These pumps deliver nutritional formula at precise flow rates, and the battery powers the motor mechanism during ambulatory or backup operation. Replace this cell when the pump alarms low battery prematurely or fails to hold a charge through a full feed cycle.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKangaroo 224, 321, 324, and K524 compatibility:\u003c\/strong\u003e\n    All four pump models share the same 7.2V battery rail, connector format, and BMS handshake protocol — one cell fits the full platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the Kangaroo platform and confirmed the BMS accepts the cell on first installation, completes charge termination correctly, and does not trigger a false low-battery fault under normal motor load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test handling:\u003c\/strong\u003e\n    After installing this battery, let the pump complete its full power-on self-test without interruption. The BMS runs a chemistry verification at startup — cutting power mid-sequence locks in 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\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Kangaroo pump's BMS compares cell voltage against a threshold calibrated to the original OEM cell's charge curve. A new Ni-MH cell fresh out of the box has a slightly different internal resistance profile, so the first charge cycle may not push the terminal voltage high enough to clear the alarm threshold. This is not a cell defect — it resolves after one complete charge-discharge cycle. Run the pump on battery until it shuts down naturally, then charge fully before clinical use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePump will not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and if the cell voltage drops below approximately 5.4V, the pump's BMS will not initiate a charge cycle — it reads the cell as potentially damaged and locks out. Connect the pump to mains power and leave it on charge for at least four hours without pressing any buttons. Most BMS controllers on this platform will re-initialise the charge IC once the cell recovers above 6.0V and resume normal charging from there.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381500444762,"sku":"BWCS-KNG224MD-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381500477530,"sku":"BWCS-KNG224MD-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381500510298,"sku":"BWCS-KNG224MD-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KNG224MD-1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/sherwood-kangaroo-224-feeding-pump-replacement-battery-72v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
