This Dell P49G battery features high quality LG Chem Lithium-ion cells. Quality components in a battery cost more but the benefit is a battery that last 3-5 years vs the 3-6 months of low end cheaper batteries.

This P49G battery is compatible with the Dell Inspiron 14 5442, 5447, 5448 and Inspiron 15 (5442) (5445) (5447) (5547) (5448) and Latitude 4350 & 3550.

This P49G battery is a 4 cell thin battery but it also comes in a 3 cell version. This is the higher capacity battery pack which is the same size as the 3 cell battery, but is a much better value as it runs 25% longer than the cell 39 Whr battery.
