It powers the monitor during transport and patient assessment when mains power is not available. Dimensions are 182.21 x 60.74 x 23.58mm — confirm these match your battery bay before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e20100 \/ Escort II \/ Plus II platform fit:\u003c\/strong\u003e\n    These models share the same 12V sealed lead-acid voltage rail, physical form factor, and internal BMS handshake protocol, which is why a single cell covers the full compatibility range listed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the cell through a full charge cycle and monitored BMS response at load. The protection circuit held within spec across the charge and discharge curve, and the device completed its power-on self-test without flagging a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the Escort Prism monitor to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence causes a persistent false battery fault that will not clear until the next complete 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 Escort Prism alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Escort Prism's charge IC applies a conservative acceptance threshold tuned to an aged OEM cell. A new sealed lead-acid cell has a slightly different internal resistance profile during the first few cycles, and the BMS can interpret this as a failed or undercharged pack. Running one complete charge-discharge cycle lets the BMS recalibrate its capacity estimate against the new cell. After that first cycle, the low battery alarm on a fully charged pack should clear.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead-acid cells self-discharge at roughly 3–5% per month in storage. If the cell voltage drops below approximately 10.5V, the Escort Prism's BMS may refuse to initiate a boot sequence — it reads the pack as over-discharged and locks out power delivery to protect the device. Connect the monitor to mains power and leave it on charge for a full 12–16 hours before attempting to power on from battery. Once the cell recovers above the BMS recovery threshold, the monitor will boot normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381514502234,"sku":"BWCS-NK9130MD-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381514535002,"sku":"BWCS-NK9130MD-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381514567770,"sku":"BWCS-NK9130MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK9130MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/escort-prism-20100-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
