OPzV 12-45-Y Product Feature Floating design life: 20 years at 25℃ Cycle life(2V): >2000 at 80% DOD and 6000 at 25% DOD Self-discharge rate: ≤2%/Month High charge acceptance performance Wide operation temperature range: -40℃～70℃ Storage life: After fully charged, it can be storaged about 2...
Tubular battery Valve Regulated Lead Acid batteries are designed with a proven combination of GEL and Tubular technologies to offer a very high lever of reliability. Opzv batteries benefit from an optimized plate design which gives capacities in excess of the DIN standard values. In addition, this series offers both a longest float life and a high cycle life in widely industrial field.
Product Feature of tubular battery
Pasted flat type, high rate discharge performance;
PVC-SiO2 separator, low internal resistance, high pore rate;
Tubular type, with die-casting thick Pb-Ca grid;
Gel electrolyte uses imported silica, lower internal resistance;
Good sensitivity, safe and reliable,
