverter Battery

Inverter batteries are designed to provide a small amount of current consistently for a longer period of time. Inverter batteries are not discharged over a much longer time. The performance and life of an inverter depend on its battery. As such a battery is a critical and main component of an Inverter battery. It is also known as UPS batteries. It could be either a lead-acid rechargeable battery or Lithium-ion rechargeable battery used with home Inverter.



The Home Inverter battery has two technology


1). Lead Acid Battery - The main component of the battery is the lead inside it. Higher lead ensures better battery performance and quality. Lead-acid batteries are not sealed and Maintenance-free hence it requires water top-up once in 3-6 month


 and 2) Lithium Battery – It has made of Lithium cells which has three forms a) Lithium-Ion, b). Lithium Phosphate, and  c). Lithium cobalt.

Inverter Battery Price in India 2021

An inverter battery costs Rs. 32,000/ kWh. A normal house needs a 4 kWh system to operate independently of the grid. So you can do your math to arrive at the total investment required for installing an Inverter battery at your home. Inverters typically cost Rs.5,000-6,000. According to a report published by IHS Market, the average cost of lithium-ion batteries will fall to Rs. 7521 ($100)/kWh in 2023.

Best Inverter Battery

Lithium batteries are proven to be the best option for inverter batteries lately.  These batteries have high energy density and the technology is witnessing significant cost reductions. It is a low maintenance battery and the self-discharge is also less. Lead-acid batteries lost the plot due to their dependence on hazardous metal lead and their low energy density. 

You can look into buying a Luminous (lithium) Inverter Battery for your home.

Battery Backup Time

The backup time of a battery depends upon Battery storage capacity measured in Watt Hour (Wh) or Kilowatt-hour (kWh)

battery backup time calculation

Generally, batteries are rated in AH and Voltage. To calculate watt hour, you should multiple, Battery ampere * battery voltage (12 Volt).


Power formula is (Wh) = Ampere * Voltage


For example,

150 Ah lead-acid battery and the battery voltage is 12 Volt.


The storage capacity is 150 AH * 12 Volt = 1800-Watt hour or 1.8 kWh.


The higher the watt Hour, the higher will be backup time. Usually, a 150 Ah/ 12-volt lead-acid battery gives around 3 hours of backup on 400-watt Power consumption.

In India, 150 Ah is the bestselling rating as it can last up to 3-4 hours if you use Led light, few ceiling fans, Led Television, mobile and Laptop charging.  For higher duration backup, one can go for the higher Ah battery.


Similarly, in Lithium battery – 80 Ah /12.8 Volt is the most selling lithium battery which has a storage capacity of 1,000-Watt-hour power. The backup time varies with a change in power consumption.

Inverter Battery Online

Earlier it was difficult to buy online as the technology was not water-proof and also bulky, so customers had to rely only on Local suppliers. But today you can easily buy online. The inverter battery is easy to transport with no damage.

Types of Inverter Battery

There are three types of battery


a) Tubular Lead-acid battery.

b) Solar battery

c) Lithium battery


There is no much difference in Tubular and Solar battery technology except warranty and life. The height of the battery determines the technology type, Tubular means tall battery and flat plate means short height battery.


Similarly, all solar batteries are C10 rated and Home batteries are C20 rated. Here c Stands for Charging


Contrary, the Lithium battery is the latest technology product available in India. It has many features over existing popular lead-acid batteries.

  1. Fast battery charging time – 2 – 4 hours
  2. Life cycle – 2 x than lead-acid batteries
  3. Storage capacity per / Kg – 3 x than lead-acid batteries

How to Choose Inverter Battery

If you are planning to buy inverter battery online and you do not have any idea how to choose a battery for your home. You should consider this before buying any battery


1) Battery Capacity measured in Ah (Ampere-hour) or Wh (Watt-hour)

2) Battery warranty

3) Price, depends on Battery Ah and warranty. 

4) Brand – A national brand having service support should be given preference


In the process of buying inverter with battery, the customer should first decide Inverter Capacity, it depends upon power consumption, if your power consumption is up to 500 watts, Inverter and UPS up to 1 KVA is the best to buy, the selection of inverter battery depends upon the duration of power backup time, if your home is having up to 4 hours of a power cut, Single /12v battery is the best buy, for long power cuts, go for Double battery Inverter system.  


UPS Battery Price

UPS or Inverter battery price depends upon Battery AH and Warranty, The price ranges from ₹4000 to ₹50,000. Lithium batteries will be the costliest compared to the tubular lead-acid battery because it is the latest technology product with higher energy efficiency and longer life. The other important factor which impacts the price of batteries in India are.

How does the price of Inverter Batteries vary on Battery Type?

Lead Acid Vs Lithium battery comparison

Factor Lead Acid Battery
Lithium Battery
Charging efficiency Low - only 70% Fast charged - 100% of capacity, A lithium battery can be charged 50% in just 30 minutes
Weight 30 kg/kWh 9 kg/ kWh, On Average, Lithium-ion batteries weight 3 times less than standard lead acid batteries
Maintenance High maintenance cost, Water top up required No Maintenance
Battery Life 500 - 1000 cycles 1500 - 2000 cycles
Safety Have no safety devices, are not sealed, and releases hydrogen during charging, in fact, the use is not permitted in food industry Releases no emissions, are suitable for applications

Battery Warranty

Inverter and battery are two different products, hence the warranty offered on Inverter and battery differs, usually, Inverter comes with 2 years manufacturer warranty and Inverter battery warranty varies from 2 years to 5 years depending upon Battery technology


The warranty on the battery is co-related with battery life. Higher warranty on battery will have a higher battery life.


In Lead Acid Batteries warranty has two aspects a) Replacement warranty and b) Pro-rata warranty is also known as buy-back warranty. If your battery fails during replacement warranty, Manufacturer such as Exide, Luminous, Okaya will replace it with a new battery and during pro-rata warranty period, a new battery is offered at a discounted price, which is, also known as buyback offer.


While in Lithium battery, there is no buyback offer, manufacturers such as Tesla, Loom, Panasonic will offer replacement of the battery in case battery fails or it does not give power backup
