Replacement battery for Dell Studio 15 series

This 9-cell lithium-ion unit replaces the original Dell Studio 1535 and 1558 batteries. It fits models carrying part numbers PP39L, MT264 and WU946 and matches the OEM physical dimensions. The pack is brand new and certified to CE, RoHS and FCC standards.

Extended capacity under continuous use

Rated at 7800 mAh and 11.1 V, the battery delivers longer run-time than standard 6-cell packs during sustained workloads. Integrated circuit protection guards against over-charge, over-discharge and short circuits throughout each cycle. Cells are rated for up to 600 recharge cycles over the service life.

Voltage compatibility decides fit

The pack operates at 11.1 V and is also compatible with 10.8 V systems, so the laptop must accept this voltage range. Buyers whose machines require a different voltage cannot use this unit.

Questions about this item

How much heat does the 9-cell 7800 mAh 11.1 V battery generate during all-day use?

The lithium-ion pack runs at 11.1 V (10.8 V compatible) and is rated for up to 600 recharge cycles; normal operation produces only modest warmth thanks to built-in circuit protection.

What must I already own so the WU946 MT264 PP39L battery fits and works?

A Dell Studio 1535, 1536, 1537, 1555, 1557 or 1558 laptop that originally used a PP33L or PP39L battery; the replacement has the same size and shape as the OEM pack.

Will the 9-cell extended battery work alongside the original 6-cell charger and BIOS on my Studio 1535?

Yes — the 11.1 V (10.8 V compatible) pack is designed to the same electrical spec as the factory battery, so the existing AC adapter and system firmware recognise it without changes.
