New 3.2KWh Lithium Battery Challenges Tubular Lead Acid Battery

3.2KWh Lithium battery with Lithium Inverter

A 3.2 kW lithium battery for Inverter is a battery that has a capacity of 3.2 kilowatt-hours (kWh). This means it can store 3200 watts of electricity for one hour. A new 3.2KWh Lithium Battery Challenges Tubular Lead Acid Battery doubles its Tubular Lead Acid battery’s capacity. Lithium batteries are a good choice for inverters because they are lightweight, have a long lifespan, and can be discharged deeply without damage.

The comparison with Lead Acid Batteries with 3.2 KW can be made as 4 Tubular Lead Acid Batteries of 150Ah having C20 capacity will be able to give less backup compared to 3.2 KW load if you put 3 KW or more load on 4 Tubular Baterries as the Tubular Lead Acid battery of C20 capacity is not made for high wattage or High Current discharge. Hence, it cannot stand the high wattage discharge to give efficiency. As the discharge current or wattage increases on the tubular lead acid battery, its efficiency starts reducing. So, at the 50% rated discharge, the capacity of C20 goes below  40% of its rated capacity. So running high in rush appliances like Air conditioners, motor pumps, etc., is not easy on the Tubular Lead Acid batteries.

Here are some of the benefits of using a 3.2 kW lithium battery for Inverter:

  • High energy density: Lithium batteries have a high energy density, meaning they can store much energy in a small, lightweight package. This makes them ideal for inverters, which need energy storage for power appliances and other devices. The Lithium battery has a capacity of C1 compared to the Tubular Lead Acid battery, which is C20 used in the Inverter industry. So, the 80 Ah Lithium battery has more power than the 150 tubular battery.

  • Long lifespan: Lithium batteries have a long lifespan, with some models lasting up to 10 years. This means you won’t have to replace your battery as often, saving you money in the long run. The life of the tubular Lead Acid battery is generally 2 to 3 years, during which the capacity decreases drastically.

  • Deep discharge capability: Lithium batteries can be discharged deeply without damaging them. This means you can use more of the stored energy in your battery before recharging it. Because the tubular Lead Acid battery is of C20 capacity and the Lithium comes in C1 capacity, it makes a lot of difference in capacity terms as half the capacity of the Tubular Lead Acid battery Lithium battery has more backup on higher load. So, a 150 Ah Tubular battery has a lesser capacity if we put the 500 Watt load on it than an 80 Ah Lithium battery of the same voltage.

  • No maintenance: Lithium batteries require no maintenance at all, and You don’t need to refill the battery water regularly, which is required for tubular lead acid batteries.

  • No Pollution: The Tubular Lead Acid battery creates a lot of pollution in the vicinity as it produces Lead fumes while charging and discharging the battery. The Lithium battery causes no pollution as it’s a completely safe and sealed battery.
  • Heavy Loads: Running heavy loads like air conditioners, motor pumps, etc., is difficult on the tubular battery. The lithium battery can run two air conditioners simultaneously if the air conditioner is in the 5-star category. It has a C1 rating so that it can run heavy loads like motors and pumps, etc., very easily.
  • Costing: The cost of a Lithium battery will be almost the same as that of 4 Tubular batteries, which will not last more than three years, and the capacity will be lost in these three years. So, the Lithium battery is cheaper than the Tubular Lead Acid battery.
  • Solar Application: In the Solar hybrid or off-grid system, the Tubular Lead Acid battery is not successful at all as the Tubular battery can be charged by 10% of its rated capacity only, so by a solar system, one can charge in 10 hours only whereas the Lithium battery of 3.2KWh can be charged in 2 hours and hence can be charged in two hours with the high capacity solar charge controller. Another major factor is life, three times that of the tubular lead acid battery, so that the solar running cost will be much cheaper than the tubular battery.
  • Size of the Lithium Inverter: The Lithium battery having 3.2KW capacity can be used with the 5KVA Lithium Inverter or with the Solar hybrid Inverter with the capacity of 5KVA very easily as it can take the load of 4KW very easily. While running the tubular batteries, the running load of 4 KW means the backup time is reduced to 25 minutes or less than in case one uses four 150Ah tubular batteries. The backup in the lithium battery case will take 45 minutes if we load it with a 4 KW. The life of the Tubular battery will be drastically affected, and a topping of water will be more if we draw higher current from the Tubular batteries.

If you are looking for a reliable and efficient battery for your Inverter, a 3.2 kW lithium battery is a great option.
