Dell ALW17ED Battery Replacement

This 92Wh lithium-ion battery replaces the Dell ALW17ED-3828, ALW17ED-4718 and ALW17ED-4738 packs. It is built for owners of compatible Dell notebooks who need a new power source after the original cell has aged. The eight-cell design fits the specific chassis variants listed by the supplier.

Thermal and Power Behaviour

Lithium-ion chemistry delivers steady output at 14.8V during typical office or media workloads. The pack runs at normal laptop temperatures without active cooling and adds no audible noise to the system. Power draw follows the host device's own management profile.

Capacity Decides Fit

The 92Wh rating determines whether this unit matches your runtime requirements. Dell ships two different batteries for the same laptop family and they are not interchangeable; verify the original part number against the three model codes above before ordering. Buyers who need a different watt-hour value cannot use this pack.

Questions about this item

How do I install the 8-cell 92Wh battery in my Dell ALW17ED-3828 and which step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery connector before lifting it out, then connect the new 14.8V pack and secure it; the step most people skip is unplugging the connector first.

What maintenance or replacement will the 92Wh lithium-ion pack need over time?

The 8-cell lithium-ion battery will gradually lose capacity; plan to replace it when runtime drops below your needs, typically after a few years of daily charging.

What limit appears first when the 14.8V 92Wh battery runs under sustained heavy load?

Under continuous high drain the cells heat up and the built-in protection circuit will throttle output to keep temperatures safe, reducing available runtime.
