Dell Alienware 13 R2 Battery — Lasting Replacement

The Dell Alienware 13 R2 Battery in this 51Wh configuration is a 4-cell internal battery designed for compatible Alienware 13 R2 laptops. Dell-hosted battery documentation maps 2P9KD to battery type 3V806 and confirms a 51Wh, 14.8V specification, while specialist Dell parts references identify 62N2T as a matching Dell part number for this configuration.

Which 51Wh Battery Fits the Alienware 13 R2?

For the 51Wh configuration, look for battery type 3V806 and compatible Dell part numbers such as 62N2T or 2P9KD. The confirmed specification is 14.8V with a 4-cell lithium-ion construction.

Important details to compare include:

• 51Wh battery energy
• 14.8V operating voltage
• 4-cell configuration
• Battery Type 3V806
• Dell P/N 62N2T / 2P9KD

Why Checking the Part Number Matters

The Alienware 13 R2 was available with more than one OEM battery capacity. Dell support identifies 51Wh 4-cell batteries under 62N2T and 2P9KD, while 62Wh 4-cell configurations used different part numbers such as 257V0 and 2VMGK.

That means “Alienware 13 R2” alone does not fully identify the battery. If your existing pack is marked 3V806, 62N2T or 2P9KD and carries a 51Wh / 14.8V rating, this is the specification to match.

Battery Losing Runtime? Restore Portable Use

Rechargeable batteries gradually lose usable capacity after repeated charging cycles. Replacing an ageing Dell Alienware 13 R2 Battery can restore more practical unplugged use for browsing, media, office applications and general everyday tasks.

Because the Alienware 13 R2 is a performance-oriented laptop, gaming and GPU-heavy applications naturally consume power faster than lighter workloads. Actual runtime will therefore depend on workload, display settings and overall system condition.

Don't Mix the 51Wh and 62Wh Versions

Replacement references show both 51Wh / 14.8V and 62Wh / 15.2V batteries for the Alienware 13 R2, with the same approximate physical dimensions appearing in replacement catalogues. Matching voltage, watt-hour rating and part number before purchase is therefore much safer than relying on shape alone.
