Description du produit
The Toshiba Portege Z830 and Z930 were Toshiba’s competitive response to the 2011–2013 ultrabook wave — 13.3-inch, sub-1.1kg chassis targeted squarely at business travelers and corporate procurement. They sold heavily into enterprise accounts and government fleets across North America, Europe, and Japan. Over a decade later, these machines remain active in managed device inventories — held back by organizations extending asset lifecycles beyond the standard refresh cycle. The original OEM battery (assembly code P000552590, later revised to P000613950) is no longer stocked by Toshiba’s own service channels, which means the aftermarket is the only practical supply path.
What most listings miss entirely: the Dynabook R631 and R632 — sold in the Japanese domestic market under Toshiba’s Dynabook brand — use this exact battery. Same chassis dimensions, same connector, same 4ICP5/44/62-2 cell configuration. IT procurement teams dealing with mixed Japan-origin Toshiba fleets can order this part to cover both Portege and Dynabook R-series units under a single purchase order.
The cell chemistry here is Li-polymère, not standard cylindrical Li-ion — a distinction that matters operationally. Li-Polymer packs are flat-laminated cells designed for the thin ultrabook chassis. They cannot be physically substituted with a cylindrical-cell pack of the same capacity; the form factor is specific to this platform.

Caractéristiques et avantages
✅ 🧬 Li-Polymer, Not Cylindrical Li-ion — The Right Cell Chemistry for This Chassis
The Portege Z830/Z930 chassis was engineered around flat Li-Polymer cells to achieve sub-15mm thickness. Substituting a cylindrical Li-ion pack will not physically fit the battery bay. This replacement uses the correct laminated pouch cell construction — same form factor, same connector, same BMS communication protocol as the original Toshiba unit.
✅ 🏢 Built for Corporate Fleet Longevity Programs
Enterprise IT teams running extended asset lifecycles on Portege Z-series fleets face a single choke point: the original battery is no longer distributed through Toshiba’s service network. Factory-direct supply from us removes that dependency. One SKU, one purchase order, covers the entire Z830–Z935 generation and the Japan-market Dynabook R631/R632 equivalents simultaneously.
✅ 🔋 Honest 47Wh — No Inflated mAh Claims
14.8V × 3060mAh = 45.3Wh measured; the 47Wh rating accounts for actual pack-level output under load. Some market listings for this footprint advertise 3100mAh or even 3200mAh at the same watt-hour figure — those numbers don’t add up. Our spec sheet reflects what ships. For service contracts billing on runtime benchmarks, accurate capacity data matters.
✅ 🔧 Depot-Ready Installation for Trained Technicians
Unlike the tool-free latch-release batteries on the Satellite A/L-series, the Portege Z830/Z930 requires back panel removal (5–7 Phillips screws, depending on sub-model). Replacement is straightforward for any trained repair technician and takes approximately 8–12 minutes per unit. No firmware reset or BMS reset required after installation.
✅ 🛡️ Full PCB Protection Stack
Overcharge cutoff at 4.2V per cell, over-discharge cutoff at 2.5V per cell, overcurrent protection, short-circuit shutdown, and NTC thermistor for thermal monitoring. All protection logic is active in hardware — not reliant on host OS battery management firmware.

FAQ
Q1: Does this battery also fit the Toshiba Dynabook R631 and R632?
A: Yes. The Dynabook R631 and R632 — sold in Japan under Toshiba’s Dynabook brand — share the same chassis platform as the Portege Z830/Z930. Battery bay dimensions, connector type, and cell configuration (4ICP5/44/62-2) are identical. IT buyers managing mixed Japan-origin and international Toshiba fleets can consolidate under a single PA5013U-1BRS order.
Q2: Why does this battery use Li-Polymer instead of standard Li-ion, and does it matter?
A: It matters for sourcing accuracy. The Portege Z830/Z930 chassis was engineered at under 15mm thickness — too thin for standard cylindrical 18650 Li-ion cells. The original Toshiba design uses flat laminated Li-Polymer cells. Our replacement follows the same construction. A cylindrical-cell pack marked with the same mAh will not fit the physical bay on these machines, regardless of the capacity rating printed on the label.
Q3: My Portege Z930 shows a “Battery Not Recognized” warning after installing a replacement. What causes this?
A: This warning typically appears when the BMS ID chip on the replacement battery has not been programmed to match Toshiba’s authentication handshake. Our units are programmed with the correct BMS ID before shipment. If the warning still appears after installation, the most common cause is an incomplete connector seating — power off, disconnect and reseat the battery connector firmly, then restart. If the issue persists, contact us directly for a replacement unit assessment.
Q4: What is the actual runtime on a Portege Z930 after replacement?
A: Under standard business workloads — Office applications, web browsing, Wi-Fi active, display at 50–60% brightness — a fresh 47Wh cell in a Portege Z930 delivers approximately 3.5–5 hours, depending on firmware power profile and background load. These machines have Intel 3rd-gen ULV processors with a 17W TDP; runtime is meaningfully better than the heavier Satellite A/L platforms. Setting a realistic 4-hour benchmark is appropriate for most enterprise use cases.
Q5: Can I order samples before placing a bulk order for our repair chain?
A: Yes. Sample orders are available for repair chain buyers, IT distributors, and corporate procurement officers. Typical sample lead time is 3–5 business days. Submit an inquiry via the wholesale contact form with your business name and estimated monthly volume — we’ll respond with pricing and lead time confirmation.
Q6: Is the PA5013U-1BRS compatible with the newer Portege Z30 or Z20t series?
A: No. The Portege Z30 (Z30-A, Z30-B) uses a physically different battery — the PA5136U-1BRS (14.8V, 52Wh). The Z20t and Z10t use yet another form factor. The PA5013U-1BRS is specific to the first-generation Portege Z thin-and-light platforms (Z830/Z835/Z930/Z935) released between 2012 and 2014. Ordering this part for a Z30-series machine will result in a connector and form factor mismatch.
