Replacement battery for Dell Latitude Vostro

This 40Wh lithium-ion unit replaces the original JK6Y6 pack in Dell Latitude 3410 3510, Vostro 5300 5301 5401 5402 5501 5502 and Inspiron 5300 5301 5401 5402 5408 5409 5501 5502 5508 5509 5400 5406 7405 7300 7306 7500 7506 2-in-1 Silver Series notebooks.

Who this suits and who should look elsewhere

Owners of the listed Dell models needing a direct 40Wh replacement will find the correct voltage and connector. Buyers whose laptop requires a higher-capacity pack or a different part number cannot use this unit. The battery does not fit Inspiron 7300 7306 7500 2-in-1 Black Series variants. Always verify the original battery model number before ordering.

Installation ease and common pitfalls

The pack fits into the standard battery bay and the included tools help remove the bottom cover. If the system does not recognise the new cell, reseat the connector and ensure it is fully engaged. Run the battery down to five percent then recharge; repeat three to four cycles to calibrate the fuel gauge. Do not discharge to zero during this process.
