Dell CR2032 CMOS Battery for Alienware Alpha

This pack contains two 3 V CMOS BIOS batteries with attached cables and two‑pin connectors. They are designed for Dell Alienware Alpha ASM100 units and Dell Latitude D610 and D620 laptops. Buyers who need a replacement for a different Dell model or a non‑Dell system should verify the part number before ordering.

Installation notes for the CMOS coin cell

The battery plugs directly into the motherboard header via its pre‑wired two‑pin connector, so no soldering is required. Accessing the header on the Alienware Alpha or Latitude chassis typically involves removing the bottom cover or keyboard bezel. The main difficulty is reaching the connector in tight spaces; forcing the plug can bend the fragile pins.

Limits of the CR2032 form factor

A CR2032 coin cell supplies 3 V and maintains BIOS settings and the real‑time clock when main power is removed. Its capacity suits low‑current retention duties only; it cannot power any active component. The cell will eventually deplete and require replacement, typically after several years of continuous use.

Questions about this item

How can I verify the CMOS battery is working after installing it in my Alienware Alpha ASM100?

After installation, power on the system and enter the BIOS setup; the date and time should hold correctly after a full shutdown, confirming the 3V CR2032 cell is functioning.

What comes in the package and is any extra cable or connector needed for the Dell Latitude D610?

The lot includes two CR2032 coin cells, each with a 2-pin cable and jacketed connector attached; no separate cable or adapter is required for the listed Latitude models.

Which part number should I select for a Dell Latitude D620 repair?

Use part number H3GDV (also listed as 0H3GDV or CN-0H3GDV) — this 3V CMOS coin cell with cable matches the D620 and the Alienware Alpha ASM100.
