The CF-VZSU71U is the Panasonic OEM-designated “Long Life Battery” for the Toughbook CF-52 MK4\/MK5 and CF-53 MK1 through MK4 \u2014 a distinction that matters in B2B procurement and that most aftermarket product pages get wrong. The majority of listings lump the CF-VZSU71U together with the CF-VZSU46 as if they are identical. They are not. The CF-VZSU71U is rated at 69Wh \/ 10.8V \/ 6,750mAh<\/strong>. The CF-VZSU46 is rated at 87Wh \/ 10.65V \/ 8,550mAh<\/strong> (9-cell, 3S3P). These two units share the same connector and fit the same chassis, but they are not electrically equivalent. Fleet procurement managers sourcing replacements for CF-53 or CF-52 fleets need to confirm whether the original battery label reads CF-VZSU71U or CF-VZSU46 before placing any volume order.<\/p>\n

The CF-VZSU71U is specifically the battery Panasonic specified when the CF-52 MK4\/MK5 and CF-53 platform launched. Its capacity \u2014 69Wh nominal \u2014 is the correct OEM baseline for runtime estimates published in Panasonic’s official CF-53 spec sheets. If a department’s runtime SLA was set against Panasonic’s published specifications, it was set against a CF-VZSU71U, not an 87Wh aftermarket upgrade. For IT managers maintaining compliance with OEM power specifications in regulated environments (public safety dispatch systems, military logistics platforms, healthcare field devices), this distinction is material.<\/p>\n

Physical dimensions: approximately 165mm \u00d7 82mm \u00d7 21mm, weight approx. 465g \u2014 matching Panasonic’s published OEM spec for this unit.<\/p>\n
