Product Overview
Engineered for compact circuit boards, the PartsMine A-869 provides a through-hole mounting solution for standard 20mm coin cells, including CR2032 and CR2025 lithium button batteries. A molded plastic housing secures the cell in place while dual PCB solder pins deliver dependable board termination.
Key Features
- Accommodates standard 20mm diameter coin cells, including CR2032 and CR2025
- Two-pin through-hole solder terminals for rigid PCB mounting
- Dual-leaf center spring contact ensures steady negative terminal pressure
- Side retention clip grips positive perimeter rim to prevent cell dislocation
- Molded black plastic housing isolates terminals and stabilizes the battery
Applications
- Soldering into microcontroller development boards to maintain real-time clock (RTC) timekeeping during main power loss
- Replacing broken or corroded coin cell clips on vintage computer motherboards and handheld game cartridges
- Powering low-current hobbyist circuits, LED throwies, custom badge builds, and breadboard prototyping projects
- Backing up volatile SRAM in industrial automation controllers and data loggers
Frequently Asked Questions
Will this holder accept both CR2025 and CR2032 batteries?
Yes. Both batteries share a 20mm diameter. The spring retention clip accommodates the 2.5mm thickness of a CR2025 as well as the standard 3.2mm height of a CR2032 cell.
Which terminal connects to the battery's positive side?
The vertical side clip contacts the positive (+) rim and top face of the coin cell, while the center dual-leaf spring contacts the negative (-) bottom face. The price per piece steps down with quantity, and the price-break table on this page shows each step.
Every real-time clock and memory backup starts with a steady contact holding onto three volts. Solder it in, snap the battery into place, and your circuit keeps running when the main power cuts out.
