Before ordering, confirm that your existing battery carries one of the Dell part numbers M5Y1K, 453-BBBR, HD4J0, W6D4J or 451-BBUD. Check that the laptop model number printed on the base matches one of the four Inspiron series listed. Ensure the voltage printed on the old pack reads 14.8V and that the physical shape aligns with the four-cell form factor.

This unit replaces the Dell original M5Y1K battery and its associated part numbers 453-BBBR, HD4J0, W6D4J and 451-BBUD.

Questions about this item

Does the M5Y1K battery ship with any tools or cables, or is it just the 4-cell pack?

The box contains only the 14.8 V 40 Whr lithium-ion battery; no screwdrivers, cables or adapters are included.

What runtime can I expect from the 2600 mAh capacity in an Inspiron 5558 under normal use?
