Replacement battery for Dell Inspiron 15 series

The LXHY 357F9 is a 74Wh 11.1V lithium-ion pack built to replace the original battery in Dell Inspiron 15 7000, 7559, 7567, 7566, 7759, 7557 and 5577 models. It also covers the INS15PD series including 1548B, 1548R, 1748B and related part numbers. The six-cell design uses A-grade cells and carries UL, CE, FCC and RoHS certification. Two screwdrivers are included for the swap.

Fits without adapter changes

The pack matches the voltage and connector layout of Dell part numbers 0GFJ6, 71JF4, P57F, P65F and their variants, so it seats directly in the existing bay. No cabling or BIOS updates are required beyond the normal battery calibration cycle. Builders should verify the original battery model and physical shape before ordering, as the 42Wh WDX0R unit is not compatible.

Steady output through a full workday

The 74Wh capacity is rated for sustained discharge at the laptop's native load profile rather than a short burst benchmark. Under continuous mixed use the six cells maintain voltage stability until the firmware initiates the low-power state. The lithium-ion chemistry supports repeated full cycles with minimal capacity fade when stored at moderate temperature.

Questions about this item

How long will the 74 Wh capacity last under sustained load before the battery hits its voltage floor?

The 74 Wh rating at 11.1 V delivers roughly 6.6 Ah, so continuous draw at 1 C will deplete the pack in about one hour; lower loads extend run-time proportionally.

Does the 6-cell Li-ion pack run hot or make noise when the laptop is used all day?

The battery has no moving parts and generates only modest heat during normal charge or discharge; it adds no audible noise to the system.

Which original Dell part numbers must already be in the laptop for this 357F9 replacement to fit?

It replaces Dell part numbers 0GFJ6, 71JF4, 0357F9, P57F003, P65F001, P57F and P65F — confirm one of those is on your current battery before ordering.
