What is a maintenance-free lead-acid battery?

 Maintenance-free lead-acid battery English is Valve Regulated Lead Battery (referred to as VRLA battery), its basic feature is the use of acid during the maintenance without water, the battery is sealed structure, will not leak acid, acid mist will not row, the battery cover One-way exhaust valve (also known as safety valve), the role of the valve when the battery inside the gas pressure exceeds a certain value, the safety valve automatically open, exhaust gas, and then automatically shut down, the conventional state of the valve is closed. VRLA batteries and traditional lead-acid batteries, the biggest difference is that the traditional non-sealed battery, due to evaporation, reaction process, the battery will lose acid loss of water, need to add acid and water regularly, the most common traditional battery is the car battery, life is called the battery Come.

 
AGM (Absorbed Glass MAT) as the diaphragm, the electrolyte adsorbed in the plate and the diaphragm, the poor fluid type design, the battery inside the battery, No flow of electrolyte. GEL (colloid) using silica as coagulant, the electrolyte adsorbed in the plate and colloid, the use of environmental adaptability. (From the application perspective): AGM: general life of 5-12 years, the temperature for -15 degrees to 40 degrees, affordable, high-current discharge is good, float use good; GEL: general life of 8-15 years, Temperature for -25 degrees to 60 degrees, the price is higher than the AGM, high current in general, the best use of floating charge;
 
Maintenance-free lead-acid battery voltage 2V, 4V, 6V, 12V, 24V. The capacity of the battery unit is AH. At present the industry generally to 20AH as the cut-off point, 20AH the following battery is called a small battery, 20AH above the battery known as the large and small batteries; small battery generally 20 hours rate to characterize the capacity, large batteries generally 10 hours rate Characterization of capacity, there is no special that the battery capacity defaults to 10-hour rate or 20-hour rate.
