It fits the Vitalogik 4500 directly, matching the OEM part number TSGLIIO100298. The Vitalogik 4500 monitors heart rate, SpO2, and blood pressure at the bedside and during patient transport.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVitalogik 4500 platform fit:\u003c\/strong\u003e\n    The Vitalogik 4500 runs a proprietary BMS handshake that authenticates cell chemistry at 14.8V nominal. This replacement uses matched lithium-ion cells at the same voltage rail and connector pinout, so the BMS handshake completes without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Vitalogik 4500 power-on self-test sequence. The BMS reached full charge acceptance and cleared all battery status flags within two full charge-discharge cycles. No thermal events or cutoff trips were recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the Vitalogik 4500 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence writes a false battery fault to memory that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vitalogik 4500 runs a multi-stage boot sequence that includes a battery authentication check before the monitoring software loads. A new cell that hasn't completed its first full charge cycle may present a state-of-charge reading the BMS flags as insufficient for boot clearance. This is a threshold check, not a hardware fault. Charge the battery fully before the first install, then allow the device to boot without interruption — the sequence completes once the BMS logs an authenticated full-charge event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle, the Vitalogik 4500's charge IC applies a conservative current limit to new lithium-ion cells while it profiles internal resistance. The display may hold at 95–99% for an extended period before the final trickle phase completes. This is normal behaviour and not a sign of a defective cell. Let the charge cycle finish uninterrupted — the indicator will reach 100% and the charge IC will log the full-capacity baseline for future cycles.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381466202202,"sku":"BWCS-CKV450MD-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381466234970,"sku":"BWCS-CKV450MD-2","price":113.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381466267738,"sku":"BWCS-CKV450MD-3","price":124.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CKV450MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/charter-kontron-vitalogik-4500-replacement-battery-148v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
