Best Inverter Battery – Buyer’s Guide:
When it comes to purchasing a battery for home, there are some significant factors which you need to understand before buying. We explained below each and every vital factor that is responsible for battery capacity and life.
Flat Plate vs Tubular Plate vs SMF batteries:
The positive grid/plate design is the core of battery power and life. There are generally two types of a plate designed used by most of the inverter battery manufacturers. Hence, first of all, you should know what exactly are the differences and advantages of flat plate or tubular plate batteries.
The basic difference between a flat plate and tubular plate batteries lies in their design and structure.
Flat positive plates are grid/ mesh types structure in which lead dioxide is filled uniformly.
On the other hand, tubular positive plates consist of a series of vertical tube-like shapes connected to a single bus connector. The active materials are collectively held in a micro-Porous, non-conductive tube called the gauntlet.
All in all, tubular batteries are collectively built with the gauntlet, bottom bar, spines so that it keeps the active material mechanically together. Such unique and technical structures of tubular batteries make them superior over flat plate batteries.
Please note that the negative plates of all lead-acid batteries are of flat pasted types.
The table below shows a comparison between the flat plate and tubular batteries.
SMF (Sealed Maintenance Free) batteries:
As the name suggests, such batteries are sealed and don’t require maintenance at all. These batteries are used in numerous vital places like UPS, telecommunications systems, offices automation equipment, fire alarm & security system, railways signals, medical portable devices and vehicles etc.
Exide Industries Ltd is the largest manufacturer of SMF batteries since 1998 with technical collaboration of the Japanese company Shin-Kobe Electric Machinery Co, the manufacturer of Hitachi batteries.
Some notable features and their benefits of SMF batteries are as follows.
- No need to inspect electrolyte level regularly because it contains immobilised electrolytes. Therefore, unlike lead-acid batteries, you don’t need to refill the distilled water throughout the lifespan of the battery.
- The SMF batteries are completely sealed, meaning there is no chance of leakage, therefore, such batteries are considered safest as compared to other batteries. That’s why it can be used at sensitive places.
- The Sealed construction along with immobilised electrolytes allow the battery to place at any position, whether horizontal, vertical, sideways etc without affecting the efficiency of the battery.
- However, the SMF batteries are more costly than the lead-acid batteries.
Warranty Types:
The second important parameter is the warranty offered by various battery manufacturers. I don’t mean that you should buy the battery which offers a longer warranty period. Instead, you should check what types of warranty the company provides, however, it may vary from 3 to 5 years.
Hence, let me explain the types of warranty offered for lead-acid batteries. Though there are basically two types of warranty offered by most of the manufacturers.
Free of Replacement (FOC):
As the name suggests, such types of warranty provide free replacement if your battery encounters a premature failure or is unable to perform efficiently. For instance, let us assume the company offers a 4 years warranty on a battery and during this time if the battery doesn’t work, you will get a new battery free of cost against the damaged battery.
However, sometimes the companies offer pro-rata types of warranty.
Pro-Rata:
However, in the case of pro-rata, you will have to pay some money to get a replacement of the old battery if your battery fails to perform well.
The payable amount depends upon how long the battery is used or in which year it fails.
For instance, suppose you purchase a battery of 5 years warranty, in the fourth year, the battery failed to perform. In such a case how delayed the battery will stop working, the amount payable to get a replacement will increase accordingly.
However, the company can offer both the warranty (FOC & Pro-rata) simultaneously. For instance, suppose the manufacturer provides a 5 years warranty which is specified as 3 years (FOC) + 2 years (Pro-Rata).
Hope the warranty concept regarding batteries would have been cleared now.
Battery Capacity:
The third major factor is the capacity of the battery. You should choose the appropriate battery capacity according to the expected loads.
You need to understand the concept behind the power/ capacity of a battery.
The battery power measured in Ah (ampere per hour), you would be thinking what does it mean by Ah. That means a 150Ah battery is capable of supplying 150 Amp electric current in one hour.
Let us now understand how to calculate battery backup time. First of all, you need to calculate the expected load as per your home.
For instance, let us assume your requirements are as follows.
- 4 Led bulbs : 4*10 watts = 40 watts
- 2 Fans :2 *80 watts = 160 watts
- 1 TV : 1* 80 watts = 80 watts
- 1 Tube light : 1* 20 watts = 20 watts
Hence total loads will be 40 + 160 + 80 + 20 = 300 watts.
Now we need to calculate battery discharging current. For that, we need to divide the total load (300 watts) from the battery voltage (12 V).
Thus, 300/ 12 = 25 Amp (battery discharging current).
By means of which, the battery requires to supply 25 Amp electric current to run above devices whose collective load is 300 watts.
Thus to calculate battery backup time we need to divide battery capacity (150 Ah) to battery discharging current (25A).
Hence, 150/ 25 = 6 hrs. However, it is not an exact calculation because we can’t fully (100%) discharge lead-acid batteries.
The maximum discharge level of lead-acid batteries are typically 70-80%, therefore, let us consider 80% in our case.
Finally, total backup time will be 80% off 6 hrs = 4.8 hrs, means 4 hrs, 48 minutes.
Thus you can now calculate the exact backup time of any battery. Hence, you should choose the appropriate capacity of the battery as per your requirements.
Is the battery compatible with your inverter?
You should also be sure whether the battery is compatible with your inverter or not. Although most of the companies produce batteries which are compatible with every inverter.
Nevertheless, there are some rare batteries which can be functions with a specific UPS. Hence you should check it out for sure.
Best Inverter Battery Brands:
The battery loses its power as time progresses. The battery capacity and life depend on a grid design and active materials used. Though there are many companies in India which manufacture inverter batteries, you should always buy branded products.
The most renowned and trustworthy companies which have been designing and manufacturing inverter batteries for decades. Some top brands are Exide Industries, Luminous Batteries, Amaron, Okaya, V-Gard.
Precautions for inverter batteries:
Some precautions are mandatory if you are using lead-acid inverter batteries because they contain chemicals (lead) which is harmful to the environment and humans.
- Never dispose of your damaged battery. Always replace your old battery from your dealer.
- Keep your battery at a well-ventilated place and away from children.
- During charging lead-acid batteries produce oxygen and hydrogen gases which are highly flammable, hence you should place your battery away from sparks or open flame.
- A solution utilised in lead-acid batteries is the composition of sulphuric acid (35%) and water (65%) works as electrolytes. Therefore, avoid direct contact with the solution as it can harm your skin.
- Check the distilled water level regularly and refill it when low for better performance and life.
Frequently Asked Questions for Best Inverter Battery:
Q.1 What does it mean by battery capacity?
The battery capacity is typically measured in ampere per hour (Ah), by means of which, the battery is capable of supplying 150 Ah of current for one hour (if the capacity of battery is 150 Ah).
In simple words, if you have to consume a current of 15 amps, the battery can provide a maximum backup of 10 hrs efficiently. Similarly if the load is 50 amp, it can provide a maximum backup of 3 hrs only. However, any batteries shouldn’t be discharged completely, you can discharge a maximum of 70 to 80% only.
Q.2 What is Pro-rata Warranty?
The Pro-rata Warranties are generally used in case of non-repairable items such as tyres or batteries. Under such types of warranty, if the product fails to perform during the warranty period, the manufacturer replaces the product with a new one at some cost. The cost typically depends upon the time of failure from the date of purchase and the new product again covers the same warranty as well.
For instance, suppose you purchased a battery having a pro-rata warranty of 36 months, if the battery fails during this period, you will be given a new battery at some upfront cost and the same warranty will be applicable to the new one.
Q.3 Can I replace my battery with another manufacturer?
Yes, you can but the voltage and dimension of the battery must be the same, however, the capacity of the battery may be slightly higher or lower. There are many batteries which are interchangeable with other manufacturers. For more details contact your dealer.
Q.4 Can a lead acid battery be recycled?
Yes, the lead acid batteries are recyclable. Most of the components of a lead acid battery are either 100% recyclable or utilised in some or the other ways. For instance, lead is the most recyclable metal in the world, plastic containers and covers can be used during manufacturing of new batteries, Ammonia sulfate is used as fertiliser etc.
Q.5 What are deep cycle batteries?
The deep cycle batteries are designed and developed in such a way that they can be charged or discharged even hundreds of times. Such batteries can be discharged totally as well before ever recharged.
Q.6 What is the main cause of battery failure?
Most prominent reason why a battery fails to perform is under or over-charged or discharged. The charging device might be a reason if it doesn’t supply proper voltage. Hence check regularly your charging device and electrolytes level.
