40Wh 14.8V replacement battery

This 40Wh lithium-ion battery operates at 14.8V and is designed for select Dell Inspiron and Vostro laptops. It arrives new in black and replaces part numbers including M5Y1K, K185W, GXVJ3 and HD4J0. The pack is a direct swap for the original power source in compatible machines.

For owners of listed Inspiron and Vostro models

The cell fits the Inspiron 14 3000 and 5000 series, Inspiron 15 3000 series and several 17-inch configurations alongside matching Vostro 14 and 15 units. Buyers whose laptop requires a different voltage, capacity or physical layout should look elsewhere, as this unit only matches the specifications shown.

40Wh capacity at 14.8V

The 40 watt-hour rating at 14.8 volts determines whether this pack will power your device correctly. Verify that your original battery carries the same voltage and capacity before ordering, since a mismatch will prevent proper operation.

Questions about this item

Does the 14.8 V 40 Wh lithium-ion pack run hot during all-day use?

The 40 Wh cell operates at standard laptop voltage and typical discharge rates; normal warmth is expected but excessive heat suggests a worn cell or blocked vents.

Which original part number must match for this M5Y1K battery to fit my machine?

Match your old battery to M5Y1K, K185W, GXVJ3, HD4J0, WKRJ2, VN3N0 or 451-BBMG before ordering.

Will this replacement work in an older Inspiron 15-3551 that still has its factory charger?

Yes, the pack is listed for Inspiron 15-3551 and other 3000-series models, so the original 14.8 V charger remains compatible.
