Replacement battery for Sony VAIO 2011 series

The PISKEKAT BPS26 is a new 11.1V 58Wh lithium-ion pack built with six Grade A cells. It matches the original VGP-BPS26 and VGP-BPL26 form factor so it fits CA, CB, EG, EH, EJ and EL series notebooks from 2011 without modification. Owners of those models can restore mobile runtime with a direct swap.

Thermals and power behaviour

Grade A cells are specified for fast charging and low self-discharge, keeping heat output modest during normal charge cycles. Built-in circuit protection guards against over-charge, over-discharge and short-circuit events, which helps maintain stable voltage under typical office or web-browsing loads. The pack is rated for up to 600 recharge cycles over its service life.

Build quality and daily use

CE, RoHS and FCC certifications confirm compliance with electrical safety and substance restrictions. The housing replicates the OEM dimensions exactly, so the battery locks into the existing bay without gaps or forced alignment. No extra cables or adapters are required; the original charger continues to work as before. Buyers needing a higher capacity than 58Wh or a different voltage should look elsewhere.

Questions about this item

How do I install the BPS26 battery and what step is often missed?

Power off the laptop, remove the AC adapter, slide the release latch, swap the old pack for the new 6-cell BPS26, then charge it fully before first use to calibrate the fuel gauge.

What maintenance or replacement will the BPS26 need later?

The 58 Wh pack is rated for up to 600 recharge cycles; after that capacity drops noticeably and a replacement battery will be required.

What limit appears first during sustained use of the BPS26?

The built-in circuit protection will cut output if current or temperature exceeds safe thresholds, so thermal or current limits trigger before the 58 Wh capacity is fully drained.
