It replaces OEM part numbers BP-88, BP-88S, BP-308, BP-508, BP-608, and compatible Yuasa cell references. Physical dimensions are 143 x 62 x 21mm — confirm fitment against the original before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eADVANTAGE and ASM 5000 platform compatibility:\u003c\/strong\u003e\n    These models share the same 12V power rail, physical battery bay dimensions, and connector pinout. The BMS in each unit communicates charge state using the same handshake protocol, so one cell pack covers the full listed range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Colin Medical platform to verify BMS acceptance. The charge IC recognised the cell correctly, the self-test passed on the second cycle, and the protection circuit tripped at the expected low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full startup self-test without interruption. Colin Medical monitors run a BMS verification sequence at boot — cutting power mid-sequence registers a false battery fault 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\"\u003eWhy the ADVANTAGE alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BMS in Colin Medical monitors stores a charge profile from the previous cell. When a new Ni-MH pack is installed, the internal resistance reading does not match the stored OEM baseline, and the monitor interprets this as a weak or failing battery. This is not a fault in the replacement cell — it is a learn-cycle artefact. Run one complete charge-to-discharge-to-full-recharge cycle before clinical use. After that cycle, the BMS recalibrates its threshold and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day. A pack stored for several months can drop below the BMS recovery threshold — typically around 9V on a 12V Ni-MH pack — at which point the protection circuit blocks output entirely. The device appears completely dead even though the cell is not damaged. Place the battery on a standalone Ni-MH charger until it reaches at least 11V, then reinstall and power on the monitor normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467283546,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381467316314,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381467349082,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/colin-medical-advantage-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
