42Wh 11.4V Li-ion replacement battery

The 2-Power WDX0R is a three-cell lithium-ion battery rated at 42Wh and 11.4V, built as a direct replacement for the Dell WDX0R pack. It fits a wide range of Inspiron and Latitude laptops, including 13, 14, 15 and 17 inch models from the 3000, 5000 and 7000 series.

Suits owners of listed Dell models needing a 42Wh

This battery works only for systems that originally shipped with the 42Wh WDX0R or its listed part-number equivalents such as P69G and 3CRH3. It will not fit laptops that require the 56Wh 33YDH four-cell battery or the 42Wh YYRD6 variant, so buyers must verify the original battery label before ordering.

42Wh capacity for typical daily workloads

At 42Wh the pack delivers enough energy for several hours of office tasks, web browsing or media playback on compatible ultraportable and mainstream chassis. Runtime will fall short on larger 15 and 17 inch models under heavy load, and the battery cannot be used to upgrade a system designed for the higher-capacity 56Wh version.

Questions about this item

Will this 42Wh WDX0R battery fit my Dell Inspiron 15 5570 without any extra parts?

Yes, it is a direct replacement for the original 3-cell 11.4V pack used in the Inspiron 15 5570 and listed compatible models.

Can I keep my existing 100W 20V AC adapter when swapping to this 11.4V battery?

The adapter supplies 20V to the laptop's charging circuit, which then manages the 11.4V battery; they work together normally.

How do I confirm the new 3-cell 42Wh battery is recognised after installation?

Power on the laptop, open the BIOS or Windows battery report, and verify it shows 11.4V, 42Wh and three cells.
