Valve-regulated lead-acid battery is a kind of lead-acid battery. The valve-regulated lead-acid battery case and cover are made of ABS synthetic resin or flame-retardant plastic, the positive and negative electrodes are paste-coated plates with special lead-calcium alloy grids, and the separator is made of high-quality ultra-fine glass fiber cotton (felt). Equipped with a safe and reliable pressure reducing valve to implement high-pressure exhaust. my country began to develop small valve-regulated sealed lead-acid batteries in 1986.

1. Avoid overcharging the battery in the UPS power supply. Because overcharging is easy to cause the bending of the positive and negative plates inside the battery and the active material on the surface of the plates to fall off. When the consequences are light, the available capacity of the battery will decrease, and in severe cases, the battery will be damaged. the

The battery is mainly composed of positive plate, negative plate, separator, battery shell, cover, lead nail, positive pole, negative pole, rubber cap and electrolyte.

The rubber cap is a very important part of the small VRLA battery, also known as the exhaust valve. The opening and closing pressure of the rubber cap is a very critical performance indicator.
