It fits the 800 Series medical weighing platform used in clinical and hospital settings. The battery powers the display and operational electronics that support patient weight measurement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAMERICAN SCALE 800 platform fit:\u003c\/strong\u003e\n    The 800 Scale uses a 12V sealed lead-acid cell with a specific footprint — 178.00 x 66.60 x 35.00mm. This replacement matches that form factor and voltage rail, so the BMS can handshake correctly on first power-up without throwing a voltage mismatch fault.\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 under the 800 Scale's load profile. The BMS accepted the cell without a chemistry rejection fault, and the charge circuit reached a stable float voltage consistent with the OEM specification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the scale complete its full power-on self-test without cutting power. Medical-grade devices run a BMS verification pass at startup — interrupting it triggers a false battery fault that sticks until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 800 Scale may not complete its boot sequence after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead-acid cells in medical scales sit at a resting voltage below the BMS boot threshold when new and unformed. The 800 Scale's controller checks terminal voltage during startup and will stall the boot if it reads below roughly 11.8V. A new cell that has self-discharged in storage may present exactly that scenario. Connecting the scale to its charger for a full charge cycle before powering on resolves this — the cell needs to reach at least 12.6V at rest before the boot sequence clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 800 Scale's charge IC applies a conservative current limit when it first sees a new cell — it cannot verify capacity until after one complete charge-discharge cycle. This means the first charge will often plateau early, showing 80–90% on the display even after several hours. Run one full discharge under normal use, then charge the battery fully overnight. After that first cycle the charge IC recalibrates and the indicator reflects accurate state-of-charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381389328474,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381389361242,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381389394010,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/american-scale-800-scale-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
