It matches the OEM part number AA14.1 and fits the original battery compartment without modification. Capacity figure is taken from product specification: 2000mAh (28.8Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSingle Micro and ZD-50C6 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V Ni-MH battery platform, share an identical connector and BMS handshake protocol, and draw from the same charge management IC. One battery covers both units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this cell under a simulated infusion pump load profile. The BMS passed the self-test sequence on each run and held voltage within the accepted operating band across all cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the pump to complete its full power-on self-test without interruption. Zede injection pumps run a BMS verification routine at startup — cutting power during this sequence trips 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\"\u003eDevice not completing boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Zede pump's BMS checks cell voltage and chemistry fingerprint during the boot sequence before it will release the motor drive circuit. A freshly fitted Ni-MH cell that has partially self-discharged in storage can fall below the BMS boot threshold, causing the device to hang or restart mid-sequence. This is not a faulty battery — it is a low starting voltage problem. Charge the new battery fully before the first installation, and confirm the cell reads at least 14.4V at the terminals before fitting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately on a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first installation, the pump's charge controller has no capacity history for the new cell and applies conservative BMS thresholds calibrated to a broken-in OEM cell. A new Ni-MH cell has slightly lower initial charge acceptance, which the BMS can read as a partial charge even after a complete charge cycle. Run one full charge-to-discharge-to-charge cycle before clinical use — this allows the BMS to complete its learn cycle and update the low-battery trigger to the correct threshold for this cell's actual capacity. After that first conditioning cycle, the alarm behaviour normalises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381425209434,"sku":"BWCS-ZDZ506MD-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381425242202,"sku":"BWCS-ZDZ506MD-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381425274970,"sku":"BWCS-ZDZ506MD-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZDZ506MD-1.webp?v=1778900681","url":"https:\/\/batteryweb.com\/products\/zede-single-micro-injection-pump-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
