Power cuts during summer are almost a given everywhere and bearing the dry heat can be strenuous on all. What if you could solve it all with the right inverter and the best inverter battery to go with it?

Inverters are a must in every household and how long your inverter is able to power your home appliances is determined by the capacity of your inverter battery. But don't inverters have a built-in battery, like a UPS? Why should buy another battery with it then?

Well, unlike a computer UPS which is a compact device, an inverter is designed for larger loads that can power more powerful home appliances like a refrigerator, television and more. That's why the actual inverter itself has just the conversion and charging circuitry and hence the battery needs to be kept exterior to it.

Before you buy yourself the best inverter battery, here are a few things to look for. Start with the battery technology so that you can pick one that fits your budget. Next, calculate the power requirement of all the home appliances that you want running during a power cut. To know more about this check the dedicated buying guide to the best inverter battery at the end. Make sure you also read up the buying guide to the best inverter in India.

To find the best inverter battery for you we read through multiple customer reviews on Amazon and Flipkart while also checking up various inverter battery manufacturer pages for any recent developments in the field. 

Best inverter battery

Amaron Current AAM-TT Inverter battery

Affordable, powerful and maintenance free

Amaron has done very well in the automotive battery segment with their “ Lasts long, really long” tagline for their maintenance free batteries. With the Amaron Current series of batteries, they have got the same formula to the inverter battery segment.

Buying Guide to the best inverter battery

When you are out to buy a new inverter, apart from the inverter itself the main part to look for is the inverter battery. This is because the inverter battery will determine how long you can run your home appliances for. And the specification that determines this is the battery capacity which is measured in Ampere Hour (Ah).

Before you pick which capacity of inverter battery to go for, here are a few quick calculations which will come handy to help you buy better.

Home appliances as we know consume a certain among of power (measured in watts (W)), for example, a basic computer can consume around 250 Watts, a television takes around 120 Watts, a ceiling fan around 80 Watts and so on.

Now you have to start your calculations by adding up the wattage of all the appliances you want to be turned on during a power cut. Assume two ceiling fans (160 watts), two tube lights (80 Watts), a television (120 watts) and a computer (250 watts). This gives you a total of 610 Watts which we can consider as an average load for most households (during a power cut and power requirement for two rooms).

Once you get the total power requirement, next you must determine for how long you want the appliances to run (in hours). So our calculation is as follows.

Total Power Requirement (P) = 610W

The time required (T) = 2 hours (assume you want the inverter to power your home for two hours)

Therefore, the battery capacity needed (BC) = 610W x 2 hours = ? Wh

But as we said earlier, the battery capacity needed is in Ah nor Wh, So we need to convert the Watts into Amperes by using the formula,  

Power (W) = Voltage (V) x Current (A)

Therefore, Current (A) = Power (W) / Voltage (V)

Current (A) = 610W/ 12V = 50A

Therefore, the inverter battery capacity needed (BC)  = (610 W / 12V) x 2 hours = 101.67 Ah

This shows that you will need a 120Ah battery to run your home for 2 hours. similarly depending on your load you get batteries of 100Ah, 150Ah, 220Ah. Always make sure to pick a battery capacity that is slightly more than your usage.

Also remember to pick the appliances you want to run on your inverter carefully, large appliances like an air conditioner or refrigerator

The next thing to look for is the type of battery as follows:

  • Flat plate inverter battery: The older generation battery technology, needs the most maintenance, more regular water top ups, more ventilation but weighs less and is priced really affordable. But their low life of around 3 years has pushed people towards tubular batteries. An example of this is the Exide Insta Brite inverter battery we have recommended above. 

  • Tubular inverter battery: Boasting long life of up to 5 years, tubular batteries require lesser maintenance than flat plate batteries, but weight more than them. Tubular batteries are the most popular type of inverter battery around due to their pricing and range of brands available like Amaron, Exide, Luminous, Su-Kam. An example of this is the Luminous RedCharge inverter battery we have recommended.

  • Maintenance free inverter battery: The latest generation of batteries require low maintenance, have better safety, require no ventilation and last for 3-4 years. You can find MF batteries from Luminous which star upwards of Rs.10000. The Amazon Current inverter battery is a good example of a maintenance-free battery that we recommended above. 

Once you have got yourself an inverter and a sizeable inverter battery to go with it here are a few tips to ensure the long life of your devices:

  • Follow the maintenance guidelines strictly, this includes topping up/ replacing the distilled water at regular intervals. Some inverters themselves keep track of the water levels and informs you when the levels are low

  • Make sure the load on your inverter is lower than the capacity of it, otherwise your appliances will simply not run.

  • Do not disconnect the battery when the inverter is running

FAQs


  • Can I use it for 650Kva, 800Kva, 900Kva, 1100Kva, 2 kva inverter?
    Make sure the battery capacity nearly matches the inverter specifications, do not buy a very powerful inverter and feed it with a small 50Ah or 100Ah battery. Check our best inverter in India article to know more.

  • Is it delivered to my place?
    Make sure you clearly enter your pin code before buying as sometimes batteries are not delivered to some places due to their design. Alternatively, you can just pop into your local inverter battery shop.

  • Do you take the old battery?
    Yes, companies do offer an exchange offer, but only in some cities. Usually, you will have to contact the Amazon/ Flipkart directly to know more.

  • What is the warranty? And what is a pro-rated warranty?
    The warranties offered are as follows:

    Amaron: 0-36 Months Free + 37-48 Months pro-rated warranty

    Luminous: 0-18 Months Free + 19-36 Months pro-rated warranty

    Exide: 0-18 Months Free + 19-36 Months pro-rated warranty

    The pro-rated warranty is a period of warranty during which if the battery falters, the company will offer you a new battery at a discounted price (not free)

  • How many appliances can the battery run?
    How many appliances you can run and for how long depends on the capacity of the battery and the power consumption of those devices. Check the buying guide above to know more.

  • What is an inverter trolley?

    An inverter trolley is a basic stand with wheels wherein you can mount your batteries and the inverter for easy movement.
