Replacement Battery for Venue 11 Pro 7140

This Dr. Battery Professional Series unit is a direct replacement for the Dell Venue 11 Pro 7140 Series tablets. It uses Li-polymer chemistry rated at 7.4V and 4000 mAh. The pack matches original part numbers including 2H2G4, 451-BBKH, HFRC3, TXJ69 and 21CP5/63/105. It is sold new and ready to install.

Fits Inside the Tablet Chassis

The battery slides into the existing compartment without any extra cables or adapters. Its dimensions are 8.0x1.5x0.8 and it weighs 0.4, matching the factory form factor so the tablet closes normally. Integrated protection guards against over-charge, over-discharge, overheating and short-circuit, freeing you from external power bricks during mobile work.

Suits Owners of Matching Dell Tablets

Buyers with a Venue 11 Pro 7140 or Venue Pro 7140 whose original pack has lost capacity will regain full runtime. Users of other Dell models or different voltage requirements should look elsewhere, as this pack is built only for the 7.4V 7140 series.
