It fits the Injectionomat platform directly and restores battery-backed operation to the pump when the original cell depletes or fails. Voltage, capacity, and connector match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInjectionomat platform fit:\u003c\/strong\u003e\n    The Agilia Injectionomat uses a 6V Ni-MH cell with a BMS handshake that monitors cell chemistry and voltage rail. Swapping to a different voltage or chemistry causes an immediate fault state — this cell matches both to avoid that.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Injectionomat's power-on self-test sequence and monitored the BMS response at each charge threshold. The cell passed self-test verification after one full conditioning cycle without triggering a false fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the Injectionomat complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence causes 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 Injectionomat alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Injectionomat's BMS stores a reference profile for the OEM cell's charge curve. A new replacement cell has a slightly different internal resistance signature on the first cycle, and the BMS interprets that deviation as insufficient charge. This is not a fault with the battery — it is the BMS applying its original calibration to an unconditioned cell. Run one full charge-discharge cycle before clinical use. After that first cycle, the BMS resets its threshold and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eInjectionomat not powering on after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge in storage, and the Injectionomat's BMS has a minimum recovery threshold — typically around 5.4V for a 6V pack. If the cell voltage drops below that threshold, the BMS will not allow startup, and the device appears completely dead. This is not permanent. Connect the pump to mains power and leave it on charge for at least two hours before attempting to power on. If the charge indicator responds, the cell is recovering — allow the full charge cycle to complete before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381501296730,"sku":"BWCS-FRV238MD-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381501329498,"sku":"BWCS-FRV238MD-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381501362266,"sku":"BWCS-FRV238MD-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FRV238MD-1.webp?v=1778901305","url":"https:\/\/batteryweb.com\/products\/agilia-injectionomat-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
