7 Best Inverter Batteries For Home And Office With The Highest Capacity

The summers are here and power shortages and voltage fluctuations will be common. These are damaging to electrical appliances. Sudden power cuts can be devastating in workplaces as well. Productivity takes a hit if employees aren’t able to back up their files in time.

You want the best inverter to beat the summer heat; to save your electrical appliances, and most importantly; to maintain work continuity. See this guide to learn the importance of a good battery and how to choose one with the maximum longevity and the lowest maintenance.

Importance of an inverter battery

The importance of the battery market in India can be gauged from the tremendous growth in the domain. The market is pegged to grow at a massive CAGR of 16.80% between 2024-2029. Currently, it stands at $US 7.2 billion and is about to reach $US 15.65 billion.

Investments in battery technology have gone significantly up in the last decade. Companies are backing R&D activities to improve battery technology in the wake of rising demand for long-lasting batteries. Here are the circumstances in which these batteries prove inevitable:

1. During power outages

Every year India suffers major power outages during the summer season. States in the Gangetic plains see a surge in power consumption and discoms aren’t able to keep up. Battery backup becomes critical during such situations and inverter batteries are needed.

2. In the event of a grid failure

Almost all the states in India experience grid failure due to various reasons. It could be due to cyclones or thunderstorms, or it could be due to overheating problems. An inverter battery is what keeps the power on and prevents any disruption.

Factors to consider when choosing an inverter battery for home or office

The importance of an inverter battery, especially in a tropical country like India is doubtless critical. With the rising demand for inverter batteries has emerged the need for quality inverters. Poor-quality batteries are flooding the market in a demand-rich scenario. How do you choose a quality inverter in this case?

Here are the features you should look for while buying an inverter battery:

1. Capacity

The capacity of an inverter battery means how much charge it can store. It is measured in Ampere-hours (Ah). A 300 Ah battery is the most desired product in the market right now as it has the maximum storage power.

2. Battery Technology

Inverter batteries are of two major types - tubular and flat plate. The tubular battery is technologically more advanced and lasts longer than the flat plate battery. The efficiency and low maintenance of tubular batteries make them the ideal choice.

3. Warranty

Always look for an inverter battery that comes with the maximum warranty period. Most companies provide a 5-year warranty that is divided into a free-of-cost period and a pro-rata period. Some companies also provide a full period warranty.

4. Charging Time

The efficiency of a battery is determined by how long it takes to recharge. You want a battery that recharges quickly - one that is operating at peak capacity during power outages and grid failure situations.

5. Brand and price

An inverter battery is a hefty investment so choosing the right brand is essential. It is always better to buy an inverter battery from an established brand. Of course, the price considerations are important but accepting a quality trade-off should be avoided.

6. Compatibility with inverter

Your inverter battery should be compatible with your inverter. See the specifications carefully before you invest in one. Make sure the battery voltage and the inverter voltage are similar and whether the capacity and charging standards are proportional or not.
