Genuine Dell CMOS battery for compatible laptops

This CR2032 coin cell delivers 3 volts and 220 milliampere-hours to maintain BIOS settings and the real-time clock when main power is removed. It is supplied new as a direct Dell OEM replacement part number C8KT2.

Voltage and capacity match the original

The cell provides exactly 3 V and 220 mAh, the electrical values required by the listed Dell Latitude, Precision, Alienware, Inspiron and XPS models. A different voltage or capacity would prevent the firmware from retaining configuration data.

The package contains only the battery itself, so installation is a direct swap without cables, drivers or configuration utilities. Buyers who need a complete service kit with tools or thermal pads will not find them here.

Questions about this item

How long will the 220 mAh CR2032 keep BIOS settings alive in a Dell laptop?

The 220 mAh cell is designed to maintain CMOS data for several years of normal use; actual life depends on how often the main battery is removed or fully drained.

What connection does the C8KT2 use to reach the motherboard?

It ships with a pre-attached two-pin connector that plugs directly into the CMOS header on supported Dell boards.

Will the C8KT2 fit inside a Latitude E7450 chassis?

Yes — the E7450 is listed among the compatible models, so the battery and its cable are sized for that compartment.
