Lead-acid and lithium battery are two of the most common types of battery today.
They have various advantages and disadvantages, so the best type of battery for you will depend on your specific needs.
Lead-acid 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 battery comes with a C20 capacity, and Lithium Battery comes with a C1 or C3 capacity. So there is no match between Lead Acid and Lithium battery as per capacity at discharge level.
As Tubular Lead Acid battery is the most acceptable battery in Inverter, UPS and solar System applications. So it’s imperative to compare these two technologies and give the proper perspective to the consumer.
To run the higher load, like 1000 Watt for 12-volt Inverter/UPS or solar PCU application, draws 83 Amp from the lead Acid battery. Hence, the 200Ah Tubular battery becomes a 60 Ah battery, if the 83 amp current is drawn.
We just need 70 Ah lithium battery to get the more back up compare to 200 Ah Tubular battery.
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 lesser than Tubular battery price of 200 Ah
Lets compare Lithium battery Vs Tubular Lead Acid battery.
One must understand the backup time calculations done on Peukert’s Law for Lead Acid batteries is obsolete today.
So far, the manufacturers and dealer distributors have not made any chart that Tubular Lead Acid battery performance at higher Loads discharge.
Weight and volume
Lead-acid batteries are no comparison as a 200 Ah Tubular battery is 60 kg and a 70 Ah lithium battery of 12.8 v is not even 6 kg in weight.
Lithium batteries have a higher energy density than lead-acid batteries. Lithium batteries can store more energy in a given volume or weight.
Lithium batteries can be charged in 2 hours, and Tubular batteries take a minimum of 15 hours to be completely charged.
So Lithium batteries can give five times back up in a day if there are intermittent power cuts.
Where as the tubular batteries will not be able to give two times back up in a day.
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.
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 Baterries
Maintenance Tubular lead acid battery needs distilled water topping once in 3 to 6 months, which is such a big headache for the user to get the distilled water and refill in time. After the refill, the acid comes out on the floor, which destroys the marble floor also.
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 Air conditioners, Laser printers, CNC Machinery, microwave ovens, Coffee machines etc., 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.
