Applications
50AH-300AH VRLA batteries, also known as large capacity valve-regulated lead acid batteries, are applicable to a wide range of purposes, including emergency lighting, electric tools, electric toys, measuring apparatus, fire alarms, security alert systems, UPS systems, operating systems, medical apparatus and instruments, stand-by power supplements, computer backup power, electrical systems, railway systems, power plants, ship equipment, military equipment, telephone switchboards and more.

50AH-300AH VRLA battery Features:
1. Valve regulated lead acid (VRLA) batteries are maintenance-free, and feature a long service life.
2. The gas recombinating efficiency reaches 98 percent due to the use of an ultra-fine, highly efficient glass fiber (AGM) separator.
3. The use of the high tin alloy grid decreases the corrosion rate of the grid and prolongs the battery service life.
4. It has a low water loss without any noticeable electrolyte stratification.
5. An equalizing charge is not necessary.
6. A sensitive open and close valve manages to keep the air pressure within a range that is conducive to the gas recombination by letting the external air in and releasing the extra air.
7. 50AH-300AH VRLA batteries also feature a great recovery performance after long term discharging.
8. The battery has an outstanding safety performance. The electrolyte will not leak even during a period of high productivity and there is no battery expansion and crackle. It can also be upended.
9. A huge thermal capacity reduces the risk of thermal runaway, which also makes the battery less prone to dry out, thus offering the possibility of using it in poor conditions.
