CMOS battery for Latitude E4200 and E4300

This 3.0 V lithium cell replaces the original CMOS backup battery in Dell Latitude E4200 and E4300 laptops. It supplies the low current needed to keep the real-time clock and BIOS settings alive when the main battery is removed or exhausted. The part matches OEM reference GC02000KG00.

Green lithium cell with wired connector

The battery measures 27.00 x 20.30 x 3.73 mm and comes in a green sleeve with a lead that plugs directly onto the motherboard header. No soldering is required and the non-rechargeable lithium chemistry delivers a stable 0.2 Ah capacity. The unit is brand new and 100 % OEM compatible.

Replaces a dead or leaking original CMOS battery

When the system clock drifts, BIOS settings reset or a CMOS checksum error appears at boot, this cell restores reliable operation. The upgrade is worth it whenever the original backup battery has lost its charge or shows signs of leakage on the board.
