Compatible Vostro Models

This 42 Wh lithium-ion battery fits Dell Vostro 3491 5481 5581 5490 5590 and part number P93G001. It is a new four-cell pack rated at 11.4 V and carries CE and RoHS certification. The pack is designed as a direct replacement for the original battery in those specific models.

Replaces Worn Original Pack

It replaces a depleted or ageing factory battery that no longer holds a useful charge. The upgrade is worth it when runtime has dropped noticeably or the laptop shuts down unexpectedly under load. Two different batteries exist for these chassis so the original must be matched to the product photos before purchase.

Capacity and Runtime Headroom

The 42 Wh rating delivers several hours of typical office work, web browsing or video playback on a full charge. Runtime shortens with sustained high CPU or GPU load, maximum screen brightness or attached peripherals. The one-year replacement warranty covers defects in materials and workmanship.

Questions about this item

Will the 11.4V 42Wh 4-cell battery fit my Dell Vostro 5490 without modification?

This battery is built for the listed Vostro models including the 5490; the supplier notes two different batteries exist for these laptops, so match the shape and connector to your original before fitting.

What is the main installation step that causes problems when swapping the YRDD6 pack?

Many owners forget to disconnect the internal battery cable before removing the old pack; always unplug the connector first, then swap the 4-cell unit and reconnect firmly.

How often should the 42Wh lithium-ion pack be calibrated to keep the fuel gauge accurate?

Run a full charge and discharge cycle every two to three months so the firmware relearns the true capacity of the 4-cell pack.
