Batteries – A detailed comparison of two types of VRLA batteries
There are two types of VRLA batteries: one is VRLA battery using ultra-fine glass fiber membrane (AGM); the other is VRLA battery using colloidal electrolyte (GFL) (abbreviated as GFL-VRLA battery). They all use the principle of cathode absorption to seal the lead-acid battery. Therefore, there must be about 10% of the diaphragm gap in the […]
