It fits directly in place of OEM part 400-316. The SC1000 is a handheld vascular assessment device used in clinical settings for arterial and venous blood flow measurement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSC1000 platform fit:\u003c\/strong\u003e\n    The SC1000 uses a 12V Ni-MH pack with a specific cell count and connector orientation tied to its onboard charge IC. This replacement matches that voltage rail and connector, so the device's BMS handshake completes at startup without throwing a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full charge-discharge cycle on the SC1000 and confirmed the BMS accepted the new cell without flagging a chemistry mismatch. Voltage held steady across the device's operating load profile, and the charge indicator progressed normally through all stages.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the SC1000 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence can trigger a persistent battery fault flag that won't clear until the next complete 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 SC1000 reports low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SC1000's charge IC uses a threshold calibrated to the charge history of the installed cell. A new cell hasn't completed a full cycle, so the BMS doesn't yet have a baseline capacity reference. Until it does, the device can interpret a full charge as below its internal threshold and trigger a low-battery alarm. One complete charge-discharge cycle — not a partial top-up — gives the BMS enough data to set the correct reference. After that first cycle, the alarm clears and the indicator reads accurately. Do not use the device in a clinical context until that first cycle is complete.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSC1000 fails to power on after the replacement battery sat 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 battery that has been in storage for several weeks can drop below 9V, which is under the SC1000's BMS recovery threshold. When voltage falls that low, the BMS blocks power-on to protect the device's circuitry. Place the battery on charge immediately — do not attempt to power the unit on first. Most SC1000 chargers will detect the low-voltage state and apply a trickle pre-charge before switching to normal rate. Once the pack reaches approximately 10.8V, the BMS releases the lockout and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381452767322,"sku":"BWCS-HTC100MD-1","price":111.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381452800090,"sku":"BWCS-HTC100MD-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381452832858,"sku":"BWCS-HTC100MD-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTC100MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/huntleigh-sc1000-replacement-battery-12v-3500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
