This 40Wh lithium-ion battery operates at 14.8V and contains four cells. It replaces Dell part numbers including M5Y1K, VN3N0, 453-BBBR, 453-BBBQ, P51F and P47F. The pack is supplied new and rated for around 300 to 500 charge cycles.

40Wh capacity decides runtime

The 40 watt-hour rating determines how long the system runs on battery power. If your original battery shows a higher or lower watt-hour value, this unit will not match the expected runtime.

Questions about this item

Does this 14.8V 40Wh M5Y1K battery need any extra cable or bracket to fit my Dell Inspiron 5558?

No extra parts are required. The battery matches the original Dell part numbers such as VN3N0 and 453-BBBR, so it slots straight into the existing bay on compatible Inspiron, Latitude and Vostro models.

Will the 4-cell 14.8V pack charge correctly with the 65 W AC adapter I already use on my Latitude 3560?

Yes. The replacement operates at the same 14.8 V and 40 Wh rating as the factory unit, so the original Dell charger will charge it normally without any BIOS update.

How can I confirm the new M5Y1K is working properly after I install it?

Power on the laptop without the AC adapter; the OS should show the battery at 14.8 V and report a design capacity near 40 Wh. Run a full discharge cycle — the pack is rated for 300 to 500 cycles — and verify it holds charge for a typical session.
