An inverter is a device every household utilises as a power backup, in case of electricity shortage. The core component of an inverter is the battery; it is the very backbone. Most often, it is the battery of any inverter that significantly affects:

  • Life

  • Power

  • Performance

At present, there are three types of batteries that are employed in inverters, commonly, – lead acid, maintenance free and tubular batteries.

Type of Batteries & Their Features

  • The frequently wielded inverter batteries are Lead Acid because they are

  1. Rechargeable
  2. Lightweight
  3. Economical

Lead acid batteries create massive amounts of current and have a lifetime of 4 years. But they do consist of some drawbacks:

  1. Need consistent maintenance
  2. Electrolytes have to be topped up periodically
  3. Give out noxious gases when charging
  4. Require installation in ventilated areas
  • The second type of battery is an improved version of lead-acid models called maintenance free batteries. They are so termed because they are sealed and do not require electrolyte top-ups regularly. Such inverter batteries are:
  1. Safer than lead acid
  2. Short-lived when compared to others
  3. Heavier on the pocket

But once installed, there is no worrying about servicing them every few months. They come under the fit-and-forget category.

  • The third battery type – tubular – is widely prevalent because they are the most efficient. Designed with an intricate pattern, the battery requires almost no maintenance and yet have an operational life of nearly two decades. Their only disadvantage is cost, and that is offset by the value they provide.

Tips To Increasing Battery Lives

Like every other technology on the planet, each inverter battery has its pros and cons. No matter which kind of battery is selected, ranging from an excellent Microtek inverter to a local, cheap one, there is an end date to them all. But when proper care is taken, and the batteries kept healthy, the lifespan can be augmented. Elucidated beneath are some guidelines for their care.

  • The two fatal diseases for batteries are rust and corrosion. Both of them restrict the flow of power in and out of the battery. A reduced flow is equal to slower charging which affects the life of the battery and the backup it provides. Therefore, always ensure there is no rusting. A simple method of removing corrosion is:
  1. Make a solution of hot water and baking soda.
  2. Pour it over the terminals.
  3. Use a soft toothbrush to remove the corrosion gently.
  4. Apply a coat of petroleum jelly to the terminal after the rust is removed.

Use the jelly on nuts and bolts to prevent further corrosion.

  • Proper charging of batteries is crucial to their age. Once installed, they have to be utilised regularly. If there are no power cuts, it is advised to discharge the battery every 30 days completely followed by recharging.
  • Every 60 days inspect the water level in the battery. It should be somewhere between the minimum and maximum boundary. If the water level is low, top it up with distilled water only. On no account, pour normal tap water. It contains minerals that adversely affect the life expectancy and impurities that lower performance.
  • With the passage of time, the capacity of every battery plunges. Better quality inverters do last longer, have the right storage capacity but still wear out as they age. The tip is to switch out the battery of the inverter once they wear out.

Escalating The Battery Capacity

Maintenance and care can keep a battery operational for longer, just as is the case for every house appliance. But there are some tricks that can extend the backup capacity of inverters too.

  1. Remove all extraneous loads from the battery. The energy stored in a battery powers the devices and electrical gadgets in a home. The more the number of appliances connected to a battery, the bigger the load it bears. Therefore, the amount of power it gives off is higher. When only a few essential electronics are linked to the battery, a small amount of energy is sucked out of it, and thus, the backup capacity is extended.
  2. Switch out the fixtures and appliances in the home with energy saving options. A standard bulb requires 75% more electricity to give the same amount of light as a CFL. A fan that has low quality and poor copper winding need more power to run at the same speed as a better copper wire model. When energy-efficient devices are utilised in a residence, the consumption of inverter battery decreases and backup period rises.

Crucial Last Few Recommendations

A tool is as useful as its making. A shoddily created knife will not chop a vegetable correctly. Similarly, a poor-quality battery will not be a great backup during power cuts no matter how well it is maintained. Therefore, always select a well-known inverter which employs a sealed, maintenance-free battery. If possible, then choose lithium battery inverters.
