Everything You Need To Know About Tubular Batteries

What are tubular batteries?
Tubular batteries are also known as deep discharge batteries is a lead-acid battery. They provide a small amount of current, for example, 5 Amperes, for a long period of time. The electrodes of these batteries are thicker than the regular ones and hence cannot release a large amount of current. Moreover, they cannot be used in domains where a large amount of current is required in a relatively short period of time. Although they don’t provide high current, they last for a longer duration as compared to regular flat plate batteries.


Nantech Power Systems provide a multitude of tubular batteries:

As there are several options, we have provided a brief yet comprehensive comparison of different tubular batteries that you can choose from.

Exide SF Sonic Luminous Rocket Okaya
Plate size The tubular plates are thick in nature. The plates in SF sonic are constructed to be wide and thick. The luminous tubular range of batteries is designed with thick tubular plates. Positive plates are used with low antimony alloy. Okaya batteries are designed with thick and strong plates that extend the working life of the battery.
Climatic conditions Can be operated in extreme climatic conditions. Designed to work in hot and humid weather conditions. Designed to work in hot and humid weather conditions. Designed to work in extremely hot and cold climatic conditions. This zero-maintenance battery can be used in areas where the temperature is warm and humid.
