Product Description
he Toughbook CF-C2 MK1 ships with three distinct battery options — and this is the sourcing detail that trips up the majority of aftermarket procurement orders for this platform. All three P/Ns are frequently grouped together on competitor product listings as if they are interchangeable. They are not:
-
CF-VZSU80U — Standard Battery: 70Wh / 10.8V / 6,800mAh, 14-hour OEM runtime
-
CF-VZSU82U — Lightweight Battery: lower capacity (~43Wh), lighter physical weight, reduced runtime
-
CF-VZSU83U — Extended Battery: 94Wh / 10.8V / 8,700mAh, requires extended battery cover, larger chassis footprint
All three use the same connector family, which is exactly why bulk orders go wrong: a procurement manager orders “CF-VZSU80U” and receives CF-VZSU82U lightweight units because the supplier treats all three as equivalent SKUs. Runtime under the lightweight battery is materially shorter — not a quality defect, but a wrong-variant delivery. Before placing any volume order, confirm the original battery P/N from the label inside the chassis bay.
The CF-C2 MK1 itself is a semi-rugged 12.5-inch convertible tablet-laptop — deployed primarily in field inspection, mobile documentation, healthcare ward rounds, and light logistics management. Unlike the fully rugged CF-30/CF-31/CF-53 platforms (which require 9-cell batteries with the CF-VZSU46/71U family), the CF-C2 targets users who need rugged protection in a slimmer form factor. Its battery demand profile is different: lower peak draw than a fully rugged unit, but continuous active use throughout a working day without AC access. The 70Wh CF-VZSU80U is sized for that 14-hour use pattern.
Physical dimensions are approximately 192mm × 71mm × 21mm, weight approximately 440g — matching Panasonic’s published OEM spec for the Standard Battery configuration.

Features & Advantages
✅ Three-Variant Clarity — Avoiding the Most Common CF-C2 Ordering Error
The CF-C2 MK1 platform ships with three distinct battery types (Standard / Lightweight / Extended) that share a similar connector family but are not interchangeable. Most aftermarket suppliers list all three P/Ns on a single product page. We document the distinction explicitly on every order confirmation and cross-reference sheet — giving IT procurement managers and depot technicians a clear verification method and reducing wrong-variant deliveries on bulk orders.
✅ 70Wh Standard Capacity — Full 14-Hour OEM Runtime Profile
Panasonic’s published operational time for the CF-C2 MK1 with CF-VZSU80U is 14 hours under standard mixed workloads. This is the runtime figure your end users and SLA documentation are based on — not the reduced figure from a Lightweight Battery substitute. For healthcare IT and field service organizations where shift coverage without AC access is a hard operational requirement, the 70Wh Standard Battery is the only correct replacement tier.
✅ 6,800mAh Grade-A Cells, OEM Minimum Spec Met
Panasonic’s OEM minimum specification for this battery is 6,400mAh. Our production targets 6,800mAh typical, batch-verified at ≥95% of rated 70Wh before shipment. Cell grouping held within ±20mAh. For fleet operators managing CF-C2 MK1 units across a large semi-rugged device pool, consistent capacity per batch means predictable runtime across the fleet — not a spread of 64Wh to 70Wh units from the same order.
✅ OEM Physical Dimensions — Exact Standard Bay Fit
At approximately 192mm × 71mm × 21mm / 440g, this replacement matches Panasonic’s published Standard Battery dimensional spec for the CF-C2 MK1. The Standard Battery slot has a specific depth profile — the Extended Battery (CF-VZSU83U) protrudes beyond the chassis baseline because it exceeds this envelope. A dimensionally matched Standard Battery installs flush, maintains the CF-C2’s semi-rugged ingress protection rating, and avoids the connector stress that results from imprecise fitment.
✅ Factory Direct for Government and Enterprise Semi-Rugged Fleet Supply
The CF-C2 MK1 was widely deployed in government field offices, utility inspection teams, healthcare mobile workstations, and similar environments. Replacement battery demand for these fleets is typically managed by IT departments on quarterly or annual maintenance contracts. Our factory-direct pricing structure removes distributor margin from the cost equation — suited for procurement offices running multi-unit refresh cycles and B2B resellers serving the Panasonic semi-rugged installed base.

FAQ
Q1: What is the actual difference between CF-VZSU80U, CF-VZSU82U, and CF-VZSU83U — are they all the same battery?
A: No — these are three different products for the CF-C2 MK1 platform. CF-VZSU80U is the Standard Battery: 70Wh / 10.8V / 6,800mAh, 14-hour runtime. CF-VZSU82U is the Lightweight Battery: lower capacity, lighter weight, reduced runtime — designed for users prioritizing portability over endurance. CF-VZSU83U is the Extended Battery: 94Wh / 8,700mAh, physically larger with a bump-out cover, for maximum runtime. Most aftermarket listings treat all three as interchangeable under one product page — they are not. Open the CF-C2 battery bay and read the original P/N label to confirm which variant your unit shipped with before placing any volume order.
Q2: Does the CF-VZSU80U only fit the CF-C2 MK1, or does it also cover other CF-C2 generations?
A: Panasonic’s official designation for CF-VZSU80U is specifically the CF-C2 MK1. The CF-C2 product line was announced end-of-life by Panasonic in October 2016, and later MK generations (MK2 and beyond) may use updated battery P/Ns or different configurations. For any CF-C2 unit other than MK1, open the chassis and verify the original battery label P/N directly — do not assume compatibility based on the CF-C2 model name alone.
Q3: My Toughbook CF-C2 MK1 shows full charge but runtime is only 5–6 hours — is the CF-VZSU80U battery defective?
A: Not necessarily. Three likely causes: (1) Battery capacity has degraded — after 300–400 cycles, a 70Wh pack typically holds 60–70% of original capacity, which directly reduces runtime from 14 hours to 8–10 hours. Check actual full charge capacity vs. design capacity using Panasonic’s Battery Recalibration Utility or HWiNFO64. (2) The unit may have shipped with a CF-VZSU82U Lightweight Battery rather than a CF-VZSU80U Standard Battery — both are sold as “CF-VZSU80U compatible” by many aftermarket suppliers. Verify the installed P/N. (3) If it’s a new replacement unit showing low runtime immediately, the battery was under-capacity at production — request a replacement under warranty.
Q4: When should a CF-VZSU80U battery be replaced in a managed semi-rugged device fleet?
A: Under typical managed deployment — one full charge-discharge cycle per shift, five days per week — a Grade-A 70Wh CF-VZSU80U reaches approximately 70–75% of original capacity around cycle 350–450, corresponding to roughly 16–22 months of daily use. The practical replacement trigger is when runtime under standard workloads drops below 9–10 hours, indicating the cell has degraded past the point where full-shift field coverage is reliable. Use Panasonic’s Battery Recalibration Utility to track full charge capacity against design capacity across the fleet and schedule replacements proactively rather than reactively.
Q5: Can I order CF-VZSU80U sample batteries with test documentation before placing a bulk fleet order?
A: Yes. Sample units ship within 3–5 business days with a full electrical test report covering actual discharge capacity versus rated 70Wh (acceptance threshold ≥95%), internal resistance per cell group, and thermal cycling test data. Bulk production lead time is 7–15 business days. Accepted payment terms: T/T, L/C, and platform escrow. For government procurement teams requiring specific documentation — certification copies, product spec sheets, or test reports formatted for procurement records — these are provided with the sample shipment at no additional charge.
Q6: How do I verify I’m ordering CF-VZSU80U (Standard) and not accidentally receiving CF-VZSU82U (Lightweight) batteries in my bulk order?
A: Request the following from your supplier before confirming a bulk order: (1) Actual Wh rating confirmation in writing — CF-VZSU80U is 70Wh; CF-VZSU82U is lower. (2) Batch discharge test report showing actual measured capacity per unit — this makes any under-capacity substitution immediately visible. (3) Physical photo of the unit label showing the specific P/N. On our production batches, each unit is labeled with the exact P/N and Wh rating, and batch QC documentation is available for incoming inspection at your depot. If a supplier cannot provide discharge test data by batch, that is the clearest indicator they are sourcing mixed or substituted variants.
