11.4V 42Whr replacement for Latitude E7270 and E7470

This new GreenTech battery replaces the original Dell 7CJRC, 21X15, 021X15 and 451-BBSW packs. It uses a 3-cell lithium-ion design rated at 11.4 volts and 42 watt-hours. The unit is built for Dell Latitude E7270 and Latitude E7470 notebooks.

Fits the internal battery bay without extra parts

Installation uses the existing latch and connector inside the Latitude chassis. No additional cabling, adapters or mounting hardware are required. The 3-cell form factor keeps the original profile and weight distribution.

Restores runtime lost to an aged or failed pack

Swapping out a depleted original cell brings the laptop back to its factory capacity of 3684 milliampere-hours. The upgrade is worthwhile when the old battery no longer holds a useful charge or shows swelling. It does not add capacity beyond the original specification.
