Dell Alienware 13 Battery — Powerful Replacement

The Dell Alienware 13 Battery is a 51Wh replacement power pack for compatible Alienware 13 systems using the 3V806 battery family. Dell's own battery safety documentation directly maps Dell part number 2P9KD to battery type 3V806 and confirms a 51Wh capacity with 14.8V output. Matching these details before ordering is important because later Alienware 13 generations use different battery specifications.

Is 3V806 the Right Battery for Your Alienware 13?

The 3V806 / 2P9KD battery family is the verified 51Wh configuration associated with earlier Alienware 13 systems. Dell documentation confirms the 51Wh rating and 14.8V electrical specification, while replacement references list this battery for Alienware 13 and Alienware 13 R2 systems.

Check these details on your existing battery:

• Battery type number: 3V806
• Dell part number: 2P9KD
• Energy capacity: 51Wh
• Voltage: 14.8V
• 4-cell configuration

Battery Runtime Dropping? Restore Everyday Mobility

Rechargeable laptop batteries naturally lose usable capacity over time. Replacing a worn Dell Alienware 13 Battery can make the laptop more practical away from its AC adapter again for browsing, media, productivity and lighter everyday workloads.

Gaming and GPU-intensive applications will consume battery power significantly faster, so actual runtime depends on display brightness, workload and system settings.

Don't Mix This Battery with the Alienware 13 R3

Generation checking matters with this laptop family. Dell officially specifies the Alienware 13 R3 with a different 76Wh, 15.2V, 4-cell smart lithium-ion battery, so an R3 should not be treated as the same battery specification as this 51Wh 3V806 unit.

This distinction is especially useful because generic Alienware 13 replacement listings can sometimes group several generations together even when their batteries differ electrically.

Match the Label Before Ordering

Before purchasing, compare the battery inside your laptop with the 3V806 / 2P9KD, 51Wh and 14.8V specifications. The replacement form factor is commonly listed at approximately 299.2 × 92.04 × 13.35 mm.
