The Beisite WDX0R is a new 42Wh lithium-ion battery built to 11.4V for select Dell Inspiron 13, 15 and 17 models. It replaces part numbers WDX0R, 3CRH3, T2JX4 and 31CP5/57/81. Buyers with a compatible Inspiron can restore original runtime without adapter changes.

Upgrade from depleted or swollen packs

Swap this unit in when the original pack no longer holds charge or shows physical swelling. The jump is worth it when the laptop still meets daily workloads but battery life has dropped below usable levels. It is not for machines outside the listed Inspiron 13 5368 5378 7368 7569 7579, 14 7460, 15 5565 5567 5568 5578 7560, 17 5765 5767 series.

Limited to 11.4V 42Wh lithium-ion form factor

The pack fits only the mechanical and electrical interface defined for the models above. It cannot serve higher-capacity needs, different voltage rails or non-Inspiron chassis. Users requiring extended runtime beyond 42Wh or a different connector layout must look elsewhere.

Questions about this item

Will the WDX0R 42Wh battery fit inside my Inspiron 13 5378 without modification?

Yes, the WDX0R is built to the original chassis dimensions for the Inspiron 13 5378 and 5368 series, so it seats in the existing battery bay with no trimming or adapters needed.

What is the correct order to connect the WDX0R battery cable during installation?

Insert the battery into the bay first, then plug the connector into the motherboard header; reversing this order can bend the delicate pins on the 31CP5/57/81 connector.

Which part numbers confirm that a replacement WDX0R unit is the correct match for my Inspiron 15 5568?

Match the replacement against 3CRH3, T2JX4 or 31CP5/57/81 — any of those codes on the new pack confirms compatibility with the 5568 model.
