The IND221 is a field-portable display unit that connects to industrial scales and load cells in production and quality control environments. When the original pack no longer holds a charge through a full shift, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIND221 pack fitment:\u003c\/strong\u003e\n    The IND221 uses a 7.2V Ni-MH cell configuration with a specific connector orientation and BMS handshake that matches this pack's discharge profile. Swapping to a mismatched voltage rail causes the indicator to flag a power fault before it reaches the home screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge and load cycle on the IND221 platform. The BMS accepted the charge without fault codes, and the indicator cycled through its startup sequence and scale-zero routine without a voltage dropout event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration step:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the IND221 menu before taking it to the floor. The indicator maps battery state during calibration — skipping this step causes premature low-battery warnings during the first weighing session, even with a full charge.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIND221 shutting down mid-weighing session with a charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe IND221 draws a brief current spike each time it polls the load cell, especially on units with active filtering enabled. If the battery cells have aged or a new pack hasn't been calibrated into the system, that spike can push the instantaneous draw past the BMS cutoff threshold. The indicator reads this as a fault and cuts power rather than displaying a measurement. Fitting a fresh pack and completing the calibration cycle through the setup menu resolves the cutoff in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eIND221 not recognising a new pack after the unit sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge over storage, and if the pack voltage drops below roughly 5.0V the IND221's charge circuit treats it as an invalid cell and refuses to initiate charging. Connect the unit to mains power and leave it on charge for a minimum of 30 minutes before expecting the indicator to respond. If the charge LED remains dark, disconnect and reconnect the charger to force a re-initialisation of the charge controller. Once the pack recovers above the acceptance threshold, charging proceeds normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360572604506,"sku":"BWCS-MTL221SL-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360572637274,"sku":"BWCS-MTL221SL-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360572670042,"sku":"BWCS-MTL221SL-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTL221SL-1.webp?v=1778616005","url":"https:\/\/batteryweb.com\/products\/mettler-toledo-ind221-replacement-battery-72v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
