40Wh replacement battery for Dell Inspiron

This 40Wh lithium-ion pack replaces the original M5Y1K module in a wide range of Dell Inspiron 14, 15 and 17 models from the 3000 and 5000 series. It also fits select Vostro and Latitude units. The four-cell design restores factory runtime for everyday office and study workloads.

14.8V 2600mAh capacity and cell grade

Rated at 14.8 volts and 2600mAh, the battery delivers the same watt-hour figure as the stock unit. Grade A cells provide consistent charge acceptance and low self-discharge. Runtime will diminish under sustained heavy loads such as gaming or video rendering, where the 40Wh reserve depletes quickly.

M5Y1K part-number match decides fit

The single specification that confirms compatibility is the M5Y1K part number printed on the original battery or listed in the Dell service tag. If that code is absent, the pack will not align with the laptop's connector or firmware. Verify the part number before purchase.

Questions about this item

Will the 14.8 V M5Y1K battery fit alongside the original charger in my Inspiron 15-5558?

Yes, the 40 Wh pack matches the 14.8 V rating used by the 15-5558 and other listed Inspiron 14, 15 and 17 models, so the existing AC adapter will charge it normally.

How can I verify the 4-cell lithium-ion pack is healthy after installing it?

Check that the BIOS reports 14.8 V and roughly 2600 mAh capacity, then run a full charge-discharge cycle; the battery should reach 100 % and deliver several hours of runtime.

Does the box include only the M5Y1K battery or are screws and tools supplied as well?

Only the 40 Wh M5Y1K battery is included; any case screws or prying tools needed for the swap must be sourced separately.
