Renowned for their exceptional performance and durability, lithium iron phosphate (LiFePO4) batteries have emerged as a frontrunner in battery technology. It is crucial to comprehend the cycle life of LiFePO4 batteries and the variables that impact their longevity when procuring and utilizing them. This article delves into an in-depth examination of the cycle life of LiFePO4 batteries and the myriad factors that influence their lifespan. Cycle life denotes the number of complete charge and discharge cycles a battery can undergo while maintaining its rated capacity. Essentially, it gauges the rate of battery degradation over time, offering a more accurate assessment of its lifespan than mere years alone. The cycle life of lithium iron phosphate batteries is intricately linked with the depth of discharge (DoD), representing the extent to which the battery is discharged. For instance, Taking PLB’s IFR26650-30B battery as an example : a battery’s cycle life at 100% DoD…

Lithium batteries exhibit a wider temperature range for discharge (-20°C to 60°C) compared to charging (0°C to 45°C), a fact commonly noted in lithium battery data sheets across various brands and models. This prompts the question: Why do lithium batteries necessitate higher temperatures during charging? The rationale lies in the phenomenon of “lithium plating,” which occurs at temperatures below 0°C during the charging process. This is primarily attributed to diminished molecular mobility under low-temperature conditions. Notably, lithium-ion in graphite is inhibited, resulting in a decrease in the intercalation rate and a lithium plating reaction on the graphite surface. Consequently, this process elevates internal resistance and results in capacity loss within the lithium battery. To grasp the chemistry underlying the lithium plating reaction, understanding the operational mechanism of lithium batteries is imperative. These batteries store and discharge energy by facilitating the migration of lithium ions between positive and negative electrodes. During…

When purchasing rack-mounted UPS batteries, the buyers often mention professional terms such as 1U and 2U. What does‘U’mean? The ‘U’ stands for unit, which represents the external dimensions of the server. The size is determined by the Electronic Industry Agreement (EIA) as an industry group. The reason why the external dimensions of the server are stipulated is to facilitate the server to maintain an appropriate distance when installed on the rack, and to correspond one-to-one with the screw holes fixed on the rack to facilitate screw fixation. The “1U/2U rack-mounted UPS battery” is actually a UPS battery product that meets EIA specifications, and the product can be successfully installed on a server rack of corresponding size. The corresponding size and height of 1U is 1.75 inches = 4.445 centimeters, and 2U is twice the size of 1U, which is 8.89 centimeters, and so on. The design of the 1U/2U rack-mounted…

As we all know, lithium battery manufacturing is a highly technical, complex, and multi-process task, and each process has a vital impact on the battery. This article mainly explains to you the pre-charging in the lithium battery manufacturing process. Why is pre-charging required? What role does pre-charging play? Let’s explore together. Manufactured lithium batteries usually need to be pre-charged before being officially charged. Pre-charging is the process of charging the battery with a lower current. Its main purpose is to extend battery life and improve battery performance. The following is a detailed explanation on the necessity of pre-charging lithium batteries. Activating the battery: Newly produced batteries are in an extremely low voltage state. Pre-charging can slowly increase the voltage of the battery to a safe level by applying a smaller current to activate the battery and the chemicals in the battery, thereby increasing the battery capacity, improve its performance and…

There are currently many types of off-grid solar batteries available on the market, and the various marketing advertisements are dazzling. It is not easy to choose the battery that is most suitable for you. This article will introduce you the main Off- grid solar batteries currently on the market. I hope it can help you make your choice.

If your lithium iron phosphate battery has been idle for a long time and is unable to power your device, it is not necessarily a battery failure. It may have entered a sleep mode, which is a “self-protection” mechanism of the battery. So, how can you wake up a sleeping lithium iron phosphate battery? Let’s find out! If you are unfamiliar with lithium iron phosphate batteries, you may not be aware of the sleep mode or protection mode. These modes are part of the built-in Battery Management System (BMS) of the battery, designed to facilitate the management of lithium iron phosphate batteries and to continuously monitor and detect the battery’s status. By setting certain conditions, the BMS activates protective measures to shut down the battery until it can safely operate again. Sleep mode means that the lithium iron phosphate battery is in a state of low power or no usage…

A UPS (uninterruptible power supply) system is a device used to provide stable, uninterrupted power supply. It is widely used in various places that require continuous power supply, such as data centers, medical facilities and communication infrastructure. In order to ensure that sufficient power is provided during power grid outages or power fluctuations, UPS battery float charging plays a vital role. UPS battery float charging means that when the battery is fully charged, the charger continues to charge the UPS battery with a constant small current to balance the natural discharge of the battery, thereby ensuring that the UPS battery can remain fully charged during a power outage. The specific principle is as follows: In the power supply system, the rectifier and the battery are connected in parallel on the feeder. When the mains power is normal, the rectifier will supply power and at the same time recharge the battery…
