Myths about inverter batteries:
- Myth 1: Wet batteries need constant water topping — in reality, topping is required only every couple of months for a 150AH 12V battery.
- Myth 2: Tap water can be used — false; only distilled water should be used to maintain battery life.
- Myth 3: Temperature has no effect — incorrect; extreme heat or cold impacts performance; batteries with automatic temperature compensation perform better.
- Myth 4: Battery should be fully discharged before charging — wrong; full discharge reduces the battery’s ability to hold a charge.
- Myth 5: Any battery charger works fine — not true; a high-quality inverter with multi-stage charging extends battery life and prevents over/undercharging.
Conclusion
Ensuring that you have a constant supply of electricity to your home is a top priority and that is why you want to consider buying one of the best inverter batteries in India so that you have a reliable source of backup energy.
You won’t need to be told how important an inverter can be if you live in an area that is impacted by regular power cuts but you might have heard certain things about inverter batteries that affect your thinking, but actually, turn out to be wrong.
5 Myths about Inverter Batteries
Here are some of those common myths about inverter batteries:
01. Constant Watering is not a Good Idea
One of the most popular misconceptions is that if you have one of the most common types of inverter in the form of a wet battery it requires regular topping up of the water.
This is not the case. You do need to keep the water levels topped up for maximum efficiency but not as frequently as some suggest. Ideally, a typical 150AH 12V battery only needs topping up with water every couple of months.
02. Using Tap Water in Inverter Batteries is not Fine

Most definitely not! Your inverter battery does need topping up with water, as you know, but don’t listen to any advice that tells you that filling it up with tap water is fine.
You always need to use distilled water in your battery. Using tap water will greatly reduce the lifespan of your battery.
03. Temperatures do have an Impact on Battery Performance

Another common myth about inverter batteries is that the temperature outside will not have any impact on the performance of your battery.
It would be wrong to believe that extremes of temperature won’t make a difference to your inverter battery. Your battery requires a constant temperature that is neither too hot nor too cold, and the best way to achieve this aim would be to buy a model that offers automatic temperature compensation.
The sensor can then ensure that you don’t suffer from overcharging or undercharging as a result of temperature extremes.
04. You should not Attempt to Fully Discharge your Battery Before Recharging
Another thing you might have been told about your battery and maintenance would be to make sure inverter battery fully discharged before charging it up again. This is another myth.
If you follow this poor advice you will end up impairing your battery’s ability to hold a charge.
05. Always Buy a Good Battery Charger

You might also have been told that the quality of your battery charger is not that relevant, but that is not the case.
The quality of the inverter is actually very relevant when it comes to getting maximum performance and longevity from your battery.
What you should look for is an inverter that delivers multi-stage charging as this ensures that your battery is not at risk of under or overcharging.
Conclusion
As you can see, it makes sense to invest in a decent inverter battery so that you get the best backup security. It is also a good idea to steer clear of some of the advice about looking after your battery that could actually be harmful to it.

FAQs On Popular Myths About Inverter Batteries
1. How Often Should I Top Up Water In An Inverter Battery?
A typical 150AH wet battery needs water only every 2–3 months, not frequently. Always maintain the recommended level.
2. Can I Use Tap Water Instead Of Distilled Water?
No. Only distilled water should be used. Tap water reduces the battery’s lifespan due to minerals and impurities.
3. Does Temperature Affect Inverter Battery Performance?
Yes. Both high heat and low temperatures reduce efficiency. Batteries with temperature compensation are more reliable.
4. Should I Let The Inverter Battery Fully Discharge Before Recharging?
No. Deep/full discharge damages the battery and weakens its ability to hold a charge.
5. How Important Is The Quality Of The Inverter/Charger?
Very important. A multi-stage charger ensures proper charging, prevents damage, and increases battery life.
