This maker didn\u2019t just crack open the battery and start drilling. They built a makeshift fan out of a toy car motor, some blue electrical tape, and a propeller to safely drain the thing over three days. Three full days of waiting for a janky desk fan to suck the last electrons out of a battery so they could avoid turning their workspace into a lithium fire hazard. That\u2019s either extreme patience or mild insanity, and honestly, I respect both.<\/p>\n<p>Designer: Slivki Show<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-582875\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_1.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_1.jpeg\"><\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-582876\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_2.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_2.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-582876\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_2.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_2.jpeg\"><\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<div style=\"padding: 4px; margin: 18px auto 20px; text-align:center;\"><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-7222236028814181\" crossorigin=\"anonymous\" type=\"f42bc5a748003e29a46a4ef2-text\/javascript\"><\/script><br \/>\n<!-- In-Content-Ad-1 --><\/p>\n<p><script type=\"f42bc5a748003e29a46a4ef2-text\/javascript\">\n<\/script><\/div>\n<\/div>\n<p>The disassembly process alone is wild. They started with thin drill bits, worked up to thicker ones, then had to break out a rotary tool with high carbon steel bits because apparently battery casings are tougher than anyone expects. There\u2019s this moment where they wrap the whole thing in tape to catch metal fragments, put on a rubber glove like they\u2019re defusing a bomb, and start yanking out the battery core with pliers. Then they\u2019re scraping out the guts with a popsicle stick. A popsicle stick! The juxtaposition of power tools and wooden sticks is somehow perfect.

The sound holes could\u2019ve been a disaster. Their first attempt with a ruler looked terrible, so instead of accepting wonky holes, they 3D printed a custom drilling template with 60 perfectly aligned holes and reinforced guiding channels to lock the drill bit in place. One millimeter of drift would mean starting over, so they zip-tied and hot-glued this template down like their life depended on it. When it came off, those holes were lined up in perfect rows. That\u2019s the kind of problem-solving that separates people who tinker from people who actually engineer solutions. You physically cannot achieve that precision by hand.<\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-582878\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_4.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_4.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-582878\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_4.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_4.jpeg\"><\/p>\n<div class=\"code-block code-block-2\" style=\"margin: 8px 0; clear: both;\">\n<div style=\"padding: 4px; margin: 18px auto 20px; text-align:center;\"><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-7222236028814181\" crossorigin=\"anonymous\" type=\"f42bc5a748003e29a46a4ef2-text\/javascript\"><\/script><br \/>\n<!-- In-Content-Ads-2 --><\/p>\n<p><script type=\"f42bc5a748003e29a46a4ef2-text\/javascript\">\n<\/script><\/div>\n<\/div>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-582879\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_5.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_5.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-582879\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_5.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_5.jpeg\"><\/p>\n<p>The electronics work is where most hobbyist projects die, but this one survived. Six dollar Bluetooth circuit board, tiny speaker, mini battery, push button, LEDs for power and charging indicators. Sounds simple until you\u2019re trying to desolder 1mm LEDs with a soldering iron tip so massive you can barely see what you\u2019re doing. They literally describe it as \u201cnearly impossible to make out what was happening\u201d with their naked eyes. Yet somehow those microscopic components got wired up without burning anything out. The layout planning involved printing a Photoshop design onto masking tape to create a sticky template for drilling button and port holes. That\u2019s the kind of creative workflow hack you develop after years of building stuff and learning what actually works.<\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-582880\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_6.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_6.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-582880\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_6.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_6.jpeg\"><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-582881\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_7.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_7.jpeg\"><img loading=\"lazy\" decoding=\"async\" class=\"lazyload alignnone size-full wp-image-582881\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_7.jpeg\" alt=\"\" width=\"1280\" height=\"960\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2025\/10\/05\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/\" data-jpibfi-post-title=\"Someone Hollowed Out a Duracell Battery and Fit a Surprisingly Good Bluetooth Speaker Inside\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2025\/10\/someone-hollowed-out-a-duracell-battery-and-fit-a-surprisingly-good-bluetooth-speaker-inside\/duracell_speaker_7.jpeg\"><\/p>\n<p>Final assembly required UV-curing glue (the dental filling type), a 3D-printed speaker sleeve, and strategic decisions about not permanently bonding everything so future repairs stay possible. The bottom cover snaps on like the original battery cap. Two weeks of work produced a Bluetooth speaker that fits in your palm and actually sounds good. The metal casing could\u2019ve made it sound terrible, but the acoustics somehow worked out. Would I do this myself? Probably not. Do I respect the hell out of someone who spent 72 hours draining a battery with a homemade fan just to start this journey?
