Replacement battery for Sony Vaio Flip

The PISKEKAT VGP-BPS40 is a 15V 3170mAh 48Wh lithium-ion battery built for Sony Vaio Flip SVF14A, SVF14N, SVF15A and SVF15N series laptops. It replaces part numbers VGP-BPS40, VGPBPS40 and BPS40. The pack arrives new from the manufacturer and is rated for up to 500 recharge cycles over its service life. It is not suited for owners of other Sony models or non-Vaio ultrabooks.

Thermals noise and power in daily use

As an internal battery it produces no audible noise and adds no active cooling load to the system. Normal operation draws power at the rated 15V with a 48Wh capacity that supports typical mobile workloads. The black lithium-ion cell maintains stable voltage during standard office tasks and media playback. No external power adapter is included with this unit.

Behaviour under sustained load

After the initial 3-4 charge and discharge cycles taking roughly 7-8 hours the lithium-ion chemistry reaches its full usable capacity. Continuous heavy use will deplete the 48Wh reserve proportionally to the laptop's power draw while the cell chemistry handles repeated cycling up to the 500-cycle rating. Runtime scales directly with the workload intensity of the host device.

The 500-cycle rating is the first hard limit; once reached the capacity degrades and the battery must be replaced.
