Dell 7T8CD 53 Wh replacement battery

This 53 Wh lithium-ion pack is built to replace the original Dell 7T8CD cell in compatible laptops. It delivers 3530 mAh at 15 volts and ships in a black four-cell housing. The unit is new and matches part numbers 07T8CD, H5CKD, JK6Y6 and TXD03. Buyers who need a higher capacity or a different voltage should look elsewhere.

Simple swap with basic precautions

Installation typically requires removing the bottom cover, disconnecting the old pack and fitting the new one in the same orientation. Take care not to pinch the ribbon cable and ensure the connector seats fully before reassembly. A loose connection can prevent charging or cause the system to report an unrecognised battery. Static discharge can damage the cells, so ground yourself before handling.

Verify the exact part number first

Check the label on your existing battery for 7T8CD, H5CKD, JK6Y6 or TXD03 before ordering. Confirm the laptop model lists this part as compatible in the service manual. The replacement must match the original 15 volt rating and physical layout. Systems that require a different cell count or connector keying will not accept this pack.
