Questions about this item
Does the battery arrive ready to install in my Dell Inspiron 15 3521, or do I need any tools or cables?
The battery is a direct replacement for the original pack in models such as the Inspiron 15 3521. No extra cables or tools are included; you only need a small screwdriver to open the battery bay.
I see several Dell model series listed — how do I know this MPL05271P-T01 fits my specific laptop?
Match your laptop model number or original battery part number (for example 0MF69, G019Y, MR90Y or XCMRD) against the compatibility list that covers Inspiron 14, 15 and 17 series plus Latitude 3440 and 3540.
The label says 4400 mAh and 49 Wh — what does that mean for daily run-time on an Inspiron 17 5748?
The 49 Wh rating reflects the total energy stored by the six lithium-ion cells at 11.1 V. Actual run-time depends on screen brightness, workload and power settings, but the capacity matches the original specification for the listed models.
