PA3817U-1BRS 10.8V 48Wh Toshiba Satellite C655 L755 Series Battery — Wholesale Stock

Q1: Several PA3817U-1BRS cross-references carry different suffix letters — does the suffix letter on the original battery label indicate which cell manufacturer was used in the OEM pack?

A1: On the PA3816U through PA3819U family, the numeric suffix (1BRS, 1BAS, 1BAP) identifies the pack chemistry grade and regional documentation variant, not the cell manufacturer source. The “BRS” designation indicates a standard Li-ion replacement pack; “BAS” is the authorized service variant used in Toshiba’s regional service parts programs. Neither suffix reliably identifies the OEM cell supplier across the full production run — Toshiba used multiple cell sources across C655 and L750/L755 production years. For sourcing purposes, all suffix variants within PA3816U–PA3819U are electrically and mechanically identical and resolve to a single battery position on the production line.

Q2: The Satellite L770 and L775 are 17-inch chassis — does the PA3817U-1BRS physically fit these larger platforms without modification?

A2: The PA3817U-1BRS fits the L770 and L775 battery bay without modification. Toshiba maintained the same battery bay geometry and connector position across 15-inch and 17-inch Satellite L-series chassis from this production era — the larger footprint of the L770 and L775 chassis does not extend to a longer battery cavity. The battery connector position, locking rail geometry, and PCB tab orientation are identical between the L755 and L775 battery bays, confirmed across service documentation for both chassis families. L770D and L775D variants use the same position.

Q3: Does the PA3817U-1BRS cover the Dynabook B351 series used in Japanese education deployments — or does that platform require a separate Dynabook-specific P/N?

A3: The Dynabook B351 uses the same battery bay geometry and SMBus connector pinout as the Satellite L-series from the same production period. Toshiba’s Japanese domestic B351 education model was built on the same chassis platform as the global Satellite L750/L755, sharing battery cavity dimensions and BMS communication protocol. PABAS228 and PABAS229 — both within this stock line — appear in Dynabook’s own service documentation for B351 series units. A depot or institutional buyer servicing a Japanese-market B351 fleet does not need a separate Dynabook-specific sourcing line; this P/N covers those units directly.

Q4: After installing PA3817U-1BRS, Toshiba’s PC Health Monitor displays a battery replacement advisory even though the battery is new — what causes this and how is it cleared?

A4: The PC Health Monitor advisory at installation reflects an SMBus design capacity mismatch — the EC compares the BMS-reported design capacity against the baseline stored from the original OEM battery and flags any divergence as a degraded state. Because the BMS firmware on this production unit declares design capacity at 4400mAh, matching the factory OEM SMBus profile, this advisory should not appear. If it does — typically on units where the EC stored a non-standard baseline from a prior aftermarket battery — perform a full EC reset: power off, disconnect AC, remove the battery, hold the power button for 30 seconds, reinsert the battery, and charge to 100% before running the first discharge cycle. This re-initializes the EC’s health baseline against the new battery’s SMBus data and clears the advisory on subsequent Health Monitor polls.

Q5: We want to place an initial stocking order for PA3817U-1BRS alongside several Dell and Lenovo battery SKUs — can we combine everything on one order, and what is the process?

A5: Mixed-brand orders are handled on a single purchase order without requiring separate submissions per brand. Confirm the PA3817U-1BRS quantity alongside your Dell and Lenovo SKUs, and submit the full list with target quantities — we will return a consolidated price sheet covering all lines with a single lead time confirmation. For first-time orders, sample units are available prior to volume commitment; state your sample requirement when submitting the initial list so we can include it in the same shipment.

Q6: What documentation is included with PA3817U-1BRS wholesale shipments for customs clearance — specifically for buyers importing into the EU or North America?

A6: Each wholesale shipment of PA3817U-1BRS includes a UN38.3 test summary, CE declaration of conformity, RoHS compliance declaration, and a commercial invoice with HS code 8507.60.0090 declared. The UN38.3 documentation covers the full 8-test sequence for Li-ion cells and assembled packs, which satisfies IATA dangerous goods requirements for air freight and the documentation standard required by EU customs for lithium battery imports. For North American imports, the CE and RoHS declarations satisfy standard broker requirements; buyers requiring additional documentation (MSDS, packing declaration, or country-of-origin certificate) should specify at the time of order so these are prepared with the shipment rather than requested after dispatch.
