Who This Suits and Who It Does Not

Owners of the listed Dell models who need a factory-fit battery to restore original run time will find this a compatible match. Buyers whose laptops use a different part number, a different voltage or a higher capacity pack should look elsewhere because this unit only fits the models explicitly named above.

Checks Before Ordering

Confirm that the part number printed on your existing battery matches one of the codes in the compatibility list. Verify that your laptop charges at 11.1V and that the physical bay accepts a three-cell pack. Ensure the device is powered off and disconnected from mains before attempting the swap.

Questions about this item

Does this 43Wh battery require any additional hardware to install in a Dell laptop?

No, the 3-cell lithium-ion pack is a direct replacement that fits the existing battery bay without extra parts.

Will the 11.1V output work reliably with the original charging circuit in an older Dell notebook?

Yes, the voltage matches the factory specification so the legacy charging system will recognise and charge the pack normally.

How can I confirm the battery is delivering its rated 43Wh capacity after the first few charge cycles?

Run a full charge, then use the built-in Dell battery diagnostic or Windows power report to verify the design capacity reads 43Wh.
