Drop-in replacement for Latitude E7270 and E7470

This Thinkstar battery replaces Dell OEM part numbers J60J5, 451-BBSY, 451-BBSX, 451-BBSU, WYWJ2, R1V85 and 5F08V. It is built for the Latitude E7270 and E7470 ultraportables. The four-cell lithium-ion pack delivers 7.6 V and 55 Whr. Owners of other Latitude models or non-Dell laptops cannot use this unit.

Fits the existing battery bay without extra hardware

The pack slides into the standard compartment on the E7270 or E7470. No adapters, cables or firmware updates are required. It restores mobile operation for users whose original cell has lost capacity. Systems that need a higher-wattage pack or a different voltage will not accept this battery.

55 Whr capacity supports typical business workloads

At 7237 mAh the cell runs office applications, web browsing and video playback for a full workday under normal settings. Heavy CPU loads, discrete graphics or maximum screen brightness will drain it faster. Users who need extended runtime beyond 55 Whr must look for a larger-capacity alternative.

Questions about this item

How long will the 55 Whr capacity last before the 4-cell lithium-ion pack needs recharging under continuous load?

The 7237 mAh rating at 7.6 V delivers 55 Whr, so runtime depends on the laptop's power draw; heavier workloads deplete the pack faster.

Does the battery run hot or draw extra power when the Latitude E7270 or E7470 is used all day?

Normal operation stays within the 7.6 V design limits; the pack generates typical lithium-ion warmth but no excess heat or power draw beyond the system's standard charging circuit.

Which Dell Latitude models must I already own for this J60J5 pack to fit and work?

It replaces OEM numbers J60J5, 451-BBSY, 451-BBSU, 451-BBSX, WYWJ2, R1V85 and 5F08V in Latitude E7270 and E7470 systems.
