2-in-1 Accessory for Dell Latitude

This 2-in-1 accessory is a lithium-polymer replacement battery rated at 7.4 volts and 51 watt-hours. It is designed for Dell Latitude 14 E5450 series, Latitude 15.6 E5550 series and Latitude 12 E5250 notebook series. The part numbers G5M10, 8V5GX, R9XM9, WYJC2 and 1KY05 identify the correct fit.

Voltage and capacity limits

The 7.4-volt output and 51 watt-hour capacity match the original specifications for the supported Latitude models. The battery uses lithium-polymer chemistry which requires the laptop charging circuit to manage voltage limits correctly. It is not suitable for devices that require a different voltage or higher capacity.

Straightforward replacement

Installation involves removing the bottom case, disconnecting the old pack and connecting the new battery using the existing connector. The part numbers on the label must match G5M10, 8V5GX, R9XM9, WYJC2 or 1KY05 to avoid a mismatch. Common issues include forgetting to disconnect the internal cable before removal or seating the connector incompletely.
