Product Description
12V Lead Acid Battery, Storage VRLA Battery 20ah (SR20-12)

Valve regulated lead acid series UPS batteries are designed with AGM (Absorbent Glass Mat) technology, high performance plates and electrolyte to gain extra power output for common power backup system applications widely used in the field of UPS, Emergency Lighting System.

Battery Structure
1. Container/Cover: Made of UL94HB and LU 94V-0 ABS Plastic
2. Negative Plates: Use the special PbCa alloy grids, optimize the recombination efficiency and less gassing.
3. Separator: Import high quality AGM separator.
4. Postive Plates: PbCa grids minimize corrosion and prolong life.
5. Terminal post: Cooper material with maximum conductivity, enhance the high current rapidly.
6. Vent Valve: Allows the release of excess gas automatically for safety.

Application
UPS, solar systems, control systems, power systems, wind energy systems, telecommunication/communication systems & etc.

Characteristics
1. Excellent safety performance.
2. Good dischargeing performance.
3. Good stock-proof performance.
4. Good impact-proof performance.
5. Good resistance to overdischarge.
6. Good resistance to overcharge.
7. Good resistance to high current.
