Sealed lead acid batteries introduction
Introduction of Sealed lead acid batteries
French Prandt in 1859 invented lead-acid batteries, has gone through nearly 150 years of development, lead-acid batteries in theoretical research, product variety and variety, product electrical performance, etc. have been improved, whether in traffic , Communications, electricity, military or in navigation, aviation in various economic fields, lead-acid batteries have played an indispensable role.
According to the structure and use of lead-acid battery difference, the battery is divided into four categories: 1, start with lead-acid batteries; 2, power lead-acid batteries; 3, fixed-valve sealed lead-acid batteries; Including small valve-regulated sealed lead-acid batteries, miner's lamp with lead-acid batteries.
A single cell lead-acid battery nominal voltage is 2.0V, can discharge to 1.5V, can charge to 2.4V. In the application, often with six single-cell lead-acid batteries in series to form a nominal 12V lead-acid batteries. There are 24V, 36V, 48V and so on.
Key Features
Safe seal
In normal operation, the electrolyte will not leak from the terminal or housing of the battery.
The special absorbent baffle holds the acid, and there is no free acid inside the battery, so the battery can be placed in any position.
Deflation system
After the battery pressure exceeds the normal level, VRLA battery will release excess gas and automatically re-sealed to ensure that there is no excess gas in the battery.
Maintenance is simple
Because of the unique gas composite system to produce the gas into water, in the use of VRLA battery process does not need to add water.
long lasting
Using a corrosion-resistant structure of the lead-calcium alloy fence VRLA battery can be used for 10-15 years.
Quality and high reliability
The use of advanced production technology and strict quality control system, VRLA battery quality and reliable performance. Voltage, capacity and seal on-line 100% inspection.
safety certificate
All VRLA batteries are UL certified.
