It depends on the exact Vaio model, since Sony used proprietary VGP packs matched to each chassis. Two of the most common in this category are the VGP-BPS22/B (found in VPC-EB and VPC-EC machines) and the VGP-BPS38 (used in slimmer S-series models). These are lithium-ion, run between 7.5 and 11.1 V, and deliver about 57 Wh. Check the model number on your laptop base or the part number on your current battery, then match it before you buy. Replacements in this line run $64.99 to $68.99.

Match by your full model number or the part number printed on your old battery. The model number sits on a label on the bottom of the laptop (for example VGN-FW139E or VPC-EB1JFX), and the part number is on the battery itself in VGP-BPSxx form, like VGP-BPS22/B. Because Sony used 7 distinct part numbers across roughly 256 Vaio models, the exact match matters. Cross-check both numbers against the listing, since similar-looking models often take different packs.

Vaio replacement batteries in this category run $64.99 to $68.99. The price reflects lithium-ion construction, capacity around 57 Wh, and voltage between 7.5 and 11.1 V. Cost stays consistent across the 7 part numbers we carry, so a VGP-BPS22/B and a VGP-BPS38 fall in the same range. Confirm your exact model number first so you buy the pack that fits your chassis rather than choosing on price alone.

No, not across the board. Sony built proprietary VGP packs for specific chassis, so a battery from one sub-series usually will not fit another. For example, the VGP-BPS22/B used in VPC-EB models is not the same as the VGP-BPS38 used in slimmer S-series machines, even though both are lithium-ion in the 7.5 to 11.1 V range. Always verify the part number printed on your old battery before assuming two packs are compatible.

The main differences are cell count, physical shape, and connector layout tied to each chassis. Sony used 6-cell and 9-cell lithium-ion designs across the VGN and VPC generations, all roughly 57 Wh and 7.5 to 11.1 V, but the housings differ so they fit only their intended models. That is why we list 7 distinct part numbers like VGP-BPS22/B and VGP-BPS38 for about 256 models. The electrical specs stay close while the form factor and part number change.

Look on the battery itself, where Sony prints the VGP-BPSxx code (for example VGP-BPS22/B or VGP-BPS38). On most Vaio models the battery attaches to the back or bottom, so you may need to release it to read the full label. If you cannot remove the pack, use your laptop model number from the base label (such as VPC-EB1JFX) to cross-reference. Either number lets you match against our 7 part numbers covering around 256 models.

Yes, on many Vaio models the battery is a user-serviceable pack mounted to the back or bottom and held by release latches, so it comes off without tools. Slide the latch, lift the old pack, and seat the new one until it clicks. Some later slim S-series designs are more integrated and take more effort. Match the part number first (for example VGP-BPS22/B or VGP-BPS38) so the replacement seats correctly and lines up with the contacts.

Watch for sharply reduced runtime, a battery that drains in minutes, failure to hold a charge, or a laptop that shuts off when unplugged. You may also see the system stay at a fixed charge percentage or report the battery as not detected. These point to worn lithium-ion cells, common in older Vaio packs. A fresh replacement in the 7.5 to 11.1 V, roughly 57 Wh range, such as a VGP-BPS22/B, restores normal runtime. Confirm your part number before ordering.
