Fixed valve-regulated sealed lead-acid battery (commonly known as maintenance-free battery) features
1. Sealing: It adopts battery slot cover and pole double seal design to prevent acid leakage. The reliable safety valve can prevent outside air and dust from entering the battery inside;
2, maintenance-free: strong water regeneration capacity, high sealing efficiency, so no need to replenish water or acid maintenance during the use of the entire battery;
3, safe and reliable: no acid spill, reliable safety valve automatic closure, explosion-proof equipment makes the battery more safe and reliable throughout the use;
4, long-life design: computer-designed corrosion-resistant lead calcium lead alloy grid, the use of ABS corrosion-resistant materials and extremely high sealing reaction efficiency to ensure the long life of the battery;
5, high performance:
1) The weight is higher than the energy, the internal resistance is small, and the output power is high;
2) High charge and discharge performance, self-discharge control is less than 2% per month (20 ° C);
3) The recovery performance is good. When the deep discharge or the charger fails, after the short circuit is placed for 30 days, the balanced charging method can still be used to restore the capacity;
4) Since the internal resistance, capacity, and float voltage of the single battery are consistent, the battery does not need to be charged in a floating state.
6, the temperature adaptability: can be safely and safely used at -30 ° C ~ 50 ° C;
7. Safe and easy to use and transport: Fully charged and discharged from the factory, no free electrolyte, the battery can be placed horizontally, and can be transported by water and land without dangerous materials;
8. Affordable: The extremely high performance of the battery, the long service life and the extremely low maintenance cost ensure that the user gets an economical product.
Products can be widely used in electric power, communications, railway, petroleum, aviation, water conservancy, geology, rail transit and other fields to replace ordinary batteries, so that product performance can be improved.
