It matches OEM part numbers 179033-R0, BATT\/110320, MB1790, and 88888749. The same cell fits the broader Fresenius Volumat pump platform where those part numbers cross-reference.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVolumat Agilia platform fit:\u003c\/strong\u003e\n    The Agilia and Agilia D share the same 7.4V power rail, connector pinout, and BMS communication protocol. A single battery SKU covers both variants because the charge IC expects identical cell chemistry and voltage thresholds across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the Volumat Agilia platform and logged BMS handshake, charge acceptance, and cutoff behaviour. The protection circuit triggered correctly at low-voltage cutoff and accepted a full charge to 8.4V without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, allow the pump to complete its full power-on self-test without interruption. The Volumat Agilia runs a BMS verification sequence at startup — cutting power during this window 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 Volumat Agilia alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe pump's BMS stores capacity thresholds calibrated to the original cell's charge history. A new replacement cell has no cycle data, so the BMS cannot yet verify it meets the internal pass threshold. This triggers a low-battery alarm even when the cell sits at full voltage. One complete charge-discharge cycle lets the BMS record actual capacity data and clears the alarm on subsequent boots.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVolumat Agilia fails to complete boot sequence after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If a replacement battery has been on a shelf for several months, its resting voltage may fall below the pump's BMS recovery threshold — typically around 6.0V for a 7.4V nominal pack. Below that threshold, the BMS locks out the discharge path and the pump will not boot. Connect the battery to a compatible charger first and allow it to recover to at least 7.0V before installing it in the pump.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381497167962,"sku":"BWCS-FVA033MD-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381497200730,"sku":"BWCS-FVA033MD-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381497233498,"sku":"BWCS-FVA033MD-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FVA033MD-1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/fresenius-infusionspump-volumat-agilia-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
