“Next Gen” Valve Regulated Nickel Cadmium

This Ultra-low maintenance version of HBL’s pocket plate batteries offers the user the security of the most reliable nickel cadmium batteries while removing the need for watering. HBL’s VentPro ranges offer a recombination gas efficiency of more than 95%. No water additions are required in normal service.

The batteries can be supplied in racks (inc seismic approved versions) and cabinets. If required HBL can supply a perfectly matched battery charger to complement the battery and ensure correct charging.

HBL’s VentPro range complies with IEC 62259 and is certified by Intertek

The construction of VentPro is based on robust pocket plate technology by introducing special features to bring the water topping requirement to zero when operated as per recommended guidelines and needs only minimal preventive maintenance.
