Replacement Battery for Dell Inspiron

This 40Wh lithium-ion battery replaces the original M5Y1K pack in Dell Inspiron 14, 15 and 17 models across the 3000 and 5000 series. It is aimed at owners whose factory battery no longer holds a useful charge and who want a direct drop-in replacement without changing the laptop.

Simple Swap with Built-In Safeguards

The pack fits the existing battery bay and connects to the stock connector, so installation only needs a screwdriver and a few minutes. Multi-protection circuitry guards against short circuit, over-voltage, over-current and deep discharge. Common issues arise when the part number on the old battery does not match the M5Y1K list, so verify the code before ordering.

40Wh Capacity for Typical Daily Use

Rated at 14.8V and 2600mAh, the four-cell design delivers up to 500 recharge cycles under normal conditions. It comfortably powers office work, web browsing and video playback for several hours. Heavy workloads such as sustained gaming or video rendering will drain the pack faster and may require a mains connection sooner.

Questions about this item

How can I confirm the 14.8V 40Wh M5Y1K battery is working correctly after installing it in my Dell Inspiron?

After installation the laptop should power on without the AC adapter, show a charge percentage in the OS, and run on battery alone; the built-in protections against short circuit, over-voltage, over-current and deep discharge will engage automatically if any fault occurs.

What comes in the box with the M5Y1K battery and do I need to buy anything else to fit it?

The package includes one 40Wh 14.8V 4-cell lithium-ion M5Y1K battery and a printed manual; no extra cables, tools or adapters are required for installation.

Which M5Y1K version should I choose for a Dell Inspiron 15 5000 series 5558?

The single 40Wh 14.8V 4-cell M5Y1K model listed replaces part numbers P51F, VN3N0, GXVJ3, HD4J0, 453-BBBR, 451-BBMG and others, and is specified for Inspiron 15 5000 series 5558 among many compatible models.
