55 Wh replacement battery

The Damaite 4-cell lithium-ion pack supplies 7.4 V and 55 Wh of capacity for Dell Latitude E7270 and E7470 series notebooks. It is intended for owners whose original battery no longer holds a useful charge. Buyers needing a higher-capacity pack or a different voltage will not be served by this unit.

Part-number match J60J5 MC34Y R1V85

Compatibility is confirmed against part numbers J60J5, MC34Y, R1V85, 451-BBSX, 451-BBSY, 451-BBSU, 242WD and PDNM2. The cell fits Latitude 12 E7270 P26S001 and Latitude 14 E7470 P61G001 chassis. Installers who cannot verify one of these codes should not proceed.

Sustained discharge at 7.4 V

The four lithium-ion cells maintain the rated voltage through a full discharge cycle, delivering steady runtime for typical office workloads. Capacity remains consistent across repeated charges without the sharp drop-off seen in aged packs. Systems that draw peak loads well above the design envelope may experience shorter runtimes.

Questions about this item

How long will the 55 Wh rating actually run my Latitude E7270 or E7470?

A 55 Wh pack typically delivers several hours of mixed office work on the E7270 or E7470; exact runtime varies with screen brightness, CPU load and battery age.

Does the 7.4 V output match the original Dell J60J5 or MC34Y specification?

Yes, the 7.4 V rating matches the factory voltage for the J60J5, MC34Y and related Dell part numbers listed for these models.

Will the 4-cell black casing fit the internal bay of both the 12-inch E7270 and 14-inch E7470?

The battery is built to the same 4-cell form factor used in the E7270 P26S001 and E7470 P61G001 chassis, so it seats correctly in either bay.
