    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...

    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...
