Product Overview
Vertical coin cell battery holder designed for 20mm diameter cells including CR2032, CR2025, and BR2032. Features a 3-pin through-hole PCB configuration with two positive outer pins and a single center negative contact for stable board retention and correct electrical orientation.
Key Features
- Accepts standard 20mm diameter lithium coin cells (CR2032, CR2025, BR2032)
- Vertical orientation reduces board footprint compared to horizontal holders
- 3-pin through-hole layout with 5.0 mm pin pitch (10.0 mm outer-to-outer span)
- Black PA66 glass-filled thermoplastic body with molded positive (+) polarity marking
- Tin-over-nickel plated spring contacts for reliable cell retention
Applications
- Replacing damaged battery retainers on desktop motherboards, synthesizer cards, or industrial controller boards.
- Prototyping microcontroller projects and real-time clock (RTC) backup circuits on perfboard.
- Adding compact 3V battery backup to custom DIY synth builds and hobby electronics where vertical board clearance is available.
Frequently Asked Questions
Which coin cell sizes fit into this holder?
It accommodates 20mm diameter lithium coin cells, most commonly CR2032 and CR2025, as well as BR2032.
What is the pin spacing on the PCB terminals?
The three through-hole pins have a 5.0 mm pitch between adjacent pins, giving a 10.0 mm span from outer positive pin to outer positive pin.
How are the terminals configured for polarity?
The two outer pins connect to the positive battery casing, while the single center pin connects to the negative bottom terminal. The price-break table on this page gives the price per piece at each quantity.
Vertical mounting keeps your board layout compact, making room where standard flat battery clips crowd out adjacent traces. A clean, reliable swap for dead real-time clock clips and custom maker builds alike.
