Understanding an inverter battery

Batteries are the power source of an inverter. A good inverter or a UPS system largely depends upon a reliable battery to give out the uninterrupted power supply for a few hours. It is thus important to understand the objectives of a good battery to ensure a longer life span of your inverter. Batteries basically come in three different categories:

1. Lead-Acid Batteries

Also known as flat plate battery, these mainly work on lead electrodes and sulphuric acid.  Lead-Acid batteries are the most common type of batteries available in the market and are used in inverters. They are very economical and light in weight. These batteries are easily rechargeable and hold a high capacity of producing current. However, the battery requires regular maintenance to last 3-4 years. Mineral-free distilled water needs to be replenished at regular intervals of time to maintain battery health. Electrolytes need to be kept in check regularly. The batteries also produce toxic gases during the processes of charging and discharging. Thus, it is highly important to place them in an area that has good ventilation.

2. Maintenance free Batteries

Maintenance free batteries are basically sealed batteries or deep-cycle batteries that do not require water top ups and electrolytes check. Built using gel and an absorbent glass mat, these batteries are more expensive and have a shorter life span when compared to the other batteries. The battery excels in providing safety as it does not spew any harmful gases. If one does not mind spending a few extra rupees, these maintenance free batteries are the best bet for people who do not have time to spare or to those concerned about safety.

3. Tubular Batteries

The most reliable and highly efficient battery available in the market for an inverter is the advanced tubular battery. The positive plate of the battery is replaced by a tube for higher efficiency and long operational life (5-8 years). The complex design of the battery adds to its efficiency and low maintenance feature. The only downside to this popular kind is its price tag. They are expensive.

As mentioned earlier, the shelf life of an inverter depends upon the battery. It is highly advisable to choose the right battery with a good company backup instead of local ones. Choose a battery with the right capacity to get the maximum backup for your home. This can be achieved by calculating the capacity based on the power requirement and the duration of the backup required. Use this simple formula to calculate the battery capacity.

Battery capacity = (power requirement in watts) X (backup duration in hours)/ voltage

Power requirement depends upon the number of gadgets and appliances you want to light up during the power cuts. For example, a fan takes 75 watts while a lamp takes 40 watts. Considering you need an inverter to light 3 bulbs and 2 fans, 3*40+2*75= 270 watts. The backup duration depends on how long you want the inverter to run during power cuts. This decides the size of the battery. Lastly, the nominal voltage in a battery cell is always 12V.

Things to consider before buying an inverter battery

1. Check the VA rating of the inverter

The VA rating of an inverter basically denotes its capacity. It is essential to know the inverter capacity to buy a battery that supports it. It is often measured using Volt-Ampere. The VA rating of an inverter denotes the voltage and current supplied by it to the required appliances. It is necessary that your inverter capacity matches the total power requirement.

2. Be mindful of your inverter-battery compatibility

Now that it is clear that the battery-inverter compatibility is very important for an efficient service, do check it before buying either of them. Calculate the inverter capacity as well the battery capacity to see if they work well together. The size of the battery is crucial for an inverter to work for long periods of time without any hindrance.

3. Battery Voltage

Although most of the appliances require 12V of battery voltage to run efficiently, it does no harm to know other variations available in the market. Irrespective of the type of battery you use, the nominal voltage of 12V is required for home inverters. Top brand manufacturers produce batteries of 24 and 48V as well but unfortunately, they are not available in India. A 12V battery works just fine to source electricity for long hours.

4. Sourcing larger appliances  

Inductive loads such as televisions, refrigerators, and air conditioners resist the change in the current which can result in short circuits and lagging. The motors in their compressors need a larger amount of power supply in order to run the appliance effectively. Thus, if you are sure of the need for such larger appliances, you might have to consider buying an inverter and battery of higher capacity.

5. Long power cuts and fluctuations

The efficiency of an inverter and battery is best tested during long power cuts. Especially in countries like India where frequent power cuts are addressed, the need to buy the right battery takes priority. The duration of the backup required is directly proportional to the size of the battery. Keep the required duration in mind before looking for a good battery. The higher the Ampere hours of the battery, the longer is the backup provided. If voltage fluctuations are one of your major concerns, consider buying a tubular battery.

6. Brand Quality

Brand quality plays an important role in deciding the investment and efficiency of the battery. Stay clear of the local products to protect your inverter from getting damaged. Choose an ISI marked product to get the benefit of low service cost. Brands provide the guarantee, warranty, and good customer service and support. Do not be fooled by new brand names and models. Opt for trusted brands such as Exide, Luminous and Amaron.

7. Area of Installation

However insignificant it may sound, choosing the right installation area requires special attention. Especially, if you decide on buying a lead-acid battery! These batteries need to be placed in a good ventilated space as they are prone to producing toxic fumes during their charging and discharging processes.

8. Warranty

Generally, warranty comes in two phases for the inverter batteries. One is the FOC- free replacement warranty that usually extends up to 3 years. In case of any damage to the tiniest of the component, under the FOC warranty, it can be replaced free of cost. Another advantage of buying a branded battery! The validity of the warranty period represents the quality of the product. Along with the replacement warranty, brands often give out an extended warranty for up to 12 months. This pro-rata warranty allows you to save some money if you have to replace the battery out of the warranty period.

Mistakes to avoid while handling an inverter battery

  • Undercharging/Overcharging

Consistently using the battery in a partially charged state or not allowing the battery to recharge completely after its use leads to the diminution of its performance. Allowing the battery to rest in its discharged state for a prolonged time period, results in the sulfation of lead and stratification. Similarly, overcharging of the battery may also cause premature failure. Constant charging causes corrosion of the positive plates. It also leads to high water consumption and irregularities in maintaining acid temperature. The batteries should be charged after consuming 50% of its stored energy.

  • Underwatering/Overwatering

It is important to keep a check on the electrolyte level to maintain battery health. Water replenishment in the batteries depends on the type of battery used. For example, tubular batteries require water topping only once a year whereas deep-cycle batteries and lead-acid batteries require topping every 3-4 months. It is essential to keep in mind that overwatering or underwatering the batteries can cause irreparable damage. Water is basically consumed during the charging process. Excessive watering ahead of charging will result in an increase in the dilution of electrolytes or in electrolyte overflow.

  • Temperature check while charging

Tubular batteries are made to withstand extreme weather conditions. But if you have opted for a lead-acid battery, maintaining the temperature of the battery while charging should be your top priority. Make sure the temperature doesn’t reach 52℃ sporadically. If something like that occurs, it is advisable to discontinue the charging process and allow the battery to return to its normal temperature.

  • How to check the battery performance

If you need to check how well your battery is performing after a certain period of time, allow a fully charged battery to stand an open circuit for an hour. Now, measure the voltage. A 12V battery should not exceed 0.30. If it does, then it may indicate a problem. Further, it is checked using a hydrometer to see the electrolyte specific gravity readings which again should not exceed 30 points.
