Lithium Batteries are Now Cheaper than Tubular Batteries. This article will discuss this topic and explain the difference between Lithium and tubular batteries.
Lead-acid-based Tubular and lithium batteries are two of the most common types today, competing for large power storage solutions for homes, offices and other projects.
They have different advantages and disadvantages, so the best type of battery for you will depend on your specific needs.
The Benefits of Replacing Gensets with Lithium-based Battery ESS
Lead-acid Tubular batteries are typically less expensive than lithium batteries.
However, the cost of lithium batteries has been declining in recent years, and they are becoming more affordable.
The lead acid tubular battery comes with a C20 capacity, and the Lithium Battery comes with a C1 or C3 capacity.
So, there is no match between lead acid and lithium batteries as per capacity at the discharge level.
Backup of Lithium and Tubular Battery
A Tubular Lead Acid battery is the most acceptable in Inverter, UPS and solar System applications.
So, it’s imperative to compare these two technologies and give the proper perspective to the consumer.
So, to run a higher load, like 1000 watts for a 12-volt inverter/UPS or solar PCU application, it draws 83 Amps from the lead acid battery.
Hence, the 200Ah Tubular battery becomes a 60 Ah if the 83 amp current is drawn.
So we need a 70 Ah lithium battery to get more backup compared to a 200 Ah Tubular battery.
So, if we compare the cost of Lithium LifePo4 battery and Tubular lead Acid battery of these two sizes.
We realize the Lithium battery price of 70 Ah is less than the Tubular battery price of 200 Ah.
So we have to compare Lithium batteries vs tubular Lead Acid batteries.https://suvastika.com/difference-between-tubular-and-lithium-battery/
One must understand the backup time calculations done on Peukert’s Law for Lead Acid batteries are obsolete today.
So far, the manufacturers and dealer distributors have not made any chart showing Tubular Lead Acid battery performance at higher Load discharge.https://suvastika.com/new/wp-admin/post.php?post=11358&action=edit&classic-editor=1
Weight and volume
Lead-acid batteries are no comparison as a 150 Ah Tubular battery is 62 kg, and an 80 Ah lithium battery of 12.8 v is not even 10 kg in weight.
Energy density
Lithium batteries have a higher energy density than lead-acid batteries. Lithium batteries can store more energy in a given volume or weight.
Charging time
Lithium batteries can be charged in 2 hours, and Tubular batteries take at least 15 hours to charge completely.
So Lithium batteries can give five times back up in a day if there are intermittent power cuts.
Meanwhile, tubular batteries will not be able to give backups twice a day.
Cycle life
Lithium batteries have four times the life of tubular batteries. The Lithium battery comes with a Digital Warranty of 3 years.
Operating temperature range
Lithium batteries have a narrower operating temperature range than lead-acid batteries. This means that lithium batteries are less tolerant of extreme temperatures.
Safety
Lead-acid batteries are less safe than lithium batteries. This is because lead-acid batteries can release lead fumes when charged or discharged for any home or office, which should be avoided as Lead has been banned in most areas.
We have kept the provision in our few models for Tubular and Lithium LifePO4 batteries. The user can select which battery to install as per his knowledge and understanding.
Tubular batteries vs lithium Batteries
Maintenance: The tubular lead acid battery needs distilled water topping once every 3 to 6 months, which is a big headache for the user, as it is hard to get the distilled water and refill it in time. After the refill, the acid comes out on the floor, which destroys the marble floor.
Overall
Lithium batteries have several advantages over lead-acid batteries, including higher energy density, longer cycle life, and faster charging time. However, lithium batteries are also more expensive and have a narrower operating temperature range. The best type of battery for you will depend on your specific needs and budget.
Here are some additional considerations when choosing between lead-acid and Lithium batteries:
- Application: If you need a battery for a high-performance application, such as to run higher loads like fridges, geysers Airconditioners, Laser printers, CNC Machinery, microwave ovens, Coffee machines, etc., then Lithium is the right choice, but if you want to run small loads of house like fans LEd lights and TV etc. than the Lead Acid can be a choice but refilling the water and space taken is a big challenge.
- Price Point: if one sees all these benefits and comparisons, one can realize that a Lithium battery LifePO4 is cheaper than a Tubular lead Acid battery.
- Operating environment: A lithium battery is a better choice if you live in an area with extreme temperatures. Lead-acid batteries are not as tolerant of extreme temperatures. They need ATC features in the UPS.https://pallavaggarwal.in/2023/06/29/lithium-battery-vs-tubular-battery/
