It fits the Smart Scale 56323, 56350, 56320, and Smart Scale 23, among other models in the range. The battery powers the scale's electronics, including weight measurement circuits and data transmission.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSmart Scale series compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V battery bay, connector pinout, and BMS handshake protocol — one cell fits the full range without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the Smart Scale platform, confirmed the BMS accepted the cell without fault codes, and verified charge termination triggered correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test tip:\u003c\/strong\u003e\n    After installing this battery, let the scale complete its full power-on self-test without interruption. The BMS runs a verification check at startup — cutting power during that sequence can latch a false battery fault that persists until a complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm persisting after a confirmed full charge on a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Smart Scale's BMS stores a charge threshold calibrated to the original OEM cell chemistry. A new Ni-MH cell does not match that stored profile until it completes one full charge-discharge cycle. The alarm triggers because the BMS reads internal resistance above its acceptance threshold — not because the cell is actually low. Run one complete charge-to-discharge cycle and the profile resets to match the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScale will not power on after the battery has been sitting in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below the BMS's minimum recovery voltage — typically around 6.0V for a 7.2V pack — and the BMS locks out power-on to protect the circuit. Connect the scale to mains power first and allow a slow trickle charge for 30–60 minutes before attempting to power on. Once voltage recovers above the BMS threshold, normal startup resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381413576794,"sku":"BWCS-NTA563MD-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381413609562,"sku":"BWCS-NTA563MD-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381413642330,"sku":"BWCS-NTA563MD-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NTA563MD-1.webp?v=1778900625","url":"https:\/\/batteryweb.com\/products\/natus-smart-scale-56323-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
