Produktbeschreibung
The PA5208U-1BRS covers one of the more unusual cross-platform footprints in the Toshiba replacement battery catalog: a single cell pack shared across a Chrome OS Chromebook (CB30/CB35), a Windows 2-in-1 convertible (Satellite Radius and Fusion lines), and an education-targeted touchscreen laptop — all using the same internal Li-Polymer pack with the same connector, same cell configuration, and same OEM assembly codes (P000619700 / P000645710).
For school district IT departments or Chromebook fleet managers, this detail is operationally important: a repair shop servicing a mixed-device education deployment that includes both CB35 Chromebooks and Satellite Radius 14 Windows machines can order one SKU to cover both — a procurement consolidation most buying teams don’t realize is possible.
One critical exclusion that causes significant buyer confusion: The Satellite P55W-B series (including P55W-B5224, P55W-B5220) uses a completely different battery — PA5189U-1BRS (14.4V, 60Wh). The P55W-B is visually similar to the P55W-C but is a prior-generation platform with a different voltage requirement and connector. Ordering PA5208U-1BRS for a P55W-B machine is a guaranteed mismatch. Always confirm the machine generation (B vs. C suffix) before placing a fleet order.
The PA5208U-1BRS is also the correct battery for the Satellite Fusion 15 L55W-C — a 15.6-inch 360-degree hinge 2-in-1 that Toshiba branded separately from the Radius line. Both “Radius” and “Fusion” nomenclature refer to Toshiba’s convertible hinge design; the battery bay and connector are the same across both branding variants.

Merkmale und Vorteile
✅ 🖥️ One Battery, Three Product Lines — Chromebook + Radius + Fusion
This is the only Toshiba battery in this capacity class that serves Chrome OS, Windows 2-in-1 convertible, and standard touchscreen form factors under a single part number. School IT departments managing CB35 Chromebooks alongside Satellite Radius Windows devices can consolidate both into a single battery SKU — something most procurement teams don’t know is an option until they check the label.
✅ 🧬 Li-Polymer Cell Chemistry — Required for the 360-Degree Hinge Chassis
The Satellite Radius and Fusion convertible series use flat Li-Polymer cells, not cylindrical 18650 Li-ion. The slim 360-degree hinge chassis physically cannot accommodate a standard cylindrical cell pack. Our replacement follows the same laminated pouch cell construction as the OEM unit. Anti-swell BMS logic is included — original Toshiba Li-Polymer packs on this generation are prone to heat-induced cell expansion after several years; our replacement uses stabilized polymer chemistry to reduce that risk.
✅ 📚 Education Fleet Procurement — CB35 Bulk Supply
The Toshiba Chromebook 2 (CB35-B3330, CB35-B3340) was deployed in meaningful volume across North American school districts from 2014 through 2017 under 1:1 device programs. These devices are still in active use in many districts — battery degradation is the primary reason they get retired early. Bulk supply of PA5208U-1BRS for school IT refresh programs is a direct application; we can structure orders to match maintenance cycle timelines.
✅ ⚠️ The P55W-B vs. P55W-C Distinction — Buy the Right One
Toshiba sold the Satellite P55W in two hardware generations: the B-series (PA5189U-1BRS, 14.4V / 60Wh) and the C-series (PA5208U-1BRS, 10.8V / 45Wh). The voltage difference is significant — installing a 10.8V pack in a 14.4V system, or vice versa, will result in charge failure and a battery-not-recognized error. The suffix on the machine model (P55W-B vs. P55W-C) is the fastest way to confirm which generation you have before ordering. If you’re unsure, check the original battery label directly: P000619700 or P000645710 means C-series; PA5189U-1BRS means B-series.
✅ 🛡️ Active Protection Circuit with ESD and Thermal Monitoring
Overcharge cutoff, over-discharge floor, overcurrent limit, short-circuit shutdown, ESD protection, and NTC thermal monitoring — all active in hardware. The BMS is factory-programmed to communicate with Toshiba’s host system. No unknown device warnings, no charge errors, no calibration cycle required on first use beyond standard factory charge conditioning.

Häufig gestellte Fragen
Q1: Does this battery fit both the Toshiba Chromebook CB35 and the Satellite Radius 15 P55W — those are completely different machines. How is that possible?
A: Toshiba’s engineering team used the same internal battery bay, connector, and cell specification across the CB35 Chromebook, the Satellite Radius 14 (E45W / L40W), Satellite Radius 15 (P55W-C / P50W-C), and Satellite Fusion 15 (L55W-C) platforms. The operating system — Chrome OS vs. Windows — does not affect battery compatibility; the electrical interface is identical. This is a genuine OEM design decision, not a coincidence, and it means one SKU covers all four product lines.
Q2: My machine is a Toshiba Satellite P55W. How do I know if it’s the B-series or C-series, and does it matter?
A: It matters significantly — the two series use completely different batteries at different voltages. Check the model number sticker on the bottom of your machine. If it reads P55W-B (e.g., P55W-B5224), it requires the PA5189U-1BRS (14.4V / 60Wh) — not this battery. If it reads P55W-C (e.g., P55W-C5204, P55W-C5208, P55W-C5314), the PA5208U-1BRS is the correct fit. If you cannot access the bottom label, open the back panel and check the original battery label directly: P000619700 or P000645710 confirms the C-series / PA5208U-1BRS application.
Q3: We manage a fleet of Toshiba Chromebook CB35s in a school district. Can we order bulk replacement batteries for a maintenance program?
A: Yes, and this is a common procurement scenario for districts still running CB35-B3330 and CB35-B3340 devices. Battery degradation — typically appearing 3–5 years after original deployment — is the most common reason these units get flagged for replacement rather than continuing service. Bulk orders are available with volume pricing; contact us via the wholesale inquiry form with your device count and preferred delivery schedule.
Q4: Why does this battery use Li-Polymer and not standard cylindrical Li-ion cells?
A: The Satellite Radius and Fusion convertible chassis uses a 360-degree hinge design that requires a flat profile battery. Cylindrical 18650 cells cannot physically fit the battery bay in these thin 2-in-1 machines. Li-Polymer (flat laminated pouch cells) is the only cell chemistry compatible with this chassis. Additionally, Li-Polymer cells are less prone to leakage than cylindrical cells when properly managed — relevant for the 360-degree stress cycles a convertible machine experiences.
Q5: Can I order a sample unit before committing to a bulk order?
A: Yes. Sample orders are available for school district procurement officers, repair chain buyers, and IT distributors. Typical lead time is 3–5 business days. Submit an inquiry via the wholesale contact form with your organization name, device model, and estimated order volume.
Q6: My Toshiba Chromebook CB35 shows a battery not recognized warning after installing a replacement. What is the likely cause?
A: On Chrome OS devices, this warning most commonly results from an incomplete connector seating rather than a firmware or BMS mismatch. Power off the machine, disconnect and firmly reseat the battery connector — the multi-pin flat cable on the CB35 platform requires full positive engagement to establish the BMS handshake. If the warning persists after reseating, perform a hard reset (hold Refresh + Power for 3 seconds) and reconnect the charger. Our units are factory-programmed for Chrome OS BMS compatibility; persistent warnings after reseating indicate a connector issue rather than a battery defect.
