Description du produit
The CF-VZSU1BW is Panasonic’s Long Life Battery for the Toughbook CF-33 — and it requires more pre-order verification than any other battery in the CF-33 ecosystem. The CF-33 ships in two distinct bottom panel configurations: a standard flat panel et un tall bottom panel. These are not interchangeable covers. The tall bottom panel is physically thicker, creating a larger internal cavity that accommodates the CF-VZSU1BW’s 3-cell, 45Wh pack. The standard flat panel cannot physically close over the CF-VZSU1BW. This is not a nuance — ordering CF-VZSU1BW batteries for a CF-33 fleet that shipped with flat panels creates a parts-incompatibility problem at the depot that no amount of rework resolves without sourcing the correct covers.
Compare the two CF-33 battery options:
-
CF-VZSU1AW — Standard Battery: 22Wh / 1,990mAh / flat panel / ~5 hours single / ~10 hours dual
-
CF-VZSU1BW — Long Life Battery: 45Wh / 4,120mAh / tall panel required / ~8–10 hours single (MK1) / ~7 hours (MK2–MK4) / up to 20 hours dual
The Long Life Battery delivers more than double the capacity of the Standard Battery per unit. In dual configuration — two CF-VZSU1BW units installed simultaneously, one in the tablet section and one in the keyboard base — the CF-33 delivers Panasonic’s published maximum of approximately 20 hours combined runtime on MK1 hardware. That figure positions the CF-33 with dual Long Life batteries as one of the longest-running rugged 2-in-1 platforms in the market, relevant for public safety operations, military field logistics, and remote utility crews running extended deployments.
One additional procurement detail: the CF-33 also supports mixed configurations — one CF-VZSU1AW (Standard) and one CF-VZSU1BW (Long Life) installed simultaneously. This is possible because each position has its own cover. A CF-33 unit with a tall panel in the keyboard base and a flat panel in the tablet section can run one of each. Procurement teams ordering for mixed-configuration fleets need to account for both cover types when specifying battery orders.

Caractéristiques et avantages
✅ The Critical Pre-Order Check Most Suppliers Don’t Mention
The CF-VZSU1BW requires the CF-33’s tall bottom panel — the battery physically protrudes beyond the standard panel envelope. Most aftermarket listings describe this as “compatible with CF-33” without any qualification. IT procurement managers who order CF-VZSU1BW units for a CF-33 fleet that shipped with standard flat panels will receive batteries that cannot close the chassis. Verify panel configuration before placing any volume order. Our order process includes a panel configuration verification step for bulk purchases — this prevents receiving a shipment that your depot cannot install.
✅ Double the Capacity of Standard Battery — 45Wh vs 22Wh Per Unit
At 45Wh / 4,120mAh per unit, the CF-VZSU1BW delivers 2.05× the capacity of the Standard CF-VZSU1AW (22Wh). Single-battery runtime on MK1 hardware reaches 8–10 hours under mixed workloads; MK2 through MK4 platforms return approximately 7 hours due to higher platform power draw. For field deployments where even the Standard Battery’s 5-hour single runtime is insufficient, the Long Life Battery is the correct specification choice.
✅ Dual Long Life Configuration: Up to 20 Hours — Maximum CF-33 Runtime
Two CF-VZSU1BW units installed simultaneously — one in the keyboard base, one in the tablet section — deliver Panasonic’s published maximum of approximately 20 hours combined runtime on MK1 hardware. This is the highest runtime configuration available on the CF-33 platform. For public safety officers on 16-hour shifts, military logistics operations with no charging infrastructure, or utility field crews on extended remote site deployments, this dual Long Life configuration eliminates battery management as an operational variable entirely.
✅ All CF-33 MK Generations — MK1 Through MK4
The CF-VZSU1BW Long Life battery bay and connector are unchanged across all four CF-33 MK generations. A single SKU covers the entire CF-33 Long Life install base. For depot operators managing mixed-generation CF-33 fleets where all units have tall panels, no generation-specific variant ordering is required — one P/N handles MK1 through MK4.
✅ Factory Direct for Government and Public Safety Fleet Supply
No distributor margin. Pricing reflects factory-direct cost structure, suited for government IT sustainment teams, public safety equipment officers, and B2B resellers serving the Toughbook installed base. Rolling small-batch replenishment is supported. Private label packaging and procurement documentation packages — test reports, certification copies, product spec sheets — are available with sample orders before any production commitment is required.

FAQ
Q1: What is the difference between CF-VZSU1BW and CF-VZSU1AW — can I use either one in my CF-33?
A: These are two different batteries for two different CF-33 chassis configurations. CF-VZSU1AW is the Standard Battery: 22Wh / 1,990mAh, installs with the flat bottom panel, back of the device is flush. CF-VZSU1BW is the Long Life Battery: 45Wh / 4,120mAh, requires the tall bottom panel — the battery is physically thicker and the chassis needs the matching taller cover to close. You cannot install a CF-VZSU1BW into a CF-33 that has a standard flat panel. Before ordering, physically check whether your CF-33 unit has a flat or tall bottom panel — or check the original purchase configuration documentation.
Q2: How do I tell if my CF-33 has the tall bottom panel required for CF-VZSU1BW?
A: The easiest method is visual: flip the CF-33 over and look at the bottom panel profile. A flat panel sits flush with the chassis edges. A tall panel is visibly thicker — there is a clear step or raised section compared to the rest of the chassis underside. You can also check the original Panasonic configuration specification for the unit’s serial number through Panasonic’s service portal, or look at the original order documentation to see whether “Long Life Battery” was specified at purchase. If in doubt, contact us with your unit’s serial number before placing a bulk order and we can advise.
Q3: What runtime does the CF-VZSU1BW deliver, and how does dual configuration work?
A: Single CF-VZSU1BW runtime: approximately 8–10 hours on MK1 hardware under mixed workloads; approximately 7 hours on MK2, MK3, and MK4 due to higher platform power consumption. Dual configuration — two CF-VZSU1BW units, one in the keyboard base and one in the tablet section — delivers Panasonic’s published maximum of approximately 20 hours combined on MK1. The CF-33 also supports a mixed configuration: one CF-VZSU1BW (Long Life) and one CF-VZSU1AW (Standard), which delivers approximately 15 hours combined. The system manages dual-battery discharge automatically.
Q4: Can I upgrade a CF-33 from standard battery to Long Life battery without replacing hardware?
A: Not without changing the bottom panel. The CF-VZSU1BW is physically larger than the CF-VZSU1AW and cannot fit within the flat panel enclosure. To upgrade a CF-33 from Standard Battery configuration to Long Life Battery configuration, you need both the CF-VZSU1BW battery and the tall bottom panel cover. Panasonic sells the tall panel as a separate service part. For bulk fleet upgrades, confirm whether the tall bottom panel is available through your Panasonic service channel before committing to battery-only procurement. A battery-only order without the matching covers will result in uninstallable stock.
Q5: Can I order CF-VZSU1BW samples with electrical test documentation before a bulk fleet order?
A: Yes. Sample units ship within 3–5 business days with a full electrical test report: actual discharge capacity versus rated 45Wh (acceptance threshold ≥95%), internal resistance per cell, and thermal cycling test data. For government or public safety procurement teams requiring documentation packages — certification copies, product spec sheets, test reports formatted for procurement records — these are provided with the sample. Bulk production lead time is 7–15 business days. Accepted payment terms: T/T, L/C, and platform escrow.
Q6: When should CF-VZSU1BW batteries be replaced in a managed CF-33 fleet, and how does the higher capacity affect replacement intervals?
A: Under typical fleet use — one full charge-discharge cycle per shift, five days per week — a Grade-A 45Wh CF-VZSU1BW reaches approximately 70% of original capacity around cycle 350–450, corresponding to roughly 16–20 months of daily use. The practical replacement trigger is when single-battery runtime drops below 5.5 hours on MK2–MK4 hardware (from the ~7 hour baseline) or below 6.5 hours on MK1 hardware (from the 8–10 hour baseline). Because the Long Life Battery has more than twice the capacity of the Standard Battery, it can tolerate more absolute degradation before hitting the runtime threshold that affects operational readiness. Use Panasonic’s PC Information Viewer to monitor full charge capacity versus design capacity across all CF-33 units and schedule replacements before mid-shift failures occur.
