Valve-controlled maintenance-free lead-acid batteries are special supporting products for solar power systems, wind power generation systems, uninterruptible power supplies (UPS), inverters, EPS, etc.
With high sealed reaction efficiency based on a unique technology, the product needs no maintenance by means of water or acid supplementation in its whole life.
+High safety and reliability
It is provided with a full automatic safety valve to avoid damage as a result of an abnormal internal pressure caused by the gas generated in process such as charge. In normal floating charge, it emits neither electrolyte nor acid mist because it is a completely sealed battery. The battery pack will be safer if used with a patented battery tray.
The corrosion-resistant multi-element alloy grid including elements such as calcium, lead and tin, and the ABS corrosion-resistant shell, both accurately designed by computer, have extremely high sealed reaction efficiency, thus guaranteeing a longer battery life.
+Low self discharge rate
A multiple-elemennt alloy including special calcium and lead is used, and the battery separator, the electrolyte and the impurities generated in production procedures are strictly controlled. Thus, the battery not charged within six months can be used normally at 20ºC.
With copper-core silvered terminals and special design, the product has extremely great electrical performance.
+Great adaptability to environment
The product adapts to severe climates and can even be used at an ambient temperauture of -25ºC to 50ºC.
The product has high sealed reation efficiency, so it can be used normally and has no leakage when placed vertically or horizontally.
It is quiet and generates no pollutants, so it can be put in the same room with articles such as electronic instruments and the battery room needs no corrosion-proof actions against acids.
