Surprising Difference between Tubular batteries and Normal Inverter batteries

Tubular inverter batteries and normal inverter batteries are both types of lead-acid batteries, but they have some key differences.

Structure of Plates

One main difference is the design of the plates inside the battery. Tubular batteries have plates that are made in the form of tubes, while normal batteries have plates that are made in the form of flat sheets. The tubular design allows for more electrolyte to be used, which increases the battery’s capacity and life.


Tubular inverter batteries have a tubular positive plate design, which is more durable and has a longer lifespan compared to normal inverter batteries that have a flat plate design.


Another difference is that tubular batteries are generally more expensive than normal batteries. This is because the tubular design is more complex to manufacture and requires more raw materials.
Tubular batteries also have longer life, typically 10-12 years, which is 2-3 times more than the life of a normal inverter battery. They also have a higher tolerance for deep discharge, and are less affected by temperature variations.


In terms of applications, tubular batteries are mostly used in large-scale and premium inverter systems and for solar power storage. While normal batteries are used in smaller-scale inverter systems and for backup power.

Power Output:

Tubular inverter batteries have a higher power output and can handle more power loads than normal inverter batteries.


Overall, tubular batteries are more expensive than normal batteries, but they offer better performance and longer life, making them a good choice for high-demand applications.
