It fits the internal battery bay directly and matches the original voltage and capacity spec. This battery is intended for clinical and emergency-use environments where the original cell has degraded or failed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePD-1 and LS 285 compatibility:\u003c\/strong\u003e\n    Both devices share the same 12V sealed lead-acid platform, battery bay dimensions, and connector interface. The BMS on each device reads terminal voltage and internal resistance at startup — this cell matches that handshake without modification.\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 and confirmed the BMS accepted the cell, cleared the low-battery flag, and held voltage within spec under a simulated clinical load. The first cycle calibrates the charge IC to the new cell's internal resistance curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. The LS 285 and PD-1 run a BMS verification routine at boot — cutting power mid-sequence writes a false battery fault that persists 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\"\u003eDefibrillator not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PD-1 and LS 285 run a startup self-test that checks resting terminal voltage before allowing full boot. A new sealed lead-acid cell can sit below the BMS acceptance threshold if it discharged during storage — even slightly. The device interprets this as a failed or missing battery and halts the boot sequence. Connect the device to mains power first, allow the battery to charge fully, then reboot without interrupting the self-test cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge, the LS 285's charge IC applies a conservative current limit while it reads the new cell's impedance. This causes the indicator to stall — typically between 85–95% — before the algorithm adjusts. It is not a faulty cell or a faulty charger. Run one complete charge-discharge cycle and the charge IC will recalibrate; the indicator will reach 100% on the second charge. Do not use the device clinically until this first full cycle is complete.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381387952218,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381387984986,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381388017754,"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\/medimex-inc-pd-1-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
