The Dell Latitude E7440/E7450 Battery is a precision-fit, 52Wh Li-Polymer replacement for Dell's slim 14-inch Ultrabook-class business laptop — machines that IT managers and executives across Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, and Peshawar still use as reliable day-to-day workhorses in 2026. At Rs. 7,399, this is a competitive Dell Latitude E7440/E7450 battery price in Pakistan for a new, bench-tested unit. Available from N.N Laptops at Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore.
Specifications & Compatibility
This is a 3-cell Li-Polymer battery rated at 11.4V and 4,550mAh / 52Wh. The E7440 was officially marketed as an Intel Ultrabook, and Dell used Li-Polymer cells in the internal battery specifically to meet the Ultrabook chassis thickness requirement. Confirmed compatible with the Dell Latitude E7440, E7450, and the E7440 Ultrabook variant. Part number cross-references include Dell PN FNY7C / 9C26T / HJ8KP / 451-BBFW families. The internal battery is accessed from the base panel after removing Torx T5 screws; a plastic pry tool helps release the panel clips without damage.
Ultrabook-Grade Cells, Bench-Tested at N.N Laptops
The E7440/E7450 is now a well-aged platform, which means two things: original batteries are heavily cycled, and replacement part quality on the open market varies widely. At N.N Laptops, every Dell Latitude E7440/E7450 Battery is bench-tested on a load analyser to confirm it reaches its rated 52Wh capacity, that the protection circuit functions under simulated over-discharge, and that the BMS communicates correctly with Windows so the battery percentage reads accurately. We reject any unit that shows cell imbalance or below-spec discharge voltage — you receive only grade-A stock.
