PISKEKAT CR2032 CMOS laptop battery 3-pack 2-pin wires

SKU CH-DGSH-56CVP

CR2032 CMOS backup battery with two-pin wires fits Dell Latitude and Alienware models, three per pack

  • Battery typeLaptop Batteries
  • Compatible with many Dell Latitude and Alienware models
  • CR2032 cell delivers reliable 3V backup power for BIOS
  • Two-pin wire connector enables quick 10-minute installation
  • Heat-shrink insulation protects the cell for extended service life
  • Three-pack provides spare batteries for multiple laptops

Replacement CMOS battery for Dell laptops

This three-pack of CR2032 coin cells with two-pin wires replaces the real-time clock battery in Dell Latitude models including the 2110, 2120, E5440, E5470, E6230, D610, D620, D630, D810, D830 and Alienware M17x. It restores BIOS settings and system time when the original cell is exhausted. Builders who need a different connector pinout or voltage should look elsewhere.

Passive component with no thermal or acoustic impact

The battery is a passive 3 V lithium cell that generates no heat, draws no measurable current in normal operation and produces no noise. It sits inside the chassis and maintains the RTC circuit without affecting system thermals or power draw. No fan, radiator or active cooling is involved.

Long-term reliability under continuous duty

The CR2032 chemistry is designed for years of continuous low-drain service keeping the real-time clock alive while the laptop is off or unplugged. Heat-shrink insulation on the wires protects the connection from vibration and temperature cycling inside the case. Buyers who expect a rechargeable or high-capacity pack for main system power will not find it here.

Questions about this item

How do I install the CR2032 CMOS battery with 2-pin wires on a Dell Latitude E5470?

Disconnect the old 2-pin connector, route the new wires through the chassis clips, and seat the CR2032 cell in its holder; the supplier notes the swap takes about 10 minutes.

When will the CR2032 CMOS battery need replacement in a Dell Latitude 2120?

The CR2032 coin cell typically holds BIOS settings for several years; replace it when the system loses time or shows CMOS checksum errors on boot.

What is the first limitation during continuous use of this CMOS battery in a Dell Latitude D630?

The CR2032 chemistry limits sustained current to microamp levels, so the battery cannot power anything beyond the real-time clock and CMOS memory.
