Replacement battery for Dell 17-inch laptops

This 42 Wh lithium-ion pack is built for Dell Inspiron 17 models 5765, 5767, 5770 and 5775 as well as Vostro 5468, 5568 and 5471. It matches the original 11.4 V specification and uses a four-cell layout to restore factory-level runtime. Buyers who need a higher-capacity alternative or a different form factor should verify the original part before ordering.

Sustained discharge behaviour

The 42 Wh rating delivers consistent energy output across typical workloads such as document editing, video playback and web browsing. Lithium-ion chemistry maintains stable voltage through the middle of the discharge curve, avoiding the sudden drops seen in aged cells. Heavy continuous loads like rendering or gaming will deplete the pack faster than light office use.

Thermals, noise and power draw

The battery operates silently with no moving parts and adds negligible heat during normal charging and discharging. Power draw follows the laptop's own management profile, so thermal behaviour mirrors the original equipment. CE and RoHS certification confirms compliance with safety and environmental standards.

Questions about this item

Does the 11.4 V 42 Wh lithium-ion pack generate noticeable heat or drain quickly when the laptop runs all day?

The 42 Wh lithium-ion cell delivers steady voltage at 11.4 V, so typical workloads produce only normal warmth and the pack sustains a full day of mixed use without rapid depletion.

What must I already own for this WDX0R battery to work in my machine?

You need a Dell Inspiron 17 5765 5767 5770 5775 or Vostro 5468 5568 5471 that currently uses the 4-cell 42 Wh form factor shown in the product photos.

Will this replacement battery fit alongside the original chassis screws and battery bay of an older Inspiron 17 5765?

Yes, the pack is built to the exact 4-cell 42 Wh dimensions for the 5765, so the existing screws and bay accept it without modification.
