Lithium Batteries Relationship Between Cycle Life and Service Life

Time: 2021-12-07    Author: nRuiT    Source: This Site    Views: 130

Lithium batteries have become popular for electronic devices because of their high energy density, long-lasting capacity, and lightweight. Lithium batteries, especially lithium-ion, are rechargeable, easy to use, inexpensive, and work on most appliances and gadgets.

The performance, cost, and safety characteristics of lithium batteries vary across types. Handheld electronics mostly use lithium polymer batteries. Lithium iron phosphate, lithium manganese oxide, and lithium nickel, manganese cobalt oxide may offer longer lives, have better rate capability, and are widely used for electric tools, medical equipment, and other applications.

This article will mainly discuss the feature of lithium batteries and the relationship between cycle life and service life.

Features of lithium batteries


Lithium batteries have a long-lasting capacity. They can last for five years or more and provide 80% of the rated capacity after 2,000 cycles. The batteries are less expensive and more potent than other types of batteries.


Quick & Efficient   

Lithium batteries can charge very fast to reduce the downtime and discharge rate. The battery has unparalleled efficiency, especially in high-stress situations. Lithium batteries are the ideal choice for applications that will run in extreme weather.



Compared to other batteries, lithium provides tremendous energy at less than half the weight and size. This means more flexibility, easier installation, and the best choice for mobility equipment. Lithium-ion batteries typically weigh 30% lighter than lead-acid batteries.

Relationship Between Cycle Life and Service Life of  Lithium Batteries

The battery has a finite life, and they degrade gradually over time leading to reduced capacity. Therefore, understanding the relationship between the cycle life and the service life is vitally important for managing batteries performance.

The cycle life of a lithium-ion is the number of charges and discharge cycles completed before losing performance. For instance, the cycle life of lithium-ion batteries is affected by the depth of discharge. A battery discharged by 20% of its total energy capacity has a better cycle life than a battery that is discharged by 80%, which means only 20% of its full energy charge will remain. On the other hand, the service life of a lithium battery is the total life in use from the point of sale up to the point of discard.

The batteries’ cycle life and service life are affected by several stress factors, including temperature, time, charge current, discharge current, and depth of discharge. When the battery reaches its specified lifetime, it does not stop working suddenly.

Battery whose capacity had fallen to 80% after 1000 cycles will probably continue working to perhaps 2000 cycles when its effective capacity has fallen to 60% of its original capacity.

How nRuiT can help you

nRuiT offers a one-stop solution of lithium energy storage systems for residential users. The energy storage systems from nRuiT are safe to use, have fast charging, long-lasting, high-temperature resistance, and come with a large capacity.

One of the most powerful home energy storage solutions from nRuiT is the Power Porter 9.0 and Power Porter 5.0.

Power Porter 9.0

The Power Porter 9.0 is combined with an inverter, photovoltaic (PV), and related accessories to build a residential energy storage system. The system is used to store the direct current (DC) generated by photovoltaic (PV) in the connected battery, and convert it into alternating current (AC), which is sent to the home grid.

The Power Porter 9.0 comes with an energy capacity of 9kWh and an Output of 5kW. Additionally, NRuiT offers five years warranty and more than 6000 circles life on the Power Port 9.0.

Power Porter 5.0

Like the Power Porter 9.0, the 5.0 mainly combines with an inverter, photovoltaic (PV), and related accessories to build a residential energy storage system.

Power Porter 5.0 uses LiFePO4 Battery Cell with the feature of a safe, long lifespan. The energy capacity of the product is 5kWh with an Output of 3kW and an IP Grade of IP3. Power Porter 5.0 has a least 5500 circles life, 10-15 years life span, and a five-year warranty.

All nRuiT lithium battery solutions are widely used in energy storage power systems such as firepower, water power, solar power stations, and wind power. The systems from nRuiT also provide uninterruptible power supplies for telecommunications, aerospace, military, and the manufacturing of electric tools, electric vehicles, electric motorcycles, and electric bicycles.
