By coincidence, there are two small 1mm diameter holes in the metal connection tabs, just large enough for a #5 or smaller needle to pass through. One tab connects to common ground (negative) and the other tab is +3 Volts.\nThis holder is meant to be used with Lithium CR2032 (20mm diameter, 3.2mm thick) sized coin batteries. These are almost always 3V at about 200+ mAh capacity.\nInserting the coin is easy, the holder is very sturdy, and it snaps out with a push. Its got a nice flat plastic back that you can easily glue in place for extra mechanical stability. It mounts Directly on PCB. Good for space saving applications.\nThis space saving design allows components to be placed under the holder. This is ideal when board space is more important then board height.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eReliable spring tension assures low contact resistance\u003c\/li\u003e\n\u003cli\u003eRetains battery securely to withstand shock and vibration\u003c\/li\u003e\n\u003cli\u003eUnique notched slots assure quick and easy battery insertion and replacement\u003c\/li\u003e\n\u003cli\u003eBase material UL Rated 94V-0.\u003c\/li\u003e\n\u003cli\u003eImpervious to most industrial solvents\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -60°F to +293°F (-50°C to +145°C)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Microscale","offers":[{"title":"Default Title","offer_id":47681003127059,"sku":"CMP-2533","price":150.0,"currency_code":"NGN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/3191\/3491\/products\/bhold2032--500x500.jpg?v=1682021805"},{"product_id":"arduino-uno-usb-cable","title":"Arduino Uno R3 + USB cable","description":"\u003ch1\u003eArduino uno\u003c\/h1\u003e\n\u003cp\u003eArduino Uno is a microcontroller board based on the ATmega328P .
