Replacement battery for Sony Vaio AR NR SZ CR series
This 11.1V 5200mAh lithium-ion pack replaces VGP-BPS9 and VGP-BPL9 part numbers across the listed Sony Vaio models. It is a new 6-cell unit rated at 58Wh for owners of compatible PCG-series laptops who need a direct-fit replacement. Buyers with different Sony series or non-Sony laptops cannot use this battery.
Sustained discharge and cycle life
The pack delivers its rated capacity through overcharge, overdischarge, over-temperature and short-circuit protection circuits that keep output stable during long sessions. Cells are specified for up to 500 recharge cycles over the life of the battery while meeting OEM electrical standards.
Installation and common issues
Installation is a standard battery-bay swap on the supported Vaio models; no tools beyond a screwdriver are typically required. The silver casing matches the original colour. The most frequent issue is ordering the wrong part number, so verify your laptop model or OEM part code against the compatibility list before purchase.

Questions about this item
Does the 11.1V 5200mAh battery run hot or make noise during all-day use?
The 6-cell lithium-ion pack has built-in over-temperature and short-circuit protection, so it stays cool and silent under continuous load.
What must my Sony Vaio already have for this VGP-BPS9 replacement to fit?
Your laptop must use one of the listed part numbers such as VGP-BPS9, VGP-BPL9 or VGP-BPS9A/B and be a compatible model like PCG-7111L or PCG-7131L.
Will this 58Wh pack work alongside the original AC adapter I kept from my older Vaio?
Yes, the 11.1V output matches the OEM specification, so the existing charger will charge the battery normally.
