It powers the light source, imaging electronics, and onboard processing during diagnostic procedures. Voltage, connector geometry, and cell count match the original battery pack configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDefiscope DS and Defigard 3002 \/ 3002 IH platform:\u003c\/strong\u003e\n    These three models share the same 14.4V battery rail, connector pinout, and BMS communication protocol. A single cell pack revision covers all three without any adapter or wiring modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a clinical-load profile. The BMS accepted the new cells, completed the handshake, and held voltage within the device's operational window across the full discharge curve. No false fault codes were triggered after the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use self-test protocol for clinical devices:\u003c\/strong\u003e\n    After installation, allow the Defiscope DS or Defigard 3002 to complete its power-on self-test cycle without interruption. The BMS runs a chemistry verification at startup — cutting power during this sequence registers a false battery fault that persists until the next full 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 Defigard 3002 flags a battery fault on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Defigard 3002 charge IC applies a conservative acceptance threshold calibrated to an aged OEM cell. A fresh Ni-MH pack presents a slightly different internal resistance profile on the first charge, which the IC can misread as a fault condition. This is not a defective battery. Run one complete charge-to-discharge cycle before relying on the battery indicator reading. After that cycle, the charge IC recalibrates its internal reference and reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn a fresh Ni-MH cell, the charge termination logic on the Defiscope DS and Defigard 3002 can trigger early because the delta-V slope of a new pack differs from a broken-in one. The charger reads the inflection point as full-charge termination before the pack is truly at capacity. Remove the battery, wait two minutes, and re-seat it to restart the charge cycle. After one full charge-discharge cycle, the termination voltage aligns correctly and the indicator will reach 100%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381481013338,"sku":"BWCS-BKR300MD-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381481046106,"sku":"BWCS-BKR300MD-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381481078874,"sku":"BWCS-BKR300MD-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKR300MD-1.webp?v=1778901171","url":"https:\/\/batteryweb.com\/products\/schiller-defiscope-ds-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
