Nickel Cadmium Valve Regulated Pocket Plate Batteries

HBL Power Systems offers Nickel Cadmium Valve Regulated Pocket Plate (VRPP) Batteries.

The Valve Regulated Pocket Plate (VRPP) battery developed by HBL combines the unmatched reliability of Nickel Cadmium pocket plate technology, with the convenience of reduced maintenance requirements. VRPP’s controlled recombination system, with valve regulated venting means no water replenishment is needed during its lifetime under recommended operating conditions. VRPP perform in severe in temperatures ranging from -20 C to +50 C, and can survive over-discharge, reversal or prolonged overcharge with no damage.

The Proven Pocket Plate design of HBL consists of the active materials encapsulated between folded steel strips which are perforated from both sides. This double perforation method increases the effective surface area by 30% and helps in better utilization of the active material thereby making the battery more efficient. In addition to the Pocket Plate design, the VRPP batteries use a special separator which allows gases generated during charging to recombine inside the cell thus ensuring no water is lost. This makes the VRPP battery with maintenance. A self resealing type vent cap is also employed to release any excess pressure developed inside the cell during abnormal operation.

The construction of HBL VRPP Cell is based upon conventional proven pocket plate technology, introducing special features to eliminate the need for water topping. The separator is a key feature of the VRPP Battery.
