Benefits of Lithium battery in Inverter/UPS

Lithium batteries, when used with inverters/UPS (Uninterruptible Power Supply), offer several benefits compared to traditional lead-acid batteries. Benefits of Lithium battery in Inverter/UPS:

  1. High energy density: Lithium batteries have a much higher energy density than lead-acid batteries, which means they can store more energy in a smaller, lighter package. This is particularly advantageous in UPS systems where space and weight are critical factors.

  1. Longer lifespan: Lithium batteries generally have a longer lifespan than Tubular lead-acid batteries. They can endure more charge-discharge cycles without significant degradation, leading to a longer operational life.
  2. Faster charging and discharging: Lithium batteries have higher charge and discharge rates, allowing them to charge faster and provide power more efficiently. This is especially useful in UPS systems responding quickly to power outages and fluctuations. The Lithium battery is charged in 2 to 3 hours, whereas the Tubular lead Acid battery takes 15 hours to charge.
  3. IOT feature: the Lithium battery has the Battery Management System to monitor and control its parameters through Bluetooth and Wi-Fi mobile applications.
  4. Lower self-discharge rate: Lithium batteries have a lower rate, meaning they can hold their charge longer when not in use. In contrast, Tubular lead-acid batteries tend to lose charge more rapidly over time.
  5. Smaller size and weight: Lithium batteries can be much smaller and lighter than lead-acid batteries due to their higher energy density. This makes them easier to handle and install in various applications.
  6. Reduced maintenance: Lithium batteries require minimal maintenance compared to Tubular lead-acid batteries, which may need regular checks for water levels and acid replenishment.
  7. Improved efficiency: Lithium batteries have higher charge and discharge efficiency, meaning less energy is wasted during charging and discharging. This leads to better overall system efficiency in Inverter/UPS applications.
  8. Safety features: Many lithium batteries have advanced safety features such as overcharge protection, over-discharge protection, and thermal management systems. The Lithium battery comes with a battery Management System built in where there is no Tubular Lead Acid battery protection system. These features help prevent damage to the battery and ensure safe operation in Inverter/UPS systems.
  9. Scalability: Lithium battery systems can be easily scaled up or down depending on power requirements, making them more flexible for various applications.,Higher%20energy%20density%20Faster%20charging%20Weight%20and%20space-saving

Despite their advantages, it’s essential to note that lithium batteries are generally more expensive than lead-acid batteries up front. However, the overall cost-effectiveness and long-term benefits often outweigh the initial investment, as the life of the lithium battery is four times of the tubular battery. Hence, the Lithium battery is cheaper than the Tubular Lead Acid. battery.

  1. […] Retrofit Lithium-ion battery: At Su-svastika, we have been continuously launching models for retrofitting the old inverters and UPS fitted in the market to replace the lead Acid battery installed with them so that the pollution in the environment reduced and the life of the battery is increased minimum two times compared to the Lead Acid battery. These retrofit Lithium batteries can replace lead acid batteries of any make of Inverter and UPS sold in the market. […]

  2. […] High energy density: Lithium batteries can store significant energy in a relatively small and lightweight package. This makes them ideal for homeowners who want to maximize their solar energy storage capacity without taking up too much space. The Solar Tubular batteries come in a C10 rating, and the lithium batteries come in a C1 capacity. […]

  3. […] Overall, inverters with built-in lithium batteries offer several advantages over traditional inverters with lead-acid batteries. They are a more cost-effective and environmentally friendly option, providing a more reliable and efficient power source. […]

  4. […] To run the 6KW load for one hour on the Inverter, Solar or UPS, we need a 6KW Lithium battery, and if we need to run the same Load on Tubular batteries, then we need eight nos of 200 Ah Tubular batteries of C20 capacity. Suppose we calculate the cost of 8 numbers of 200Ah Tubular battery bank cost. In that case, it will be approximately Rs 100,000/ and if we calculate the cost of the Lithium battery bank of LifePO4, that will be around Rs. 98,000/ so, which will be cheaper than the cost of a tubular Lead Acid battery bank. To keep the eight tubular batteries, we need a steel rack as the weight of each battery will be around 65 Kg. This rack will cost another Rs 5,000/ and the space taken to keep these eight batteries will be another headache. […]

  5. […] addition to these advantages, lithium batteries are becoming more affordable and accessible. As a result, they are becoming increasingly popular in inverter/UPS […]

  6. […] So we have designed the Lithium battery bank with a BMS, a heavy-duty BMS controlled through the MCB and fan to keep that battery cool. There is a buzzer and LED indications to show the status of the Lithium battery, and this is a patented technology by which this Lithium Life PO4-based battery can be installed with any kind of Inverters available in the market. The charging inside the BMS is regulated according to the Lithium battery requirement and can give a life of 10 years. […]
