No Sew WDX0R 42 Wh 11.4 V laptop battery

Replacement battery for select Dell laptops

This 42 Wh lithium-ion unit operates at 11.4 volts and uses three cells to power compatible Inspiron 13, 14, 15 and 17 models as well as certain Latitude and Vostro systems. It replaces original part numbers such as WDX0R, 3CRH3, P69G and CYMGM. The battery is new and factory-tested to CE, FCC, ROHS and UL standards with built-in circuit protection.

Snap-in design with Grade A cells

The pack fits the original battery bay without tools or adapters, so installation follows the same steps as the factory unit. Grade A cells support rapid charging and energy-efficient discharge, while the integrated protection circuit guards against over-charge, over-discharge and short-circuit conditions during daily use.

Capacity fixed at 42 Wh

Runtime scales with the host system's power draw, so heavier workloads on 15-inch or 17-inch models will deplete the pack faster than light use on 13-inch or 14-inch units. The 11.4 V output is matched to the listed Dell platforms only; it will not fit or function in laptops that require a different voltage or form factor.
