Nickel Cadmium Batteries - HSL+ for Solar Photovoltaic

HBL HSL+ nickel cadmium batteries were developed to store the energy for critical and demanding applications at solar or renewable energy sites. Utilising a customised separator the battery recombines products of charging to virtually eliminate water loss. These batteries are completely reliable, with minimal maintenance, withstand deep discharges, rough treatment, over long periods and operate over a very wide temperature range.

HSL+ cells are available with standard or seismic racking - shock resistant polypropylene casing material and flame arresting vents are standard. All connectors are nickel plated copper and the robust nickel plated steel terminals are provided with take-off lugs to accept customer cables.
