If you are affected by power cuts, an inverter is a product you are looking for. It is an appliance that provides power back up. Today, we all are highly dependent on electrical and electronic devices for daily activities. A power cut is enough to bring our lives to a halt. Therefore, the inverter has also become a necessity today. What is an inverter without its battery? It is quite important to decide which is the right inverter/battery for your home. Each home’s power requirement would differ. Thus, there is no one brand of battery that would suit all homes. Here, we shall see which is the best inverter battery, what are the factors one must consider while buying a battery inverter.

Best Inverter Battery – Buying Guide

Given the options that we have today, it can be quite confusing to decide the best batteries for the inverter. This decision cannot be made simply based on others’ preferences or advice. Therefore, here is a collection of important facts that one must look into before buying a battery for an inverter. We shall also see the important parameters and features that are present in the best inverter battery.

Factors to look for

  • Maintenance: Just like any appliance that is frequently used, inverters battery also requires proper maintenance. Irrespective of the brand of battery, you will have to maintain it. However, the ease or difficulty in maintenance depends on the design of the inverter battery. Generally, it is easy to maintain a tubular battery than a flat plate one. How long your batteries last is dependent on the amount of distilled water you can fill. In a battery with a tubular design, there is more room for distilled water. Thus, they last longer and maintenance is easy too. This brings us to the next factor – design.
  • Design: Inverter batteries can be broadly classified into two categories based on design – tubular batteries and flat plate batteries. (I) Flat plate batteries are compact and best suited for homes with a lack of space. However, as they are compact, they can hold only a limited amount of distilled water. They may have to be replaced frequently and require high maintenance. If you face short power cuts frequently, flat plate inverter batteries are a better choice. (II) Tubular batteries can hold a higher amount of distilled water. Inverter batteries with this design take up more space. Also, after a long power cut, tubular batteries require more time to recharge. Tubular batteries are recommended for homes that face power cuts for long hours. 

Note: Apart from these two types, a new kind of battery has become common today – the solar inverter battery. How is it different from the two types discussed above?

Solar batteries contain three electrodes. The base consists of a Lithium plate, upon which there are two layers of electrodes. Solar batteries are not exclusively meant for solar inverters. They can be used with any kind of inverter. While the regular batteries get their power from a source of electricity, solar batteries get their power from the sun. As awareness about renewable energy resources is spreading, many people are considering this type of battery as well, for their inverters. Solar batteries provide benefits which are discussed in the sections below. 

  • Type of cell: Batteries can have two types of cells – wet cell battery and sealed lead-acid cells. Sealed lead-acid batteries (SLAs) are expensive and do not require a high level of maintenance. Wet batteries on the other hand, although not very expensive, require maintenance. Do keep in mind that SLAs may be costly, but they are worth the price. 
  • Weight: It is recommended to buy heavier batteries. This is because heavier batteries are more durable. The electrolyte plates are of better quality.
  • Power requirement: You need to check which appliances you want to run when the power supply is lost. Note the power consumed by each of these appliances and calculate their sum. You can calculate the capacity of the battery requirement using this formula: Battery capacity = Power requirement (in watts) * Back up hours ( in hrs) / Battery Voltage (in volts)
  • Appliances that can be used: Lastly, the whole purpose of the inverter will be defeated if you use too many appliances when the power supply is cut. The inverter and the battery will not be able to handle the load and can provide power backup only for a few hours. Therefore, use only those appliances that are necessary. Do not overload the battery. It is a good practice to disconnect powerful appliances (such as a refrigerator) when there is a power cut. Also, try to connect only energy-efficient devices or those that consume less-moderate power. 

Batteries are an inseparable part of the inverter. Thus, it is important to purchase one that is made of high-quality components. Brands such as luminous inverter have been in the market for a long period and are reliable. In the next section, we will be discussing brands that have the best inverter battery and their features.

We have seen batteries from various leading brands in India. Apart from budget and features, certain other things need to be considered. For example, if you are facing space constraints, you can go for flat plate batteries. Otherwise, tubular batteries would be a good choice. These days, solar batteries are built with hybrid technology so that they can be used with both regular inverters and solar inverters. If you are upgrading the battery for your regular inverter but have plans to shift to a solar inverter int he future, you can go for a solar battery. These batteries provide several advantages over the regular types. 

Irrespective of the type, brand of the battery you buy, make sure that it has corrosion-resistant property. Electrolytes are like fuel for the battery and they need to be handled carefully. Thus, the battery has to have a safe design for the tubes so that it doesn’t leak. An unsafe design may lead to harmful events. 

If you want the inverter battery to last, maintenance is key. Even the best inverter battery can die too soon if not maintained well. Here are a few tips that may help:

  • The batteries tend to heat up when they are recharging or being used. Thus, it is important to store the battery in a cool and airy atmosphere. 
  • To avoid safety hazards, store the batteries away from inflammable materials/sources.
  • Regularly check the water level in the battery (one in a month/2 months). Refill with distilled water only. Any other kind of water will have impurities that will affect the battery. Also, do not allow the water level to drop to the minimum limit.
  • The battery surface should be free from dust. Keep it clean.
  • Use it regularly. Even in case of no power cut, discharge the batteries once in a while to enable smooth functioning.
  • Connect only the necessary devices for power back up. Do not load more devices to the inverter than it can handle. If possible, use energy-saving devices during a power outage.
