[Short] tubular vs tall tubular battery

Updated: Apr 30, 2023

Theoretically, the power store in a tall tubular and a [short] tubular battery of identical rating is the same. But the performance of a tall tubular battery is better than a short tubular battery. Here, the performance of a battery can be improved by improving the design of the battery. And the design can be improved in many ways by improving electrode design, increasing the electrolyte volume and improving the electrolyte solutions.


Hence the difference between short tubular and tall tubular batteries is a difference in the design of the battery that improves the performance of the tall tubular battery.


Besides, the difference in performance there are lots of similarities between them too. Both tall tubular and short tubular batteries are the family members of lead-acid batteries. They both have the same electrolyte solution and have the same electrode design. They both have wet electrolytes and hence can also be called wet lead-acid batteries.



Moreover in this blog, I will tell you the difference between these two batteries and how the performance of tall tubular batteries is improved.

Tall tubular Vs [short] Tubular battery

Tall tubular batteries carry 30% more electrolytes and have longer electrodes length than a short tubular, hence taller in size too. Due to these enhancements, they have better electrical and thermal properties than [short] tubular batteries. Hence provides more discharge capacity and needs less maintenance.


An increase in the volume of electrolytes improves the performance of the lead-acid batteries by increasing the discharge capacity between 5% and 20% depending on the discharge current.


Hence the discharge capacity of a tall tubular battery is 5% to 20% more than tubular batteries depending upon the discharge current. Lower the discharge rate higher will be the discharge capacity.

How thermal characteristics affect the performance of the battery.

The battery uses chemical reactions to produce electricity and they use electricity to reverse this chemical reaction. However, electricity isn’t the only that they produce during the discharging process.



Batteries also produce heat during discharging as well as the charging process. In fact, they produce more heat during charging than discharging.

Batteries also produce heat during discharging as well as the charging process. In fact, they produce more heat during charging than discharging.

The more heat battery produces during charging the more electricity it will consume. Similarly, the more heat battery produces during discharging the less electricity it will produce.


Since tall tubular batteries produce less heat while charging and discharging due to high electrolyte volume and taller tubular-shaped electrodes. It consumes less electricity to get charged and produces more electricity as compared to a [short] tubular battery.



Also due to less heat production, tall-tubular batteries required less maintenance because their electrolyte loses less water as compared to any other battery type.


Further let’s compare [short] tubular and tall tubular batteries on the basis of dimension, warranty and price. For a fair comparison, We have considered a 150Ah battery.

Dimension ([Short] tubular Vs Tall tubular battery)

The dimension of a Luminous Red Charge RC 18000 150 Ah tall tubular battery is (L x W x H): 502mm x 191mm x 440mm. And the dimension of a Luminous Red Charge RC 18000ST 150 Ah tubular battery is (L x W x H):505mm x 220mm x 308 mm.


When your compare both dimensions, you will find that tubular batteries are shorter but litter wider than tall tubular batteries. Hence also called short tubular batteries.



Weight ([Short] tubular Vs Tall tubular battery)

The weight of a Luminous Red Charge RC 18000 150 Ah tall tubular battery is 53.3-kilogram and it is heavier as compared to the 42.3-kilogram weight of a Luminous Red Charge RC 18000ST 150 Ah tubular battery.


Warranty ([Short] Short tubular Vs Tall tubular battery)


But there is another luminous make 150Ah tall tubular battery [Luminous Shakti Charge SC18054] whose warranty period is 54 months. And the reason why its warranty period is higher than Luminus Red charge 150Ah tall tubular battery is that it has 47% higher electrolyte volume. Hence it is 11.7% more expensive too.



Price ([Short] Short tubular Vs Tall tubular battery)

Due to higher electrolyte volume, taller electrodes and better performance tall-tubular batteries are more expensive than tubular batteries too.

Conclusion:

From all the above discussion, it is clear that tall-tubular batteries are better than tubular batteries. But that doesn’t mean buying tall-tubular is a win-win condition because they are expensive too. However, choosing between tubular and tall tubular is depends on one thing.


That is the number of the charge cycle you need: One charge cycle is equal to a one-time discharge than charging of the battery. So, if your regions have daily long power cuts or you have an off-grid solar grid then tall-tubular is the right battery you need.


However, if your region has lower power cuts then you should go with a tubular battery.

Here is our recommendation for tall tubular batteries:

Luminous Red Charge RC 25000 200 Ah: Comes with 36 months of warranty, one of the best sellers of Luminous. Highly recommended for off-grid solar power plants.


Luminous Red Charge RC 18000 150 Ah Tall Tubular: Comes with 36 months of Warranty, a best seller on Amazon


Luminous Shakti Charge SC18054 150Ah Tall Tubular: Comes with 54 Months of Warranty 11.7% more expensive than Luminous RC18000 150Ah and has 47% Electrolyte higher volume. Higher electrolyte volume gives it better charge and discharge property and makes it more rigid than Luminous RC18000 150Ah and hence comes with an extra warranty period.


Luminous LPTT12100H 100Ah: Comes with 60 months of warranty, highly recommend for small [200 watts to 500 watts] off-grid solar power plants.


And here is our recommendation for short tubular batteries:

LUMINOUS RedCharge RC 18000 ST 150AH Short Tubular: Comes with 36 months of warranty and is 8% cheaper than its tall-tubular counterpart.


Luminous Red Charge RC 15000 120 Ah: Comes with 36 months of warranty and only 1000 INR cheaper than 150Ah short tubular battery
