    The principle of maintenance-free lead-acid batteries is based on the following aspects

    Mar , 07 2025
    1、Basic Electrochemical Principles The charging and discharging process of maintenance-free lead-acid batteries is based on electrochemical redox reactions. When discharging, metal lead is the negative pole, the oxidation reaction occurs, the electrode reaction formula is Pb +SO42-===PbSO4+ 2e-; lead dioxide is the positive pole, the reduction reaction occurs, the electrode reaction formula is PbO...

  • Difference between kVA and kw

    Difference between kVA and kw

    Mar , 15 2025
    kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...

    Advantages of lead-acid colloidal batteries

    Mar , 28 2025
    1. Long service life: The colloidal electrolyte can form a solid protective layer on the plate, reduce the bending and short circuit of the plate when used under heavy load, delay the softening and shedding of the plate, and make the battery life reach 1.5-2 times that of ordinary lead-acid batteries. 2. High safety: The electrolyte is solid, sealed, and never leaks. There is no acid mist gas prec...

    How to choose the right lithium battery

    Mar , 28 2025
    1. Identify application scenarios The purpose of lithium batteries directly affects parameter selection: Portable devices (mobile phones, drones, cameras): give priority to high energy density (such as ternary lithium batteries) and lightweight. Electric vehicles/power tools: require high discharge rate (C-rate) and long cycle life (such as lithium iron phosphate batteries). Energy storage systems...

    What Is UPS Input Power Factor and Why It Matters

    Apr , 12 2025
    Power factor (pf) is the difference between the actual energy consumed in an AC circuit and the apparent power. It will be calculated as a decimal or percentage between 0-1 pf and 0-100%, i.e. 0.9 pF=90%. Meaning of UPS power factor UPS input power factor UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of the power supply, but also the load of t...

  • The reason why LiFePO4 batteries cannot be charged but can be discharged below 0℃

    The reason why LiFePO4 batteries cannot be charged but can be discharged below 0℃

    Jun , 07 2025
    Why LiFePO4 Batteries Cannot Be Charged Below 0°C but Can Still Discharge The reason why LiFePO4 (Lithium Iron Phosphate) batteries, such as the EverExceed battery range, cannot be charged below 0°C yet can still discharge lies mainly in their electrochemical characteristics and safety considerations. 1. Why Charging Is Restricted at Low Temperatures Lithium Plating Risk: At sub-zero temperatures,...

  • 8 tips to avoid ground loops when dealing with signal level circuits

    8 tips to avoid ground loops when dealing with signal level circuits

    Jun , 27 2025
    Ground loops and signal noise General recommendation is to properly design and implement the facility's grounding system to avoid unwanted involvement of ground loops with the operation of the equipment. This kind of approach can also eliminate the need to consider equipment modifications and to engage in costly diagnostic efforts since most trouble involving common-mode noise is avoided in the si...

  • The Impact of High Temperatures on Lead-Acid Batteries and Recommended Solutions

    The Impact of High Temperatures on Lead-Acid Batteries and Recommended Solutions

    Jul , 19 2025
    Lead-acid batteries are widely used in energy storage, telecom base stations, and UPS systems. However, their performance is significantly affected by ambient temperature—especially under high-temperature conditions, which can lead to rapid degradation and potential safety risks. Below are six key impacts of high temperature on lead-acid batteries and how to address them: 1. Short-Term Capacity Ga...

    The Hazards of Overcharging Lead-Acid Batteries

    Aug , 08 2025
    1. Significant Capacity Decline ① During overcharging, excessive chemical reactions occur inside the battery. The active material, lead dioxide, on the positive plate gradually becomes loose and loses its original structural stability, reducing its ability to participate in electrochemical reactions. ② The active material, spongy lead, on the negative plate also experiences a coarsening of particl...
