It replaces OEM part numbers WP-XHT-102A and GHOTA-99G-00. Capacity is 38.48Wh — drawn directly from product specifications, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZD120B, D120D, and Apollo N1-A compatibility:\u003c\/strong\u003e\n    All three models share the same 14.8V four-cell Li-ion architecture and BMS communication protocol. The connector pinout and charge termination logic are identical across this platform, so one cell fits all three without firmware or hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the ZD120B platform. The BMS handshake completed without fault flags, and charge termination triggered correctly at 16.8V. No false low-battery alarms appeared after the first full charge-discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. Medical devices on this platform run BMS verification at startup — cutting power during that sequence triggers a false battery fault that persists until the next complete 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 on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome ZD120B and D120D units stall mid-boot when a new cell is installed straight from the box. The BMS has not yet built a charge history, so the device firmware reads the cell state as unverified and halts the sequence. This is not a faulty battery — it is a first-cycle BMS learn state. Charge the battery to full, allow the device to complete one uninterrupted boot, and the issue clears on subsequent power cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the device's charge-verification threshold is calibrated to OEM cell chemistry. A new replacement cell may read slightly below the alarm threshold on its first cycle because the internal resistance has not yet stabilised. Run one full charge-discharge cycle before clinical use — after that cycle, the BMS recalibrates its state-of-charge mapping to the new cell. If the alarm persists after two full cycles, check that the charger reached 16.8V at termination.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381447753818,"sku":"BWCS-ZAN120MD-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381447786586,"sku":"BWCS-ZAN120MD-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381447819354,"sku":"BWCS-ZAN120MD-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZAN120MD-1.webp?v=1778900958","url":"https:\/\/batteryweb.com\/products\/zondan-zd120b-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
