Most Sony SVT laptops use an internal lithium-ion pack rated around 11.1V or 11.4V. The 11.6-inch SVT11 and 13.3-inch SVT13 models commonly take the VGP-BPS30, while later 13.3-inch and the larger 15.5-inch SVT151 models often use the VGP-BPS33. Because the same series spans three chassis sizes and multiple model years, the correct pack depends on your exact model. Check the part number printed on your old battery to confirm. Replacement batteries in this category run $75.99.

Match your exact model number, which is printed on a label on the bottom of the laptop (for example, SVT13112FXS). You can also read the VGP-BPS part number directly off your current battery. The 11.6-inch and most 13.3-inch units use VGP-BPS30, while later 13.3-inch and 15.5-inch models often use VGP-BPS33. Confirming both the model number and the printed part number is the surest way to avoid ordering the wrong size or voltage.

A Sony SVT replacement battery is priced at $75.99 in this category. Cost can depend on the sub-series, since the 11.6-inch SVT11 and 13.3-inch SVT13 take the VGP-BPS30 while the larger 15.5-inch SVT151 often needs the higher-capacity VGP-BPS33. Confirm your exact model number before buying so you pay for the pack that actually fits your chassis rather than one built for a different size.

Not always. While many 11.6-inch and 13.3-inch models share the VGP-BPS30, later 13.3-inch units and the 15.5-inch SVT151 frequently use the VGP-BPS33, which is a different capacity. A pack from one sub-series will not necessarily fit or seat correctly in another. The voltage runs around 11.1V or 11.4V across the line, but physical size and part number still vary. Always verify your model number and the part number on your old battery before assuming two packs are compatible.

The main differences are chassis size and capacity. The SVT11 (11.6-inch) and SVT13 (13.3-inch) typically use the VGP-BPS30, a more compact pack suited to those thinner bodies. The SVT15 (15.5-inch, often the SVT151 touchscreen model) usually needs a larger, higher-capacity battery such as the VGP-BPS33. Voltage stays around 11.1V or 11.4V across all three, but the physical dimensions and part number change with the model size and year.

The part number is printed directly on your current battery, formatted as a VGP-BPS code such as VGP-BPS30 or VGP-BPS33. On the SVT series the battery is internal, so you open the bottom chassis with a small Phillips screwdriver to read the label. You can also note your laptop’s model number from the underside label (for example, SVT13112FXS). Having both the model number and the VGP-BPS code makes confirming the correct pack straightforward.

Yes, with a small Phillips screwdriver. The SVT series uses an internal pack, so you remove the screws on the bottom panel, lift the chassis cover, disconnect the old battery, and seat the new one (commonly a VGP-BPS30 or VGP-BPS33). Work slowly so you do not strain the connector or cables. Match the part number to your exact model first, since the 11.6-inch, 13.3-inch, and 15.5-inch versions can use different packs around 11.1V or 11.4V.

Watch for sharply reduced runtime, the laptop shutting off well before reaching zero percent, or charge readings that jump erratically. If the system only runs while plugged in or no longer holds a charge, the internal pack is likely worn. Since these lithium-ion batteries (around 11.1V or 11.4V) age with cycle use, a years-old SVT often shows these symptoms. When you order a replacement, confirm whether your model takes the VGP-BPS30 or VGP-BPS33. Replacements run $75.99.
