Vented Pocket Plate - HSL+

 HSL+ : Nickel Cadmium Pocket Plate Batteries

HSL+ type of Nickel Cadmium Battery is developed by HBL to supply power to critical and demanding applications like solar photovoltaic or renewable energy. These batteries are completely reliable, with minimal maintenance, withstand deep discharges, rough treatment, over long periods and operate at wide temperature range.

HSL+ cells are available with strong steel frame structure, shocks-resistant polypropylene casing material and flame arresting spill-proof vent. This battery gets better internal recombination by using special polypropylene fibrous type of separator.
