Direct replacement for Dell Inspiron and Latitude

This 40Wh lithium-ion pack replaces the original M5Y1K battery in a wide range of Dell Inspiron 14, 15 and 17 models plus selected Latitude and Vostro units. It delivers 14.8V from four cells and matches the factory form factor for a straight swap. Buyers needing a higher capacity or a different voltage will not be served by this unit.

Simple bay swap with no soldering required

The battery slides into the standard compartment and locks with the existing latch, so no tools or soldering are needed. Alignment tabs prevent reverse insertion. The only common issue is a loose fit if the laptop's retention clips have worn down over time, which can cause intermittent contact.

Limited to 40Wh and 14.8V output

The pack supplies a fixed 40 watt-hours at 14.8 volts, so runtime is bounded by that capacity and the laptop's power draw. It cannot charge faster than the host's built-in controller allows, and it will not work with systems that require a different cell count or voltage.

Questions about this item

How do I confirm the M5Y1K 40 Wh battery is working after installing it in my Inspiron 5558?

The laptop should power on without the AC adapter, show the 14.8 V 40 Wh capacity in the OS battery report, and hold charge through normal use.

What comes in the box with the M5Y1K battery and do I need any extra parts for my Latitude 3460?

The package contains the 4-cell Li-ion battery only; no tools, cables or adapters are included and none are required for the listed Dell models.

Which capacity version of the M5Y1K should I choose for a Dell Inspiron 15 5000 5555?

This model is offered only as a 40 Wh 14.8 V 4-cell pack, so there is no alternative capacity to select.
