VGP-BPS13 11.1V 48.84Wh Sony VAIO VGN-AW VGN-CS VGN-FW VGN-SR Series Replacement Battery — Black & Silver | Manufacturer-Stock Wholesale

Q1: Does this battery work with both 10.8V and 11.1V VGN-series machines, and will the VAIO power tray display voltage correctly?

Yes. Sony’s VAIO firmware treats 10.8V and 11.1V as equivalent nominal voltages — the embedded controller does not differentiate between them and will not generate a voltage mismatch warning. The actual cell chemistry in both cases is Li-Ion with a nominal cell voltage of approximately 3.6–3.7V per cell; the 10.8V / 11.1V difference is a labeling convention rather than a functional distinction. Our BMS is configured to Sony’s charge termination and discharge floor parameters, so the battery reports normally in VAIO’s power management interface across all VGN and VPC platform variants covered by this P/N.

Q2: The VGN-FW and VGN-SR use different chassis designs — will the latch and connector seat correctly on both?

Yes. Sony held the battery bay geometry — including the slide-latch position, connector orientation, and housing footprint — constant across the VGN-FW, VGN-CS, VGN-AW, and VGN-SR chassis families despite the visual differences between them. The dimensional difference is in the chassis top cover and display assembly, not the battery compartment. Our housing is injection-molded to the same 204.20 × 47.10 × 20.60mm specification as the original OEM pack, with a ±0.3mm tolerance on all critical dimensions. Both latch engagement points are verified on representative chassis during batch approval.

Q3: We service a mixed Sony VAIO inventory — can we order black and silver units in the same purchase order, and is there a minimum quantity per color?

Yes, mixed-color orders are processed as a single purchase order. We do not require separate orders by color or impose a per-color minimum above the overall order MOQ. Both black (VGP-BPS13/B) and silver (VGP-BPS13/S) are held in manufacturer stock — not produced to order — so they ship together from the same dispatch. If your operation also needs higher-capacity units for specific jobs, 5200mAh 6-cell and 6600mAh 9-cell variants can be included in the same order as custom-build line items; lead time for those variants is typically 7–14 business days from order confirmation.

Q4: The 6600mAh 9-cell version extends past the bottom of the laptop — does that affect heat dissipation or the structural integrity of the latch?

The 9-cell pack protrudes approximately 25mm below the battery bay floor, which is a design feature rather than a tolerance issue — the extended section adds cell volume while the forward latch engagement remains identical to the 6-cell version. In terms of heat: the additional cell mass and increased surface area exposed below the chassis actually improves passive dissipation relative to the flush 6-cell pack, which sits fully enclosed in the bay. The extended protrusion does raise the rear of the machine slightly, which can improve underside airflow depending on surface type. The connector and data-line pinout are identical across all three capacity variants.

Q5: How should we handle VGP-BPS13 units that will sit in workshop stock for 30–60 days before being fitted to machines?

Store at 40–60% state of charge in a dry, temperature-stable environment between 10°C and 25°C. We ship all units at approximately 50% SOC to align with the optimal lithium-ion storage window — full-charge storage accelerates cathode degradation and is the primary cause of capacity loss in shelf-stock batteries. For units held longer than 60 days, we recommend a single conditioning cycle before fitting: charge fully, then discharge to the laptop’s low-battery cutoff point. This re-calibrates the BMS fuel gauge and confirms the cell stack is performing within specification before the unit reaches the end customer.

Q6: What UN38.3 documentation is available, and does it cover both the black and silver variants under a single test report?

UN38.3 testing covers the electrochemical and mechanical properties of the cell pack — voltage, capacity, cell chemistry, and BMS cutoff parameters — which are identical across both color variants. The housing color difference is a cosmetic distinction with no bearing on the test criteria. A single UN38.3 test summary therefore covers both black and silver units under this P/N. We can provide the UN38.3 test summary, CE Declaration of Conformity, RoHS certificate, and MSDS/SDS records as a combined compliance package on request. These are available at the purchase order stage and are included as standard documentation with all volume shipments requiring air freight or customs declaration.
