2.4 KW Lithium Battery vs Tubular Lead Acid Battery: A Comparison

2.4 KW Lithium Battery vs Tubular Lead Acid Battery: A Comparison

A 2.4 KW lithium battery can be compared with two tubular batteries of 150 or 200 Ah capacity. So, the 2.4KW Lithium battery will provide higher backup than the Tubular Lead Acid batteries of 150Ah or 200Ah, having a C20 capacity of two numbers. So having a 24Volt or Solar Inverter System with a 200 Ah bank of two batteries will give less backup compared to the 2.4KW Lithium battery bank size of LifePO4 or any other Chemistry. The cost of two Tubular Lead Acid batteries will be approximately Rs 26,000, and the cost of a Lithium battery of 2.4 KW price will be around Rs 30,000/ or around RS 32,000/ which has a higher backup time compared to the backup time of two Tubular Lead Acid batteries of 200Ah capacity. If we compare these two batteries’ prices, the Lithium battery will be cheaper than the Tubular battery in terms of backup time, Life, maintenance, size and weight.

• Advantages:
  • High energy density: Lithium batteries have a higher energy density than tubular batteries, which can store more energy in a smaller, lighter package. Especially in the Solar Hybrid System, the size matters a lot as the space is very limited, and this battery can be installed with the Solar Inverter in a smaller space.
  • Long lifespan: Lithium batteries have a much longer lifespan than tubular Lead Acid batteries, typically lasting 7-10 years or more, as the tubular battery hardly lasts for three years. Especially in Solar Hybrid Systems, the tubular battery’s life is further reduced. The cycle life of tubular lead acid batteries is 500, while the Lithiunm LifePO4 battery has around 2000 cycles, creating a major difference. The life cycle of a tubular lead acid battery will depend on its maintenance, like refilling the battery water in time, which is the biggest challenge in maintaining the tubular battery. Meanwhile, the lithium battery requires no such maintenance.
  • Fast charging: Lithium batteries can be much faster than tubular batteries, typically in 2-3 hours. For the Solar application, the timings are very important as the Tubular battery takes 12 to 15 hours to charge properly as it needs to charge in 3 stages minimum. Some people install a higher capacity solar charge controller to install more solar panels in the Solar PCU, which charges the Lead Acid battery very fast. The Tubular battery needs more watering, and the batteries also explode in case of fast charging. Lithium batteries can be charged in 2 hours and installed with more solar panels.
  • Deep discharge tolerance: Lithium batteries can be discharged much deeper than tubular batteries without damaging them.
  • Low self-discharge rate: Lithium batteries are very low, meaning they can hold their charge for much longer when unused.
• Disadvantages:
  • Charger Parameters: Lithium batteries require a very different charger than the Tubular Lead Acid battery charger, and the charger designed for the Lithium battery will only make the life of the Lithium battery; otherwise, the life of the Lithium battery will be affected.
  • Narrower operating temperature range: Lithium batteries have a narrower operating temperature range than tubular batteries and may not perform as well in extreme temperatures.

Tubular Battery

• Advantages:
  • Lower upfront cost: Tubular batteries are less expensive to purchase upfront than lithium batteries.
  • Wider operating temperature range: Tubular batteries are wider than lithium batteries and can perform better in extreme temperatures.
• Disadvantages:
  • Lower energy density: Tubular batteries have a lower energy density than lithium batteries, which can store less energy in a larger and heavier package.
  • Shorter lifespan: Tubular batteries have a shorter lifespan than lithium batteries, typically lasting 2-3 years. Especially in solar applications, the life is further reduced.
  • Slower charging: Tubular batteries take longer than lithium batteries, typically 15-20 hours.
  • Less tolerant of deep discharge: Tubular batteries should not be discharged to more than 50% of their capacity, or they will be damaged.
  • A 2.4 KWh lithium battery will be cheaper than the 2 Tubular batteries of 150 Ah.

Overall

Lithium batteries offer several advantages over tubular batteries, including higher energy density, longer lifespan, faster charging, deeper discharge tolerance, and lower self-discharge rate. However, they are also more expensive to purchase upfront. Tubular batteries are less expensive upfront and have a wider operating temperature range. However, they also have a shorter lifespan, slower charging times, and are less tolerant of deep discharge.https://suvastika.com/is-lithium-battery-good-for-inverter-ups/

Which type of battery is right for you will depend on your specific needs and budget. A lithium battery is a good choice if you want a battery with a long lifespan, fast charging times, and deep discharge tolerance. A tubular battery may be a better option if you are on a tighter budget or need a battery that can operate in extreme temperatures.
