Dell Alienware 13 R1 Battery — Durable Replacement

The Dell Alienware 13 R1 Battery is a 51Wh internal replacement battery for compatible first-generation Alienware 13 systems. Dell battery documentation maps battery type 3V806 to Dell part number 2P9KD and confirms a 51Wh, 14.8V specification, while Dell support identifies the 3V806 as the 4-cell battery used with the Alienware 13 R1. For UAE buyers, these details make it easier to match the correct battery without confusing it with later Alienware 13 generations.

Which Battery Fits the Alienware 13 R1?

The Alienware 13 R1 uses the 3V806 / 2P9KD 51Wh battery family in this configuration. The battery is rated at 14.8V and uses a 4-cell lithium-polymer layout.

Key specifications to compare with your existing battery include:

• 51Wh energy capacity
• 14.8V battery voltage
• 4-cell configuration
• 3V806 battery type number
• 2P9KD Dell part number
• Internal lithium-polymer design

Why Part Number Matching Matters More Than Appearance

Alienware 13 batteries can look extremely similar even when their electrical specifications differ. The Dell Alienware 13 R1 Battery should therefore be selected by checking the part number, voltage and watt-hour rating printed on the battery already fitted inside the laptop.

Dell's own safety documentation specifically pairs 2P9KD with battery type 3V806, rated at 51Wh and 14.8V. Matching those identifiers is a more reliable approach than choosing a battery based only on the Alienware 13 name.

Restore Portable Use to an Older Alienware

Battery capacity naturally declines after years of charge and discharge cycles. A correctly matched replacement can make an Alienware 13 R1 practical away from the charger again for browsing, office work, streaming and other everyday tasks.

Gaming and GPU-heavy workloads will consume considerably more battery power, so actual runtime depends on workload, display brightness and system settings rather than battery capacity alone.

Avoid Mixing R1 with Later Alienware 13 Batteries

Later Alienware 13 systems can appear with different capacity and voltage combinations, including 62Wh / 15.2V batteries. Because the form factor can be similar, checking 3V806, 2P9KD, 51Wh and 14.8V before ordering helps prevent a cross-generation mismatch.
