Compatible Dell Inspiron Models

Installation and Fit

The pack uses a 4-cell design rated at 11.4V and matches the original form factor for the listed models. Because two different batteries exist for some of these laptops, you must compare the physical shape and connector with your current unit before fitting.

Lithium-ion chemistry delivers stable voltage across the discharge cycle with minimal heat during normal office or media use. The cell layout keeps internal resistance low, so the pack runs cool and quiet while supplying the 42Wh capacity.
