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...
