Сменный аккумулятор VGP-BPS26 11,1 В 59 Вт·ч для Sony VAIO VPC-CA VPC-CB серии SVE — оптовая поставка напрямую от производителя.

Q1: Will this battery trigger a “battery not detected” or power-management error on VAIO hardware?

No — and this is the specific failure mode we engineer against on the VGP-BPS26. Sony VAIO VPC and SVE platforms communicate battery state through SMBus over the 7-pin connector. If the BMS EEPROM does not carry the correct device chemistry code and charge-profile registers, the embedded controller either refuses to charge or reports an error in the VAIO power management tray. We pre-flash each pack with parameters mapped to Sony’s original EC specification. In production testing, we validate EC handshake on a VPCEH reference unit before approving each batch for shipment.

Q2: Some SVE-series machines show battery “wear” percentage immediately after a new pack is installed — is that normal with this replacement?

Yes, and it reflects how Sony’s firmware reads the cycle-count register rather than a fault in the battery. Sony VAIO SVE firmware initializes the wear percentage from the BMS cycle-count register at first recognition. If the register reports a non-zero value from our QA cycling process, the OS may display a small wear offset — typically 1–3%. This does not affect runtime or charge capacity. For buyers deploying at volume, we can ship packs with the cycle-count register zeroed to factory state on request; specify this at the order stage.

Q3: OEM VGP-BPS26 stock is listed as discontinued — how do you ensure continued supply availability?

Sony discontinued VGP-BPS26 production through its service parts channel several years ago. We maintain this part number as a dedicated EOL buffer line because demand from the independent repair market remains measurable and persistent. We hold forward inventory based on 90-day rolling order data. For distributors or repair operations with predictable monthly volume, we offer blanket-order terms that reserve allocated stock — this removes the spot-sourcing uncertainty that comes with relying on secondary market channels or irregular surplus lots. Contact us for volume pricing and allocation schedules.

Q4: The VPC-CA and VPC-EH use different chassis widths — does this single part number physically fit both?

Yes. Sony standardized the battery bay dimensions and latch-tab geometry across the full 2011 VAIO consumer platform despite the chassis width differences between the 14-inch VPC-CA and the 15.5-inch VPC-EH. The battery pack footprint, connector orientation, and both latch positions are identical across VPC-CA, VPC-CB, VPC-EG, VPC-EH, VPC-EJ, and VPC-EL variants. The dimensional tolerance on our injection-molded housing is held to ±0.3mm, which keeps latch engagement within Sony’s original retention spec.

Q5: What is the recommended storage protocol if we receive a volume order and hold units in inventory for 60–90 days before deployment?

Store at 40–60% state of charge in a dry environment between 10°C and 25°C. At 100% charge, lithium-ion cells under storage conditions experience accelerated cathode oxidation — this is the primary cause of capacity loss in units that arrive “fully charged” and sit on a shelf. We ship all units at approximately 50% SOC specifically to align with the optimal storage window. For inventory held beyond 90 days, a single conditioning cycle — full charge followed by a full discharge — is sufficient to verify capacity before deployment.

Q6: Is this battery compliant with UN38.3 for air freight? What documentation is available?

Yes. All VGP-BPS26 units we manufacture are tested to UN38.3 (the United Nations transport safety standard for lithium cells and batteries), which is the required certification for air freight of lithium-ion batteries as cargo. We can provide the UN38.3 test summary, MSDS/SDS documentation, and CE/RoHS certification records for customs and freight compliance purposes. These documents are available on request at the order stage and are included as standard with any volume shipment that requires declaration paperwork.
