VGP-BPS24 11.1V 49Wh Sony VAIO VPC-SA VPC-SB VPC-SC VPC-SD SVS13 SVS15 Series Replacement Battery — Manufacturer-Stock Wholesale

Q1: Will this battery support Sony’s Battery Care Function charge-limit settings on VPC-SB and SVS13 machines?

Yes — and this is a specific BMS implementation requirement we treat as a primary QA criterion for this P/N. Battery Care Function operates over SMBus: the embedded controller sends a charge-ceiling command (50% or 80% cap) to the battery BMS, which must recognize and act on it. Aftermarket packs that do not implement this command set allow the battery to charge to 100% regardless of the user’s settings. We flash the charge-ceiling command handler into the BMS firmware and verify its response on a VPC-SB reference unit during batch sign-off. For repair centers and distributors, this means the end customer’s power management configuration works as originally designed — not silently overridden.

Q2: Some VPC-SE sub-variants shipped with different chassis finishes — does this affect which battery fits, or is VGP-BPS24 universal across all VPC-SE variants?

VGP-BPS24 is universal across the full VPC-SE range. Sony differentiated VPC-SE sub-variants through processor tier, display resolution, and regional market suffix, but the internal battery bay dimensions, blade connector type, screw-retention positions, and battery shut-off switch configuration are consistent across all VPC-SE sub-models. Chassis finish color has no bearing on battery compatibility — the battery is fully internal and not visible from outside the machine. The same physical pack that fits a VPCSE1E1E fits a VPCSE2V9E without modification.

Q3: We stock multiple Sony VAIO P/Ns — how does VGP-BPS24 relate to BPS22 and BPS26, and can inventory be consolidated?

These are distinct and non-interchangeable P/Ns for different Sony VAIO platform generations. VGP-BPS26 covers the 2011 VPC-CA/CB/EG/EH/EJ/EL platform (external snap-in, 11.1V/59Wh). VGP-BPS22 covers the 2010–2012 VPC-EA/EB/EC/EE/EF platform (external snap-in, 11.1V/58Wh). VGP-BPS24 covers the 2011–2013 VPC-SA/SB/SC/SD/SE and SVS13/SVS15 platform (internal blade-connector mount, 11.1V/49Wh). Connector type, bay geometry, and mounting method differ across all three — they cannot be substituted for each other. Each requires a separate inventory line. We supply all three P/Ns and can structure a combined volume order across multiple Sony P/Ns for distributors managing full Sony VAIO catalog coverage.

Q4: What does the battery shut-off switch on some VPC-S sub-models do, and does it affect the battery you supply?

Certain VPC-SA and VPC-SB sub-variants include a small physical switch near the battery connector on the motherboard that cuts power from the battery to the board — it is a manufacturing protection feature to prevent short circuits during service. If this switch is left in the “off” position after reassembly, the machine will not draw power from the battery even with a fully charged pack installed, producing a symptom that looks identical to a dead battery. Our installation note included with each unit identifies this switch location and the correct orientation for normal operation. The switch is a chassis feature, not something the battery itself controls — it works the same way with our pack as it did with the original.

Q5: What storage conditions apply to VGP-BPS24 units held in parts inventory before installation?

Store at 40–60% state of charge in a dry environment between 10°C and 25°C. We ship all units at approximately 50% SOC, placing them within the optimal lithium-ion storage window from the point of receipt. At full charge, the cathode of a 6-cell Li-Ion pack remains under elevated electrochemical stress during storage, which is the primary driver of capacity loss in shelf-stock batteries regardless of brand. For units held beyond 60 days, a single conditioning cycle before installation — charge to full, then allow normal discharge to the low-battery cutoff — resynchronizes the BMS fuel gauge register with the actual cell stack condition.

Q6: Is UN38.3 certification for this battery valid across all destination markets, and does the internal-mount design affect transport classification?

UN38.3 certification applies to the electrochemical and mechanical properties of the lithium-ion cell pack itself — it is not affected by whether the battery is an external snap-in or an internal blade-connector design. The classification under IATA dangerous goods regulations for air freight depends on Wh rating and packaging condition, not installation method. At 49Wh, this pack falls within the standard Section II threshold for lithium-ion batteries shipped as cargo, which simplifies documentation relative to packs above 100Wh. We provide the UN38.3 test summary, CE Declaration of Conformity, RoHS certificate, and MSDS/SDS records as a combined compliance package at the purchase order stage, available in advance of shipment for freight forwarder pre-declaration.
