The CF-VZSU1AJS and CF-VZSU1AW are the same battery. The difference is purely a regional catalog suffix: CF-VZSU1AJS is the Panasonic Japan\/APAC market part number; CF-VZSU1AW is the North American equivalent. Both refer to the 22Wh \/ 11.1V \/ 3-cell Standard Battery for the Toughbook CF-33, and both fit the same chassis identically. This matters for procurement teams sourcing parts from mixed-region supplier databases: a Japanese government agency or APAC enterprise IT team searching their procurement system finds CF-VZSU1AJS; their North American counterpart finds CF-VZSU1AW. Ordering either will get you the same unit.<\/p>\n

What most competitor product pages covering this battery do not address adequately is the CF-33’s generational coverage<\/strong>. The CF-33 ran from MK1 (2016, Core i5-7300U) through MK4 and beyond, and the Standard Battery bay and connector remained unchanged throughout. Yet the overwhelming majority of aftermarket listings restrict compatibility to “CF-33 MK1” \u2014 because that was the only MK generation documented in the early product entries that everyone else copied. MK2, MK3, and MK4 units are all confirmed compatible with the same CF-VZSU1AJS \/ CF-VZSU1AW battery. For IT depot managers maintaining a mixed-generation CF-33 fleet, this means one SKU covers the entire install base regardless of which procurement wave each device entered service in.<\/p>\n

The other context gap in most listings: the CF-33 Standard Battery is specifically the flat-profile configuration<\/strong>. The CF-33 also accepts the CF-VZSU1BW Extended Battery, which delivers higher capacity but requires the bump-out battery cover that physically extends beyond the chassis baseline. The Standard Battery (CF-VZSU1AJS \/ CF-VZSU1AW) installs flush with the chassis underside \u2014 critical for maintaining the CF-33’s IP65 ingress protection rating and MIL-STD-810G certification. A Standard Battery installed in a chassis with a bump-out cover will rattle; a CF-VZSU1BW installed in a Standard cover slot will physically not fit. Confirm the chassis cover configuration before placing a volume order.<\/p>\n
