Verify your Toughbook model before purchase
Confirm that your device belongs to the FZ-55 MK1 or MK2 family and cross-reference the part number against FZ-VZSU1HU, 3INR19/66-2B or 3INR19/66-2. The battery fits a long list of sub-models including FZ-55A, FZ-55B, FZ-55C, FZ-55D, FZ-55E and FZ-55F variants. It also supports several accessory part numbers such as FZ-VCN553 and FZ-VDR551. Do not order if your laptop uses a different series or voltage.
Li-ion cell with standard Toughbook mounting
The pack uses a lithium-ion chemistry rated at 10.8V and 68Wh, housed in a black casing that slots into the regular battery bay. No extra cables or adapters are required because the connector layout matches the factory design. The form factor aligns with the original latch mechanism so the battery locks securely during field use. Users who need hot-swap capability or a second bay should check whether their specific chassis supports that feature.
