It fits the Apnoescreen directly, replacing OEM part numbers 110129, 806524, and A0-61. The Apnoescreen runs overnight patient monitoring sessions, so battery condition directly affects diagnostic data integrity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApnoescreen battery platform:\u003c\/strong\u003e\n    The Apnoescreen uses a 6V Ni-Cd cell pack with a BMS that verifies chemistry and internal resistance at startup. Ni-Cd is specified here because the device charge controller applies a trickle and delta-V termination sequence tuned to nickel chemistry — a lithium cell will not handshake correctly with this charge IC.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Apnoescreen's charge-discharge sequence and confirmed the BMS accepted the cell, completed its self-test without fault codes, and held voltage within spec under the device's monitoring load profile across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Apnoescreen to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at every startup. Cutting power during that sequence causes a battery fault flag that persists until the next clean, uninterrupted reboot — not a cell fault, a sequence fault.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Apnoescreen charge indicator stalls below 100% on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Apnoescreen's charge IC applies a conservative current limit when it detects a new or long-stored Ni-Cd cell with elevated internal resistance. The charge algorithm interprets higher resistance as a partially degraded cell and backs off the charge rate before delta-V termination fires. This means the indicator may stall at 80–90% on the first charge. One complete charge-discharge cycle conditions the cell, lowers internal resistance, and the charge IC will reach full termination correctly on the second cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApnoescreen not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-Cd cells self-discharge at roughly 15–20% per month at room temperature. A cell that has been in storage for several months can drop below the BMS recovery threshold — typically around 4.8V for a 6V pack — and the device will not power on at all. This is not a dead cell; it is a BMS lockout. Connect the charger and leave it for a full charge cycle without attempting to power on the device. Once the pack climbs back above the 4.8V recovery threshold, the BMS releases the lockout and the device boots normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381373665370,"sku":"BWCS-JRA524MD-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381373698138,"sku":"BWCS-JRA524MD-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381373730906,"sku":"BWCS-JRA524MD-3","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JRA524MD-1.webp?v=1778900448","url":"https:\/\/batteryweb.com\/products\/jaeger-apnoescreen-replacement-battery-6v-3000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
