Comparing tubular lead acid batteries with lithium-ion batteries is the topic to discuss in this blog. Lithium and tubular batteries are both types of power storage Batteries. One has Lead Acid chemistry, and the other has Lithium and other chemicals that make batteries, but they have different advantages and disadvantages.
Lithium batteries have a higher energy density than tubular batteries, especially since they are C1-rated. Tubular lead acid batteries have a lower density and are C20 capacity batteries, clearly distinguishing that lead acid batteries are made for smaller discharge applications or running smaller loads. Lithium batteries are designed for higher discharge loads to run higher loads. https://suvastika.com/lithium-battery-option-in-inverter-ups-solar-pcu/
Tubular batteries seem less expensive when we talk of price without comparing the advantages and disadvantages, but they are costly compared to Lithium batteries. We will discuss the same in this article. So let us assume we have to run the load of 500 Watt on the 12V Inverter/UPS, and the 150 Ah Lithium battery will give the backup time on the Inverter/UPS. On the Tubular Lead Acid 150AH battery, we will get approximately 2.50 hours of backup on a 400-watt load. For the lithium battery, we need 80Ah to get the same backup on a 400Watt load. Now we can compare the price of a Lithium battery 80 AH or 12.8V Lithium battery with the 12V 150 Ah pricing in the market.
The Tubular battery is C20, and Lithium is C1, creating a significant difference in backup time.
If we compare the pricing of these two batteries in India, we realise the price is 20 to 30% higher in the case of lithium batteries, with 80Ah of 12.8 Volts. Still, the advantages of lithium batteries will not be comparable to those of tubular batteries.

The Life of the Lithium battery compared to the Tubular battery: The Life of the Tubular Lead Acid battery is 1/4th of the Lithium Battery as the Lithium battery can give a 3000-cycle life, whereas the Tubular battery has a maximum of 400-500 cycles if we refill the battery water in time. Distilled water is used to top off the battery.
The size of the Tubular Lead Acid battery vs the size of the Lithium battery: The size will also be one-fourth of the Tubular Lead Acid battery.

The weight of the Tubular Vs Lithium battery The 150 AH tubular battery weighs 58 Kg minimum, whereas the Lithium battery is just 11 Kgsof 80 Ah lithium battery.https://suvastika.com/what-is-lithium-inverter-ups/#:~:text=A%20lithium%20inverter%2FUPS%20is%20an%20inverter%2FUPS%2FBESS%20specifically%20designed,Higher%20energy%20density%20Faster%20charging%20Weight%20and%20space-saving
The charging time of Tubular vs the charging time of Lithium battery: This is another factor that makes them utterly different as the Lithium battery can be charged in 2 to 3 hours whereas the Tubular battery takes 12 to 15 hours to charge.
The cost of charging Tubular Vs Lithium battery: The Lithium battery is charged in two steps and, once charged, doesn’t need trickle charging. The Lithium Lead Acid battery will be charged in 4 to 6 stages, which consumes more power. Lastly, the trickle charging maintains the tubular battery’s gravity intact, and the tubular battery’s self-discharge is much higher than the lithium battery’s. So, the Tubular battery gets more electricity for charging, which is a big waste of power and an extra financial burden on the user.
Lithium has built-in BMS, so it will minutely control all the parameters in Lithium.
The construction of a Tubular battery is unregulated compared to the structure of a Lithium battery cell. No two batteries can match in backup time in the case of Tubular Lead Acid batteries as the construction of each cell can’t be matched, whereas the Lithium is controlled. All the cells are sorted before the battery is made, and equal cell voltage cells are separated by measuring the IR values so that the battery does not have a mismatch in the cell’s IR value.
Maintenance of Tubular Vs Lithium battery: The maintenance of Tubular batteries for refilling battery water is a big headache. The timing of refilling can’t be measured beforehand, so generally, users forget to refill the water in time after refilling the Tubular battery; another major challenge is spillage, which could destroy the floor, which happens in most households and offices.
The Abuse of Lithium Vs Tubular Battery: The Lithium battery has a built-in BMS called Battery Management System, which handles charging and discharging over voltage and under voltage of the battery pack. Hence, no abuse is possible as the BMS very well protects it. Whereas there is no such protection in the Tubular Lead Acid battery, all such conditions can happen and shorten the Tubular battery’s Life.
The explosion of Tubular is a common problem, and the Lithium LifePo4 technology has a safety history: there have been numerous instances where the Tubular batteries have blasted. People got killed, and the Lithium battery, especially LifePO4, has been the safest in the world, and no such significant accidents have occurred so far.
Repair of Tubular Lead Acid Battery compares to Lithium battery pack: The Tubular battery once declared dead or overcharged or one cell fails, then that battery goes for the waste selling whereas the Lithium battery can be repaired very quickly as one cell or two cells can be replaced easily in the Lithium battery pack.
Pollution by the Tubular batteries: Tubular Lead batteries create pollution by emitting Lead fumes, which are very dangerous for people in the vicinity. Lithium has no such challenge. It’s completely safe, as everyone has used lithium batteries in their mobile phones, laptops, etc., for two decades. https://suvastika.com/lead-acid-battery-health-hazards-in-inverter-ups-industry/
Applications
Lithium batteries are well-suited for all kinds of applications as they are small and can be placed anywhere. Tubular lead acid batteries have many limitations in size, weight, maintenance, and Life. Applications with limited space, such as electric vehicles, mobile phones, Laptops, medical equipment, etc. or Inverter/UPS and solar power systems. They are also a good choice for applications where long lifespans and fast charging are essential.
Tubular batteries are a good choice for applications where cost is a significant factor, such as in UPS systems. They are also a good choice for applications where deep discharges are common.
Which battery is right for you? https://www.cummins.com/news/2019/06/17/spot-difference-lithium-ion-versus-lead-acid-battery-electric-technology
The best battery for you will depend on your specific needs and application. Lithium is a good choice for its high energy density, long lifespan, and fast-charging battery. A tubular battery is a good choice if you want a less expensive battery for smaller applications.
The best way to decide which battery is correct is to consult a battery expert. They can help you assess your needs and recommend the best battery for your application, Lithium Battery, compared to a Tubular battery. It is not comparable in terms of all these parameters discussed above.
In the end, the Conclusion is that the Lithium battery is Cheaper than the Tubular Lead Acid Battery.
