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 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...
