Replacement Battery for Venue 11 Pro Tablets

This 28 Wh lithium-ion pack replaces the original 7WMM7 cell in Dell Venue 11 Pro D1R74 and CFC6C tablets and their keyboard docks. It restores mobile power for professionals who rely on the tablet form factor for field work or presentations.

Direct-Fit Design with Black Housing

The battery ships as a single black module that slots into the existing compartment without adapters or cables. Its 7.4 V output matches the factory specification, so the tablet recognises the pack immediately and charges through the standard dock or AC adapter.

Confirm that your device lists one of the following part numbers: 7WMM7, CFC6C, D1R74, RTY89, CP305193L1 or 21CP3/52/93-2. The pack is not compatible with other Venue models or non-Dell tablets, so cross-reference the label on your original battery first.
