Product Details

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

Negative plate

Pasted flat type, high rate discharge performance;


PVC-SiO2 separator, low internal resistance, high pore rate;                                           

Positive plate

Tubular type, with die-casting thick Pb-Ca grid;


Gel electrolyte uses imported silica, lower internal resistance;

Safety valves

Good sensitivity, safe and reliable,
