Adafruit 2×CR2032 Coin Cell Battery Holder 6V On/Off Switch

SKU CH-A02E-CCPCT

Holds two 20mm CR2032 cells in series for 6V output with a 2mm JST PH connector and on/off switch

  • Product typePrototyping Products
  • Ideal for compact portable and wearable builds
  • Two CR2032 cells in series deliver 6 V nominal
  • 2 mm JST PH connector with integrated on/off switch
  • Snap-shut plastic case weighs 4.7 g empty
  • 53 × 23 × 6 mm footprint with 150 mm lead length

Portable power for wearables

This coin cell holder fits two 2032 batteries in series to supply 6V nominal for small portable or wearable projects. The plastic body snaps open and closed and weighs 4.7 grams empty or 10.5 grams with cells installed. A built-in on/off switch lets you cut power without removing batteries. The 150mm lead ends in a 2mm JST PH connector.

Capacity and headroom

Two 20mm cells provide roughly 220mAh at 6V, which suits low-draw devices such as LED indicators or microcontroller boards. The holder accepts only 20mm coin cells, so larger formats will not fit. The single JST PH connector means one load at a time unless you splice the wires. Current capability is limited by the coin cell chemistry, not the holder itself.

Switch and connector benefits

The on/off switch adds a convenient way to preserve cell life during development or storage. The 2mm JST PH plug mates with matching headers on many Adafruit boards, but the lead can be cut and re-terminated for other connectors. The snap closure holds cells securely, yet tape can reinforce it for high-vibration use. No batteries are included with the holder.

Questions about this item

Will this 53 mm holder fit alongside my existing 20 mm coin-cell boards?

The holder measures 53 mm long by 23 mm wide by 6 mm thick, so it sits flush with other 20 mm cell modules in a compact wearable stack.

How can I verify the 6 V output is present after wiring the JST PH connector?

Switch the on/off toggle to on, then measure across the JST PH pins — you should read roughly 6 V nominal from the two series CR2032 cells.

Does the package include CR2032 cells or must I buy them separately?

Batteries are not included; you need to purchase two CR2032 coin cells separately, while the holder, switch and 150 mm JST PH lead come pre-assembled.
