SKU CH-JKY7-97T7K

Replacement 11.1 V 5200 mAh 6-cell lithium-ion battery for compatible Sony Vaio laptops with overcharge, overdischarge and temperature protection

  • Longer runtime with 5200mAh capacity and 11.1V output
  • Reliable power from six lithium-ion cells
  • Safe charging via overcharge, overdischarge and temperature protection
  • Broad compatibility with many Sony Vaio models and part numbers

Replacement battery for Sony Vaio

The kolitt BPS9 is a new lithium-ion battery built for the listed Sony Vaio PCG models. It operates at 11.1V with a 6-cell layout and includes overcurrent, overcharge, overdischarge, over-temperature and short-circuit protection. The pack meets OEM specifications and is rated for up to 500 recharge cycles.

5200mAh capacity with 4400mAh rating

The battery offers a 5200mAh capacity alongside a 4400mAh rating at 11.1V, delivering extended runtime for everyday office work, web browsing and media playback. Heavy workloads such as sustained video rendering or gaming will deplete the charge faster, so users who need all-day power away from a socket should plan for a recharge or a spare pack.

Direct swap for BPS9 and VGP-BPS9 part numbers

This unit replaces original part numbers including BPS9, VGP-BPL9, VGP-BPS9, VGP-BPS9/B, VGP-BPS9/S, VGP-BPS9A and VGP-BPS9A/B. The upgrade is worthwhile when the original pack no longer holds a useful charge or has swollen, restoring mobility without changing the laptop. Buyers whose model is not in the compatibility list should look for a different battery.

Questions about this item

Will the 11.1 V 5200 mAh Li-ion pack run safely in my Sony Vaio PCG-7131L that originally used a VGP-BPS9A/B battery?

Yes, the cell voltage and capacity match the OEM specification and the built-in overcharge, overdischarge, over-temperature and short-circuit protection circuits keep the laptop operating within its original power envelope.

How can I confirm the battery is charging and reporting capacity correctly after I install it?

After fitting the pack, boot the Vaio and check the Windows battery icon — it should show a charging animation, then report a design capacity close to 5200 mAh and cycle count starting near zero.

Does the box include a replacement AC adapter or just the 6-cell battery itself?

Only the 6-cell Li-ion battery is supplied; the original AC adapter must be reused or purchased separately.
