Both units run the same 11.1V three-cell architecture and use an identical connector and BMS handshake, so a single cell SKU covers both platforms. Capacity is rated at 2600mAh (28.86Wh), matching OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApollo N5 and ZD120D platform fit:\u003c\/strong\u003e\n    Both models share the same voltage rail, physical connector, and BMS communication protocol. The battery management system on each device authenticates cell chemistry at boot — this replacement passes that handshake without modification or firmware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, boot, and load sequences on compatible hardware. The BMS completed its initialisation routine, accepted the charge profile, and did not throw a fault code at any point during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test behaviour after installation:\u003c\/strong\u003e\n    After fitting this cell, allow the Apollo N5 to complete its full power-on self-test without interruption. Medical devices run a BMS verification routine at startup — cutting power mid-sequence can trigger a persistent battery fault that survives until the next full reboot cycle.\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 on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Apollo N5 and ZD120D run a staged boot that includes a BMS query before the main OS loads. If the cell voltage is below approximately 10.5V — which is common after shipping — the device may halt at the hardware check screen rather than completing startup. This is a low-voltage lockout, not a faulty cell. Connect the charger first and bring the cell above 11.0V before attempting to power on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge after installation, the device's charge IC applies a conservative current limit while it calibrates against the new cell's internal resistance. This often results in the indicator stalling between 90% and 98% before the session ends. It is not a capacity defect. Run one complete charge-discharge cycle and the calibration corrects — subsequent charges will terminate at full capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381448015962,"sku":"BWCS-ZAN500MD-1","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381448048730,"sku":"BWCS-ZAN500MD-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381448081498,"sku":"BWCS-ZAN500MD-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZAN500MD-1.webp?v=1778900958","url":"https:\/\/batteryweb.com\/products\/zondan-apollo-n5-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
