Dell 55Wh 4-Cell Replacement Battery

This 55Wh lithium-ion battery replaces Dell part numbers OPDNM2, 451BBSY, P61G, 1W2Y2, NJJ2H and 579TY. It is built for owners of compatible Dell notebooks who need a new power source after the original pack has degraded. The 4-cell design fits the factory bay without modification.

Steady 7.6V Output Under Load

The pack delivers a nominal 7.6V across the full discharge curve, so voltage sag stays minimal during long work sessions or media playback. Premium cells keep internal resistance low, reducing heat build-up when the laptop draws sustained current. Capacity remains consistent cycle after cycle.

Direct Fit With Visual Verification

Installation is a simple case swap: remove the old pack, align the connector, and secure the new unit. Two distinct battery variants exist for some Dell models, so comparing the replacement against photos of the original avoids ordering the wrong version. CE and RoHS markings confirm compliance.
