Maxell ML2032 rechargeable 3V button coin cell CMOS battery

SKU CH-N1ZN-EZ5SR

Rechargeable 3 V coin cell that keeps CMOS settings alive on motherboards using the 2032 size

  • Rechargeable design reduces replacement frequency
  • 3 V output maintains CMOS settings reliably
  • 2032 form factor fits standard motherboard holders
  • Maxell brand ensures consistent manufacturing quality
  • Single cell package provides immediate installation

Purpose & Audience

The Maxell ML2032 is a rechargeable 3V button coin cell designed to maintain CMOS settings on a motherboard. It suits system builders and repair technicians who need a reliable replacement for the original battery soldered or clipped to the board.

Thermals Noise Power

As a primary lithium cell it generates no audible noise and negligible heat during normal operation. The rechargeable chemistry accepts a trickle charge from the motherboard circuitry, drawing only microamps when the system is powered off.

Build Integration

The cell fits the standard 2032 footprint used on most desktop and laptop boards, so no adapter or holder modification is required. It frees the builder from sourcing disposable CR2032 equivalents and supports repeated charge cycles over the board's service life.

Highlights

  • Rechargeable design reduces replacement frequency
  • 3 V output maintains CMOS settings reliably
  • 2032 form factor fits standard motherboard holders
  • Maxell brand ensures consistent manufacturing quality
  • Single cell package provides immediate installation

Questions about this item

How do I install the ML2032 cell and which orientation mistake should I avoid?

Slide the cell into the motherboard holder with the marked positive side facing up; reversing it prevents charging and leaves the CMOS unpowered.

When will the ML2032 need replacement and what signs appear first?

After several years the cell holds less charge, so the system clock drifts and BIOS settings reset after each power-off.

What sustained-load limit appears first on the ML2032 during continuous trickle charging?

The internal chemistry gradually loses capacity, so the voltage sags below the level needed to keep CMOS data intact.
