It fits the same footprint as the original cell at 178.00 x 66.60 x 35.00mm and connects to the existing wiring harness without modification. If the device is alarming low battery or failing to hold charge, this is the direct cell replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDeluxe Model 10 fit:\u003c\/strong\u003e\n    The Model 10 draws a stable low-current load across its operating cycle, which suits sealed lead-acid chemistry. The BMS in this device is calibrated for 12V SLA voltage curves — swapping to a different chemistry without recalibrating the charge IC will trigger false low-battery faults.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence and confirmed the BMS accepted the cell and completed its self-test handshake without triggering a fault flag at any point in the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interrupting the sequence. The Model 10 runs a BMS verification routine at startup — cutting power during this window writes a fault state that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Deluxe Model 10 fails its self-test after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Model 10 runs an internal BMS verification at every startup. This routine checks that the cell voltage matches expected thresholds for a fully charged SLA cell — typically 12.6V to 12.8V at rest. A new cell that has partially self-discharged during storage may come in below that window. The device then logs a self-test failure, not because the battery is faulty, but because the BMS threshold was not met. Charge the replacement cell fully before first installation and allow resting voltage to stabilise before powering the device on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge IC in medical-grade devices applies a conservative current limit when it detects a new or deeply discharged cell. This is intentional — it prevents voltage spiking on a cold cell. The visible result is a charge indicator that stalls at 85–95% for an extended period before completing. This is not a charger fault or a cell defect. Run one full charge cycle to completion and the IC will recalibrate its termination threshold to the new cell's internal resistance profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381387362394,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381387395162,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381387427930,"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\/deluxe-10-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
