Your Ultimate Tubular Battery Buying Guide

Tubular batteries are excellent when it comes to providing consistent power backup during long and frequent power cuts and therefore, it’s the ideal choice if you happen to live in areas that lie on the city outskirts or in tier 2 and tier 3 cities where constant electricity connectivity is still not reliable. 

But, before you head out and buy one, there are few things that you need to be aware of before purchasing that would help you choose the ideal battery for your conditions and provide consistent power backup when you need it the most. 

What is a tubular battery?

tubular battery is similar to other lead-acid batteries and is made of positive and negative plates. A tubular battery is called so due to the shape of the positive plates which have a tubular geometric structure while the negative plates are designed to be flat. The tubular shape of the positive plates provides additional support to the active chemical components within the battery and thus it’s called a tubular battery. 

What are the visible components in a tubular battery?

A tubular battery essentially consists of two visible components:

Structure: This carries the electrical energy that’s generated from the plates and is responsible for holding other active components in the battery.

Reactive Chemicals: This is where the electric energy is generated. A support structure around the reactive chemicals acts as a holder to ensure that the chemicals stay at their place throughout the service life of the battery. 

What Makes a Tubular Battery a Great Choice?

A tubular battery has a robust design which makes it last anywhere between 5 to 8 years.  It provides consistent backup during long and frequent power cuts and can withstand heavier loads when running heavy-duty appliances such as Air Conditioners, Geysers, etc. making it a great choice for larger homes, shops, and commercial establishments where the load is higher. 

Features of a tubular battery:

  • Excellent performance in areas with high temperatures
  • Able to support heavier loads
  • Corrosion-resistant with extremely high purity for extended service life guarantee
  • Low maintenance
  • Great for areas plagued by long power cuts
