Product Description
The Toshiba Satellite C55 and L55 families shipped in enormous volumes between 2013–2016, targeting the education and budget enterprise market. Millions of these units remain in active service across school districts, SMB fleets, and refurbishment pipelines. The factory original battery — Toshiba part number PA5185U-1BRS (also printed as P000602600 on OEM units) — is no longer widely stocked by Toshiba’s distribution channels, which makes aftermarket supply the only practical procurement path for most IT buyers.
This is an internal, non-removable battery, a design shift from the older C55-A generation (which used the external PA5109U). Buyers ordering for mixed Satellite fleets should confirm their units are C55-B, C55-C, or L55-B generation before ordering.

Features & Advantages
✅ 🔋 True 45Wh Capacity — No Inflated Specs
Rated at 14.8V / 45Wh (2800mAh) actual measured output. Market is flooded with 2200mAh units mislabeled as 45Wh — those are 32Wh at best. Our spec sheets match what ships. For repair shops billing customers on runtime guarantees, the difference is real.
✅ 🔌 Voltage Label Discrepancy — Explained
Some OEM units show 14.4V on the battery label; ours ships as 14.8V. Both are correct for a 4-cell series Li-ion pack — nominal vs. average charge voltage. Toshiba’s BMS firmware on all C55-B / L55-B systems accepts the full 14.4V–14.8V window without triggering charge errors.
✅ 🏭 Factory-Direct Supply Chain for B2B Buyers
No distributor markup. IT procurement teams and repair wholesalers can consolidate Toshiba Satellite battery SKUs under a single purchase order covering C55, L55, and S55 fleets simultaneously, since all three lines share this footprint.
✅ 🛡️ Multi-Layer Protection Circuit
Built-in PCB guards against overcharge, over-discharge, overcurrent, short circuit, and overtemperature. No BMS bypass or wake-up procedure required out of box — install, connect charger, done.
✅ 📦 Bulk-Ready Packaging for Resellers
Each unit ships in individual anti-static packaging. Case quantities are available for distributors requiring shelf-ready retail packs or plain brown-box OEM style — specify at inquiry stage.

FAQ
Q1: Does the PA5185U-1BRS fit Toshiba Satellite C55-A models?
A: No. The C55-A uses an external, removable battery (PA5109U-1BRS). The PA5185U-1BRS is a slim internal battery designed exclusively for the C55-B, C55-C, L55-B, L55-C, and related “slim chassis” generations. Ordering for a C55-A using this part will result in a mismatch.
Q2: My original battery label says 14.4V — is a 14.8V replacement safe?
A: Yes, completely. Both 14.4V and 14.8V describe the same 4-cell series Li-ion architecture — 14.4V is nominal average, 14.8V is the standard rated voltage. Toshiba’s charge management firmware for all affected Satellite models is designed to handle this range. No compatibility issues, no charge errors.
Q3: What is the realistic runtime I should advertise to my repair customers after replacement?
A: Under normal office workloads (web browsing, documents, ~50% screen brightness), a fresh 45Wh cell in a C55-B or L55-B delivers approximately 2.5–3.5 hours. Customers running higher-load tasks (video playback, multiple apps) should expect 1.5–2.5 hours. Setting this expectation upfront prevents post-sale disputes.
Q4: What cross-reference part numbers are confirmed compatible with this battery?
A: PA5184U-1BRS, PA5185U-1BRS, PA5186U-1BRS, PA5195U-1BRS, G71C000HW110, G71C000J110, G71C000J7510, and Toshiba OEM assembly number P000602600. All are physically interchangeable within the confirmed model list.
Q5: Can I order samples before committing to a bulk purchase?
A: Yes. Sample orders are available for qualified buyers — repair chain buyers, IT procurement officers, and distributors. Lead time for samples is typically 3–5 business days. Contact us directly via the inquiry form with your business name and intended volume.
Q6: What is the warranty and what does it cover for wholesale orders?
A: All units carry a 12-month warranty covering manufacturing defects, capacity failure below 80% under normal charge cycles, and BMS/PCB faults. DOA rate on bulk shipments is tracked per order; replacement or credit is issued without requiring full return shipment for confirmed DOA units.
