SMF batteries have numerous major advantages aside from the fact that they are maintenance-free. Among the most significant are:

  1. Extended battery life - SMF battery's main advantage is its extremely long service life. It can endure for as long as five years and even more if used properly. Thus, it eliminates the need to replace the battery once every year or two. You'll save money on new batteries because they last longer than regular ones.
  2. Compact Design - SMF batteries are built with high-grade materials and thoroughly controlled plate production to achieve maximum output per cell. Because of the greater density of energy, the force/volume and weight proportions are accurate.
  3. Maintenance-Free & Easy to Use - SMF batteries are low-pollution, user-friendly batteries that are also extremely safe for those who use them. Because these batteries are trouble-free and require no maintenance, it is not necessary to check the electrolyte levels. They do not need distilled water refills. It saves significant money and manpower that would otherwise be spent on battery maintenance.
  4. Pollution-free & Environmentally Friendly - SMF batteries do not generate any toxic fumes or gases. It does not spill because it is sealed, even during battery exports. SMF batteries from reputable brands are designed with all precautionary measures and are extremely safe to install indoors.

SMF batteries are indeed the best solution for your needs. Its battery plate is made of lead-calcium alloy that has a high discharge rate, great performance and reduced internal resistance. As a result of the zero delays in receiving and usage, these batteries serve as effective backup power.

Ways to Improve the Performance of SMF Batteries

To extend battery life, it is vital to regularly monitor battery performance. Here are some suggestions for improving battery performance.

  • The SMF battery must be kept in a well-ventilated area to minimize overheating. If the battery is mounted in equipment, it must be isolated from heat-generating components such as the transformer.
  • To avoid deep discharge, adjust the cutoff power to 11.5 volts in a 12-volt cell and 4.5 volts in a 6-volt cell.
  • It is critical to avoid a no-load battery drain. In the absence of a load, additional equipment components such as sensors, indicators and displays use power. If the equipment does not have automatic recharging, this power loss results in deep discharge.
  • Turbo cum float recharging is appropriate for SMF batteries. If power outages occur frequently, the battery must be charged instantly to ensure that it is fully charged before the next outage.
  • If a problem such as poor backup duration, battery heating, or low terminal voltage arises even after continuous charging, the battery has to be attended to promptly.
  • If the device is not utilized for an extended period, it must be recharged once a week. The battery's life can be prolonged to 3-5 years if it is charged and discharged often.

The Takeaway

The SMF battery is an excellent choice for users because of its high discharge rate, extended life, and lightweight design. It makes it suitable for any application. Aside from that, it requires no maintenance and has an exceptionally low self-discharge rate. Furthermore, their adaptability has resulted in more application-specific solutions for powering tiny devices, protecting power grids, and supplying power to transportation. These properties make SMF batteries ideal for consumers owning diverse equipment.

Everything You Need to Know Before Choosing an Inverter

Every individual in the entire world today is connected through the internet. Continuous technological innovations are bringing the world closer and closer. Power is the basis to keep this technological development working. Therefore, it is important to address the power failure issue with a suitable inverter. We have consolidated all the information that one should know before reaching out to a professional inverter battery manufacturer like Nantech power systems in Chennai. Keep reading about the various types of inverters, how they work, and aftercare procedures.

An Overview of Inverters

Inverters turn on various electrical devices even when the main supply is switched off. During power failure, they are emergency backups and convert direct current (DC) to alternating current (AC). The DC or direct current is created from either a solar panel or battery, which is converted into a 110/220 V alternating current and supplied to electrical appliances. DC is converted to AC because direct current can't travel for long distances. Every electrical equipment in a building will run on an AC current from the main power supply. Another advantage of AC is that it can experience both rise and fall and change its direction periodically, whereas DC can flow only in one direction. The voltage also reverses periodically in an AC circuit whenever the current changes direction.

How do Inverters Work?

Inverters store electricity in the form of DC in their batteries. When the power fails, the inverter starts to convert the DC to AC by passing it through a transformer. The change in voltage output instantly happens to resume the supply of electricity. Thus, as the direct current passes in an inverter, a series of switches turn on and off continuously and start stepping up with the help of a transformer. Then the switches alternate the DC signal's direction to create a sustainable AC voltage. Eventually, the electrical appliances gain a power supply even when the main power is shutdown.

Types of Inverters

Type of Load

Inverters are classified based on the output waveform and the load. Based on the type of load, the two main types of inverters are:

  • Three-phase inverter: Three-phase inverter is ideal for industrial use where the power load has three phases. These inverters produce 3 phase output alternating current with six diodes and three switches. Based on the conduction period of the switches, the current is divided into a 180 or 120 degree mode.
  • Single-phase inverter: As its name suggests, single-phase inverters have only a single phase of power load. They have alternating switches to counterbalance them. A single-phase inverter is classified into a full-bridge inverter and a half-bridge inverter. The full-bridge inverter has four feedback diodes and four switches. The current load is balanced by automatically switching off two switches when two of them get turned on. They determine whether the half cycle of the voltage is positive or negative. On the contrary, a half-bridge inverter has two switches connected to two diodes that decide the cycle of the voltage output.

Type of Output Waveform

Depending on the output waveform, there are three classifications in inverters. They are:

  • Pure Sine Waveform: Sine waveform inverters are ideal for taking heavy loads. Most of the electrical appliances we use in our daily life are compatible with sine waveform. Thus, investing in a pure sine waveform inverter is always a good option. However, they are quite expensive, and pure sine wave inverters are available at a much higher cost than the regular ones.
  • Modified Sine Wave Inverter: A modified sine wave inverter is another type that can work with almost every electrical appliance. But it has the disadvantage of reducing the device's efficiency. However, these inverters are priced reasonably to suit the budget of the normal population. Another fact to consider is that the modified sine wave inverter is not ideal for appliances that require high power, like motor pumps, air conditioners, and refrigerators.
  • Square Wave Inverter: Square wave inverters are the most affordable as they are very cheap. But a square wave inverter is not compatible with many electrical appliances and has very less efficiency. Thus, they are not preferred by many people.

An Insight Into the Importance of Batteries & Its Kinds

The battery is the workhouse and backbone of an inverter. The life, performance, and efficiency of an inverter solely depend on the quality of the battery. The battery is the heart of the entire inverter system to determine the backup time. A good quality battery will offer the best solution during power failure and ensure low maintenance along with high reliability. There are three types of batteries used in an inverter, and they differ based on the technology to store the current. By knowing them in detail, you will be able to choose the right one for your usage.

Flat Plate Battery

Flat plate batteries have two electrodes and are commonly referred to as lead-acid batteries. The electrodes are immersed in water and sulphuric acid, an electrolytic solution. The positive electrode contains a lead oxide, whereas the negative electrode is made of porous lead. Flat plate batteries are lightweight and cost between nine to fifteen thousand Indian rupees. These batteries need regular maintenance, which is a major disadvantage. Therefore, tubular batteries have replaced flat plate batteries in recent times.

Tubular Battery

Tubular batteries are seen to last for a longer duration than flat plate batteries. They have a life of five years and are very efficient with less maintenance. The deep charging cycles enable these batteries to perform with greater efficiency. Tubular batteries need fewer water top -ups and are more reliable compared to the flat plate battery. However, tubular batteries cost more than flat plate batteries and are available between nine to twenty-five thousand Indian rupees.

Sealed Maintenance-Free Battery

A sealed maintenance-free battery is also known as valve regulated lead acid battery or VRLA. The reason why many prefer a VRLA battery is that it requires no maintenance. There is no need to replenish the electrodes with distilled water, and they are very safe for usage as they do not give out obnoxious gases. But the sealed maintenance-free battery is very expensive compared to tubular and flat plate batteries. The disadvantage of these batteries is that they have a shorter life.

Tips to Choose the Right Inverter

If you are confused about choosing the right inverter, the points mentioned below will help.

  • The first step will be to calculate your power requirements. Identify how many devices you have, including the charging points, Wi-Fi routers, fans, and bulbs. Find out the overall power consumption and then decide the right inverter for your home.
  • The capacity of an inverter is different from the power consumption. The capacity stands for the maximum load an inverter will be able to handle when every appliance is in use simultaneously. Therefore, you should always pick an inverter that has a higher power capacity than your overall power requirement. Study the capacity of various inverters available in the commercial market and choose wisely.
  • Battery size plays a major role in satisfying all your demands. Correct battery size will provide the right backup without hindrance for longer durations. You have to calculate the battery size depending on how much time you want the power backup for your home.

The Bottom-line

With the above details, you would have understood all that you need to know about inverters. Now you can easily purchase the right one that suits your requirements and demands. However, make an effort to identify the inverter that will be perfect for daily usage and carefully look into its maintenance criteria before purchasing.

Everything You Need To Know About Tubular Batteries

What are tubular batteries?
Tubular batteries are also known as deep discharge batteries is a lead-acid battery. They provide a small amount of current, for example, 5 Amperes, for a long period of time. The electrodes of these batteries are thicker than the regular ones and hence cannot release a large amount of current. Moreover, they cannot be used in domains where a large amount of current is required in a relatively short period of time. Although they don’t provide high current, they last for a longer duration as compared to regular flat plate batteries.

Inverter Batteries: What Should You Know Before Getting One?

Power cuts and load shedding can be quite troubling. And getting an inverter-battery setup helps a lot. But choosing an inverter battery might be a daunting task for most of us, especially if you are getting it for the first time. Don’t worry, we at Nantech decided to put this comprehensive guide and here’s everything you need to know before getting one:

How Long Do You Need A Power Backup?

Knowing how long you need the power backup to last, helps you choose the battery with the right capacity. Let’s say you face power cuts for 2 hours everyday and you need a 12V battery as a power backup for the entire time. And you want to run the following appliances:

Appliance Quantity Power Consumed
Desktop Computer 1 155W
Fan 1 75W
Tube light 2 20W
Total 155 + 75 + 2*20 = 270 watts

Required Capacity of Battery = (Hours of Power Backup) * (Power Required in Watts) / (Voltage of Battery)

Required Capacity of Battery = 2 * 270 / 12 = 45 Ah

Most batteries in the market are around 135-150 Ah and if the above case is equivalent to your real requirement, then you can even go for cheaper and lower capacity batteries!

It is essential to calculate and decide the budget as per your requirements, since the inverter and battery dealers may persuade you to buy more expensive batteries. The above example will help you with the necessary calculations and prevent unnecessary expenses.

Battery Type
Lead Acid Battery:
These are of two types:

  • Flat plate battery: recommended for areas with frequent power cuts, lasting short durations.
  • Tubular battery: it’s bigger than flat plate battery and is recommended for areas with power cuts lasting long durations but fewer in frequency.

Gel Battery:

  • Recommended for offices and homes where power backup lasting several hours is necessary.
  • Zero reduction in performance, even after years of usage.
  • No water top-up and maintenance required.
  • Easy installation.
  • Eco-friendly battery with minimal toxic emissions.
  • No chance of acid spillage!

Weight of the Battery

The weight of the battery is something you might overlook and not take into consideration first but it tends to be an important factor for those who are frequently on the move! Batteries have different weights when they are filled and empty(dry). If you frequently shift places, consider buying a less bulky battery. In case you still need a heavy battery, look for the ones equipped with a trolley.

Replacement, Warranty and Services

Most reputed companies offer free services within the warranty period (also called ‘flat warranty period’). In case your battery faces issues within a few months of purchase, it could be replaced, provided the fault occurs and is registered within the replacement/pro-rata warranty period. It also helps if the company provides installation and maintenance services, since this can be a tough task for most individuals. Hence, warranty period is also an important factor while purchasing a battery!

We hope this comprehensive guide helped you and made the task of buying a battery easier! If you are looking for an authorised battery dealer, we at Nantech sell batteries of numerous reputed companies.

Simple Solutions To Most Prevalent Inverter Battery Issues

Inverter Battery Woes? Let Us Help You Solve It

Inverters in Chennai are essential. No home or office can do without them because a single power cut means all the gadgets and appliances; we rely on every day become useless. Inverters provide the power back-up necessary for a continued supply of electricity to them.

But like any other machine, inverters are also prone to common problems. In this article, we explore the solutions to the most common issues that crop up in inverters and batteries.

Why Is Your Inverter Not Turning On?

These are the possible reasons along with remedies why your UPS or inverter is not switching on:

  • The battery is not connected. Ensure that the connection is made correctly.
  • The terminals of the battery are loose. Make sure that they are tight and precisely fit.
  • The terminals of the battery are loose. Make sure that they are tight and precisely fit.
  • The inverter is tripped. In this case, all you need to do is press the reset button on it.
  • The battery has a fault. The solution is to replace it.
  • The terminals are rusty. Clean out the corrosion for the inverter to work suitably.
  • The terminals are reversed. Use the inverter manual to connect the right terminals.
  • The battery has become very weak. You will need to charge it. In case the battery is very old, you might need to replace it.
  • The battery is completely discharged. The solution here is to charge for some hours before switching the inverter on.

Why Is Your Inverter Battery Not Charging?

The most common cause of battery not charging is because it is dead. You will have to replace it for the inverter to work. There are three other reasons for it:

  • The fuses have melted. You will need to replace them.
  • The rectifiers are burnt. You will need to take the inverter to the service centre.
  • The battery connection is loose due to corrosion. Clean the terminals to remove rust and then clamp the connection firmly.

Why Is Your Inverter Making A Beeping Noise?

  • An inverter makes a beeping noise when it runs on the power of the battery. The sound is like an alarm that indicates that the inverter has transferred from normal electricity to battery operation. Since this is just an indicator, there is no problem to solve.
  • When the battery of the inverter is very low, it begins to beep. The sound tells you that the inverter will shut down pretty soon unless you charge the battery. The inverter is forced to shut down to prevent the battery from being discharged too much. Generally, the beeping begins two minutes before shut down. The solution here is to recharge the inverter for a few hours. It will stop the beeping sound.


  • One more reason your inverter may be making a constant beeping sound is capacity overload. When there are too many gadgets and appliances connected to the inverter, it reaches an overload condition. The beeping is an alarm to inform you of the same. There are two remedies to this problem. One, you can remove all non-essential devices from the inverter. Two, you buy a new inverter that has sufficient capacity to take a load of all the equipment at your home or office. The right size inverter will never beep due to capacity overload.
  • One last reason the battery is beeping is a failed self-test. This is not a common cause, but it does happen. Every 14 days, the inverter conducts a self-test. The test checks the integrity of the battery. If the test fails, the inverter starts beeping. This happens when the battery is near the end of its life. The solution is to get the battery replaced within one month.

In Conclusion:

The reasons described in the post above are some of the most common problems that people face with inverters. Thankfully, a majority of them have simple solutions that can be done at home. If that fails, then an inverter repair centre can resolve them quickly.

Also Read: How Useful Is The Inverter?

That said, it should be noted that each issue, like a beeping sound or not charging, may have a different symptom and underlying reason. For instance, if the inverter is making one, constant beeping noise it means capacity overload. Whereas, if the battery beeps in a continuous manner, then the battery is low. Essentially, you have to pinpoint the symptom to get to the issue.

If you are unable to remedy the problem at home, it is highly advised to take the inverter to a supplier in Chennai. They will have experts who can find the issue in a matter of minutes and give you a solution for it!
