Compatible Dell Alienware 15 R3 Models

This replacement battery fits Dell Alienware 15 R3 systems including A15-7055, A15-9580, A15-9597 and AR3-1764. It is a new lithium-ion pack built to match the original form factor and connector layout. Buyers should compare the unit with product photos before installation to confirm physical alignment. It restores mobile power for users whose original cells no longer hold a useful charge.

99 Wh Capacity and 11.4 Volt Output

The pack delivers 99 Wh at 11.4 V using six premium lithium-ion cells. Runtime scales with the laptop’s actual power draw, so heavy workloads will deplete it faster than light use. Capacity diminishes over repeated cycles, a normal characteristic of the chemistry. The battery carries CE and RoHS certification for safety and environmental compliance.

Replaces Worn Original Batteries

This unit replaces a depleted factory battery when runtime has dropped below practical levels. The upgrade is worthwhile when the original pack no longer sustains a work session or requires constant tethering to mains power. It is not suited for users who need a second hot-swap pack or a higher-capacity alternative beyond 99 Wh. The one-year replacement warranty covers defects in materials and workmanship.

Questions about this item

Which Alienware 15 R3 sub-model matches my unit among A15-7055, A15-9580, A15-9597 and AR3-1764?

Check the service-tag sticker on the bottom of your laptop; the battery is validated for those four exact sub-models only.

What does the 99 Wh rating mean for daily runtime on my Alienware 15 R3?

A 99 Wh pack typically delivers several hours of mixed workloads — web browsing, video playback and light productivity — before needing a recharge.

Does the 11.4 V specification limit charging speed or compatibility with my original charger?

The 11.4 V rating matches the factory design, so the original Dell charger will charge the battery at its normal rate without any voltage mismatch.
