NShi 7CJRC 11.4V battery for Latitude E7270 E7470

This new 3-cell lithium-ion replacement battery delivers 11.4V and 42Whr capacity for Dell Latitude E7270 and E7470 ultrabooks. It matches OEM part numbers 7CJRC, 21X15, 021X15 and 451-BBSW. The pack is built for primary internal use in these specific models.

Internal installation requires bottom-case removal

Installation involves removing the bottom cover, disconnecting the old pack and fitting the new unit into the same bay. The connector aligns only one way; forcing it risks pin damage. Static discharge can harm the protection circuit, so ground yourself before handling. No soldering or firmware steps are needed.

Verify exact model and OEM part number before

Confirm the laptop reads Latitude E7270 or E7470 on the service tag. Cross-check the original battery label for part numbers 7CJRC, 21X15, 021X15 or 451-BBSW. Other Latitude series use different voltages or form factors and will not accept this pack. This unit is not for external charging or non-Dell devices.

Questions about this item

How can I verify the 11.4V 42Whr battery is working correctly after installing it in my Dell Latitude E7270?

The system BIOS should report the correct 11.4V voltage and 42Whr design capacity, and Windows Battery Report will show a full charge near 3684mAh with stable discharge.

What comes in the box with the GreenTech 7CJRC replacement battery and what must I purchase separately?

The box contains the 3-cell Li-Ion battery unit only; no tools, screws, or installation guides are included, so have a small Phillips screwdriver ready.

Which OEM part number should I match — 7CJRC, 21X15, 021X15 or 451-BBSW — to ensure the right fit for my Latitude E7470?

All four numbers refer to the same 11.4V 42Whr 3-cell battery; matching any one of them on your original battery label confirms compatibility.
