Replacement battery for Dell Inspiron and Latitude

This 11.1V 48Wh lithium-ion pack replaces Dell part numbers such as 8858X and 911MD. It fits Inspiron 14R 5420, 15R 5520 and 7720 models plus Latitude E5420, E5430, E6420 and E6430 series notebooks. The cell is supplied new from the manufacturer.

Lithium-ion chemistry limits and cycle life

Li-ion cells deliver their rated 48Wh when charged to 11.1V and discharged within the laptop’s designed voltage window. The supplier rates the pack for up to 500 full recharge cycles before capacity drops below useful levels. Deep discharges, constant high-temperature operation or long-term storage at full charge will reduce that cycle count.

Check your current battery part number before

Verify that the original battery label lists one of the compatible part numbers such as 04NW9, 2P2MJ, 312-1163 or 8858X. Confirm the laptop model matches the supported Inspiron or Latitude series shown above. Ensure the machine’s charging circuit and BIOS accept a 11.1V 48Wh pack.

Questions about this item

Which Dell models does the 8858X 48Wh battery fit?

This 11.1V 48Wh lithium-ion pack replaces the 8858X and 911MD part numbers. It is compatible with Dell Inspiron 14R 5420, 15R 5520, 5720, 7520, 7720 and Latitude E5420, E5430, E5530, E6420, E6430, E6520, E6530 series notebooks.

What does 48Wh mean for daily runtime?

The 48 watt-hour rating shows the total energy the pack stores. In a typical 14‑inch Dell running office tasks you can expect several hours of use per full charge; heavier loads such as video playback or gaming will reduce that time.

What connector standard does the 8858X battery use?

The battery uses Dell's proprietary multi-pin connector for the 14R and 15R chassis families. It fits the same socket as the original 8858X and 911MD packs, so no adapter or cable change is required.
