The Dell 1W2Y2 is a 51 Wh lithium-ion battery built with four cells at 7.6 V. It matches part numbers 01W2Y2, 242WD, GG4FM, MC34Y and R97YT for a drop-in fit. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Runs cool with no moving parts

The solid-state chemistry produces no fan noise and adds negligible heat during normal charging or discharge cycles. Power draw follows the laptop's own management system without extra load on the AC adapter.

Slim 4-cell pack fits original bay

The four-cell layout keeps the profile thin so the battery seats flush in the factory compartment. Connectors align with the Dell socket for a secure click and reliable contact day after day.

Questions about this item

How do I install the Dell 1W2Y2 4-cell battery and what step is often missed?

Power off the laptop, unplug the AC adapter, remove the old pack, insert the new 7.6 V battery until the latches click, then reconnect the charger before turning on.

What maintenance or replacement will the 51 Wh lithium-ion pack need later?

Lithium-ion cells degrade with each charge cycle; expect reduced run-time after several hundred cycles and plan to replace the pack when it no longer holds a useful charge.

What limit appears first during sustained use of this 7.6 V battery?

The 51 Wh capacity sets the total run-time per charge; under continuous load the pack will reach its energy limit and require recharging before other thermal or voltage limits are hit.
