Summers are here. The time of summer vacations. The time of the fresh summer breeze. The time of everyone’s favorite ice cream.
Unfortunately, this magic of summer of fades away the moment the power goes off. Summer vacation turns into a nightmare. Summer breeze turns into a heat wave. Ice cream melts into sorrows. Power cut overshadows the fun of summers.
It is that moment when an inverter system resembles the blessings from the Almighty. We can’t thank the inverter and batteries enough. However, we can take care of them in order to keep them performing without any glitch. As the summer changes your daily lifestyle, it also changes the way you take care of your inverter battery. Here are a few tips that will keep your inverter and battery running as the sun starts to lay its wrath.

Get batteries serviced or replaced in time – This simple suggestion can save you from big trouble. Call a technician and get your inverter unit examined. If all it takes is a little service than it’s perfect, but, if a replacement is your only option then do it without any delay. 

Let the inverter and battery breathe well– The temperature of the inverter battery rises during the charging process. It can lead to compromised battery life. According to research, with every 8­­­­oC rise in temperature battery life is reduced to half. Therefore, it is crucial to install the inverter and battery in a well-ventilated room which has enough air to control the battery temperature.

Check the water level of the battery regularly – Just like us, humans, inverter battery needs to stay hydrated during summers too. The battery must be refilled once every month during the summer season. Ensure that the water level is kept between the maximum and minimum level so that there is no spillage. Furthermore, make sure that never use the tap water or rainwater for refilling. The minerals and impurities present in above-mentioned water types can affect battery performance substantially.

These simple tips can ensure proper performance and maximum life for you inverter and batteries during summers. You can also buy the best quality battery from top-class brand like Okaya to ensure international standard quality. It reduces the risk of any glitch to minimum.

Okaya is also discovering innovations for a better tomorrow for everybody. Our UPS is a product that has been ingeniously built by adhering to safety norms, form factor, durability and performance. 

How does an UPS work?

A power UPS or UPS is created in such a manner that it changes direct current (DC) to alternating current (AC).The input & output voltage along with frequency and power capacity depend on the internal mechanism of the circuit. As a standalone unit, UPS does not generate power but only stores and distributes DC. 

Choosing the most befitting UPS for you, depends on the consumption of power at your home. Once you know this, picking an UPS is a piece of cake. 

 Battery: The heart of the UPS

The battery is the most essential component of the UPS. It directly impacts the performance of the battery and the life of UPS. Therefore maintenance and care of the battery should be a top concern. Batteries don’t add aesthetic or social appeal like furniture or decorations, but it runs the show from behind the curtains. 

How to choose an inverter? 

1)      Power requirement: As you read above, daily power consumption of your home determines the type of power you need. Number of electrical appliances in your home and each of its operational cost in terms of voltage must be ascertained. Example 1 tube light cost 60 watts to operate, or a TV takes 120 watts. 

Another thing to note is the VA rating of the UPS. Calculating the power factor is necessary and easily doable. Power factor is simply ratio of amount of power needed by an appliance to the amount of energy churned out by the inverter.  

2)      The type of inverter: Every inverter fundamentally converts DC to AC, however the type of AC that an inverter generates determines its character.
3)      Durability of the battery: As you read in the start, battery is the heart of the UPS. It is the quality of the battery that determines its longevity. Also, the capacity will determine the backup hours that you get during outage.

So next time you shop for a UPS Battery, make sure to consider these tips.

Lithium is a miracle metal. It is super light, and has an extraordinary electrochemical potential and has the highest energy density per weight.

Lithium has faced some backlash but has also garnered a lot of demand recently. With lithium-ion recently hitting the market, the energy density of which is higher than nickel-cadmium battery, is the lithium-ion best of the battery? Let’s find out! 

In lithium ion batteries the load character is amazing, its discharge is better than nickel cadmium. Its high cell voltage helps the battery pack for more energy in one cell. Unlike most forms of batteries, lithium ion batteries require no memory or schedule cycling to prolong and reset its battery life.

However, there is a minor drawback. That is, these batteries are fragile and require a circuit protection for safe operation. The protection puts a cap on the peak voltage during charging hours and prevent voltage dropping during discharge. Cell temperature is also monitored closely. Despite this, there is a risk of metallic lithium plating to occur. 

Another concern that lingers in the mind of the consumers relate to the age of the battery. It has been observed that despite non-usage, there is a bit of capacity deterioration noticeable after a year. After 2-3 years, the battery fails frequently. 

Due to these shortcomings, manufacturers are constantly working on ways to improve lithium-ion batteries by introducing ground-breaking and never experimented chemical combinations. With so many combinations being invented daily, computing the age of the battery becomes difficult. 

To slow the aging, manufacturers have recommended lithium-ion batteries to be stored at below 15 degree Celsius. Battery must remain at or above 40% charge at all times during storage. 

Here is a list of advantages that make a lithium ion battery a guaranteed winner:

  • Potential for yet higher capacities. Potential for higher capacity battery due to better energy density.
  •   Does not demand priming except for one full charge at the start.
  • Almost non-existence self-discharge when compared with nickel-based batteries.
  • Low to Zero Maintenance


Are inverter batteries and automotive batteries are the same? Can they be used interchangeably? If these questions sound familiar to you, then this article is for you. Unfortunately, most of the dealers are not technically sound enough to answer this question. Let us help you. For the starters, there is a huge difference between batteries made for vehicles such as car, trucks etc. and batteries made for UPS, inverter system and other power backup solution.

Before delving deeper, let us understand the fundamental difference between the utilization of abovementioned kinds of batteries. Automotive batteries power vehicles such as cars, buses and trucks are built to supply a huge amount of current for a very short period of time. It is generally for a few seconds for starting up the engine. Cranking the engine is the major task of an Automotive Battery and not anything else. Once the engine starts running, the alternator takes care of every power requirement and also recharges the battery up to its full capacity quickly.

Whereas inverter batteries, on the other hand, are engineered to continuously provide a minimally set amount of current for a longer period of time. The battery, as usually, stores the charge in Direct Current or DC form. The inverter system attached to it changes the stored DC power into AC or Alternating Current form, as most of our electrical devices are designed to run on AC. Now to achieve this, the UPS or inverter battery is discharged over a much longer time period as opposed to much lower potential as compared to vehicle or automotive batteries. It is due to this quality that inverter and UPS batteries are also known as Deep Cycle Batteries.

We cannot imagine our lives without an inverter system. Can we? Our life depends on electricity-driven gadgets and appliances. Therefore, it is imperative to buy the right inverter. But will that be enough? What about the inverter battery? Should you buy a tubular battery or lithium? What about maintenance?

Read this article to get answers to all the questions related to an inverter battery purchase.

•    Understand your power requirement
Power requirement must be the first thing that should come in your mind while buying a battery. To understand your power requirement you simply need to count the appliances you need running on the inverter and add their Watts. Finally, buy a battery with a capacity little more than your power requirement.

•    Find the right type of battery
There are a lot of batteries available in the market in terms of technology. Some of them are lead-acid batteries, tubular batteries, and maintenance-free batteries. First, understand the difference between them and pick the right one by consulting an expert.

 Lead acid batteries need regular maintenance and upkeep. You must check electrolyte levels regularly and keep refilling at a regular interval. 

Tubular batteries are handier as compared to the lead acid batteries. Hence, more expensive. These batteries require minimal maintenance work, promise higher efficiency, and longer service life.

Whereas, maintenance-free batteries are the sealed lead-acid batteries. They require minimal or no maintenance. These batteries are costlier as compared to abovementioned batteries and tend to have lesser scrap value.


•    Inverter VA vs. battery WA
VA represents the measurement of inverter capacity, whereas, WA speaks for the battery capacity. Ensure a proper match between these two measurements in order to keep all the desired appliances functioning. A mismatch between VA and WA rating can cause a problem and the inverter won’t be able to power the appliances that have more VA value in comparison to the inverter, even though the battery is powerful enough to handle the load. 

•    Finding the right brand
The market has a lot of inverter battery brands. But one should choose a brand that has years of experience and a trusted name in the international market. A brand like Okaya not only promises a top-class product but prompt customer service too.

An inverter system is one of the most helpful gifts that science has given to humanity. Just think about it; a system that runs all your major electrical appliances even when there is no power. If you are familiar with this comfort, thank an inverter system. Enough about the inverter! Another major component, or should we say the backbone of the inverter is its battery. It won’t be an exaggeration at all if we say that a battery is as crucial to an inverter as an engine to a car.

Therefore, it makes sense that you get familiar with the basics of a battery, as one day or another, you will find yourself buying one. This is exactly what this article aims to accomplish: to introduce you to the various types of inverter batteries.

1. Lead Acid Batteries

These are the most commonly used inverter batteries. You can easily find these batteries attached to an inverter at your home, office or school. There are many reasons behind the popularity of these batteries including their reasonable cost, light-weight and capability of producing ample amount of current. The maintenance of these batteries is quite easy too. One just has to check for the electrolyte and top it up regularly.

2. Tubular battery

Tubular batteries are the second most widely used inverter batteries in the market. Avant-garde design, best-in-class efficiency and longer service life are a few things that add on to these batteries’ popularity. Another amazing feature is that these batteries require minimal maintenance.

3. MF or Maintenance Free Battery

SMF or MF batteries are the safest batteries available in the market. These batteries are absolutely environment-friendly. Although, these batteries have a shorter service life as compared to ordinary lead-acid batteries, gradually these have become the preferred choice in the market. The reason is that these require no maintenance at all, as you don’t have to check and top up the electrolyte ever.

Now, when you have gotten quite a fair idea of the types of inverter batteries, it’s time to consider another major buying factor associated with the inverter battery i.e. the manufacturing brand.

An inverter has become a necessity or a big chunk of the Indian population. The demand for electricity has always been higher than the supply of it. That’s why power cuts are a normal scenario in most parts of India. Inverters come as the only economic solution that keeps the power going in case of power cuts. The efficiency of the inverter is highly dependable on the performance of the battery. If you have a battery that is in good condition and that has fast charging and slow discharging, you will get long hours of power backup. There are a few ways by following them you can increase the backup of your inverter battery and they are:

Don’t put extra load on your inverter battery. If not needed, switch off extra lights, fans or other appliances. It gives the battery a little rest that increases the power backup in long run.

Use energy saving appliances to increase the backup of your inverter battery. LED lights are the best for it. Instead of using traditional bulb or tube-light, go for energy-saving LED lights.

Keep the battery always clean to increase the power backup of your inverter battery. Rust and terminal corrosion are not good for a battery’s life. Rusting can reduce the in and out the current flow of the battery and it casts a negative effect on a battery’s performance. To clean the battery pour hot water and baking soda mix on the rusted area and rub it with a plastic brush. 

To increase the power backup of your inverter battery, keep it charged and hydrated. If you’ll leave the battery dry, it will get rotten. Don’t use rainwater or tap water, it can damage the battery. Keep the water level in your battery on top with distilled water. Okaya is the top inverter batterymanufacturer in India that makes batteries that get charged pretty fast.
