1.2KW Lithium Battery vs Tubular Battery for Inverter: The Ultimate Guide

1.2 KW Lithium battery can replace 200 Ah Tubular Lead Acid battery in the inverter/Solar Hybrid inverter or Solar PCU application. This article will discuss the pros and cons and provide detailed points about comparing these two batteries. The backup time, if calculated at 400 Watt or more on the 1.2 KW Lithium battery and the Tubular battery with a capacity of 200 Ah 12Volt, the Lithium battery is the clear winner as the tubular Lead Acid battery is c20 capacity and the Lithium is C1 capacity battery. The Lithium battery of 1.2KW will give a capacity of 1200 watts compared to the 200 Ah Tubular Lead Acid battery, which should give 2.4KW output. Still, because of C20 capacity, it’s unable to provide 2400 watts at any given load. At the 1000-watt load, the Lithium battery can give 1 hour and 10 minutes of backup, and the Tubular 200Ah might give 45 to 50 minutes.https://suvastika.com/lithium-battery-compared-to-tubular-battery/

Advantages of Lithium batteries

  • High energy density: Lithium batteries come in 12 Kgs compared to the 65 Kgs of 200 Ah Tubular Lead Acid battery. Suppose we see the size of the one-tenth of the size of the tubular battery.
  • Long lifespan: Lithium batteries have three times the life of the tubular lead Acid battery, which is a very important difference.
  • Fast charging: Lithium batteries can be charged in 2-3 hours, while tubular batteries can take up to 15 hours.
  • Capacity: Lithium battery of 1.2KW has more backup compared to 12V/200Ah Tubular battery of C20 capacity.
  • BMS: The lithium battery comes with the battery Management System, which has complete control of the Lithium battery as the BMS has a lot of functions to perform for the safety and life of the lithium battery, like Equalization of each cell in the battery.
  • Protections: The BMS in the lithium battery has the protection of high- and low-voltage batteries and overload and Short-circuit protection, which keeps the battery alive and protects it from any abuse, which is not possible in the tubular lead acid battery.
  • Maintenance: Lithium batteries do not require as much maintenance as tubular batteries.
  • Cons:
    • High upfront cost: Lithium batteries are more expensive than tubular ones.
    • Narrower operating temperature range: Lithium batteries, as well as tubular batteries, cannot operate in extreme temperatures.
    • Safety concerns: Lithium batteries can be dangerous if not handled properly.

Tubular batteries

  • Pros:
    • Lower upfront cost: Tubular batteries are less expensive than lithium batteries.
    • Wider operating temperature range: Tubular batteries can operate in extreme temperatures better than lithium batteries.
    • More forgiving of overcharging: Tubular batteries are more forgiving than lithium batteries.
    • Exchange Cost: Tubular batteries are used to have better recycling costs, which is also slowly happening in lithium batteries.
  • Cons:
    • Lower energy density: Tubular batteries store less energy than lithium batteries of the same size and weight.
    • Shorter lifespan: Tubular batteries have a 3-5 year lifespan, while lithium batteries can last up to 10 years.
    • Slower charging: Tubular batteries can take up to 15 hours, while lithium batteries can be charged in 2-3 hours.
    • Shallow discharge: Tubular batteries should only be discharged to 50%, while lithium batteries can be discharged to 80% without damaging the battery.
    • More maintenance: Tubular batteries require more maintenance than lithium batteries.

Which battery type is right for you?

Your best battery type 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, and deep discharge capability. However, a tubular battery may be a better option if you are on a budget or need a battery that can operate in extreme temperatures.https://suvastika.com/is-lithium-battery-good-for-inverter-ups/

Here is a table that summarizes the key differences between lithium batteries and tubular batteries:
