6-cell 58 Wh replacement battery

This new lithium-ion battery delivers 58 Wh and 5200 mAh across six cells for the Dell Studio 1535 1536 1537 1555 1557 and 1558 series. It matches part numbers WU946 WU965 WU960 KM958 MT264 MT276 KM965 KM887 PW773 KM904 KM907 312-0701 and the PP33L PP39L chassis codes.

Owners of listed Studio models needing a direct swap

Buyers whose original battery carries one of the listed part numbers can install this unit without modification. Laptops outside the Studio 1535 to 1558 range or with different part numbers will not be compatible so verify the sticker on your old pack before ordering.

Capacity and cell count decide fit

The 58 Wh 6-cell rating determines both physical thickness and runtime compared with 4-cell or 9-cell alternatives. If your service manual specifies a different watt-hour value or cell count this battery will not sit flush or meet the expected run time.

Questions about this item

How many charge cycles can the 58 Wh lithium-ion pack sustain before it needs replacing?

The pack is rated at 58 Wh and 5200 mAh; lithium-ion cells of this type generally deliver several hundred full cycles before capacity falls to a level that requires replacement.

What is the first limit reached when the battery runs continuously at full load?

The 58 Wh capacity is the limiting factor; sustained high draw will deplete the stored energy before any thermal or voltage threshold is hit.

Does the 6-cell 58 Wh unit generate noticeable heat or fan noise during all-day use?

The battery itself produces only modest warmth under normal discharge; any audible fan noise comes from the laptop's cooling system, not the pack.
