Compatible Dell replacement battery
This 40Wh 14.8V lithium-ion pack replaces the original M5Y1K unit across a wide range of Dell Inspiron, Latitude and Vostro notebooks. It fits 14, 15 and 17 inch models from the 3000, 5000 and 7000 series including the 3451, 3452, 3458, 3459, 3551, 3552, 3558, 3559, 3567, 5551, 5555, 5558, 5559, 5755, 5758 and 5759 families.
Fits without adapters or extra cables
The battery uses the same four-cell layout and connector as the factory part so it slots straight into the existing compartment. No BIOS update or mounting bracket is required and the original charger continues to work. Builders who need a higher-capacity pack or a different voltage will not be served by this unit.
Runs cool with built-in protection circuits
CE, RoHS and FCC certified cells include over-charge, over-discharge and short-circuit safeguards that keep temperatures stable during normal office workloads. The pack draws power only when the laptop requests it, adding no audible noise and no measurable heat beyond the system’s own thermal envelope.
