The E-HL9 is a high capacity 88Wh battery featuring PowerLink, which enables two batteries to be docked (or "stacked" together), doubling the capacity to 176Wh for longer run times and high power needs. The 5 LED power status display gives an accurate reading of capacity in 20% increments, while Digi-View displays the battery levels in many of today’s camera viewfinders. Battery Management System (BMS) can be used for
enhanced diagnostics and a comprehensive review of the battery’s history of use.
