6-cell 49Wh replacement battery for Dell Inspiron

This 6-cell lithium-ion pack is rated at 49Wh, 4400mAh and 11.1V. It matches the original MR90Y and XCMRD part numbers and fits a wide range of Inspiron 14, 15 and 17 models as well as Latitude 3440 and 3540 systems. The battery is sold new and ready to install.

Sustained discharge at rated capacity

The pack is tested to meet OEM specifications and delivers its full 49Wh rating over a normal work session rather than only in a brief burst. Six lithium-ion cells provide stable voltage through the discharge curve so the laptop can maintain performance until the low-battery threshold is reached.

Low heat output with built-in protection circuits

Integrated safety circuitry guards against short circuit, overheat and overload conditions during normal use. The cell chemistry and protection design keep temperature rise modest and fan noise unchanged compared with the original battery. No additional power draw is imposed on the laptop's charging system.
