What this battery replaces

The NShi 7WMM7 is a 7.4V 28Wh lithium-ion pack built to replace Dell part numbers 7WMM7, CFC6C, CP305193L1, DL011301-PLP22G01 and D1R74. It fits the Dell Venue 11 Pro Keyboard Dock D1R74 series and ships new with CE certification.

Thermals, noise and power

As a passive battery it produces no noise and draws no power while installed. Normal use follows the dock’s own thermal design; the pack simply stores 28Wh at 7.4V for mobile operation.

Build fit and clearance

The pack includes one battery and an instruction sheet. Buyers must open the dock’s back cover and confirm the exact part number before ordering because wire lengths may differ slightly from the original. It is not for users who cannot verify the part number or who need a different voltage or capacity.

Questions about this item

How do I install the 7WMM7 battery in the Dell Venue 11 Pro Keyboard Dock D1R74, and what step is often missed?

Open the back cover, verify the original battery part number matches 7WMM7, CFC6C, CP305193L1, DL011301-PLP22G01 or D1R74, then connect the new battery; the missed step is skipping the part-number check, which risks a wire-length mismatch.

What maintenance will the 7.4V 28Wh Li-ion battery need later?

On first use, drain to 5 % then charge to 95 % and repeat for 3‑4 cycles; afterwards, avoid leaving the AC adapter connected for long periods while the battery is in use to reduce wear.

What limit appears first during sustained use of this 28Wh pack?

The 28 Wh capacity itself is the limiting factor — runtime ends when the stored energy is depleted, and the 7.4 V output drops as the cells discharge.
