These devices are used in professional broadcast and video production environments where power continuity matters. Capacity figures come from the product specification: 1500mAh \/ 11.1Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC-2U, UC-PD1, and UC-PD2 compatibility:\u003c\/strong\u003e\n    All three units share the same 7.4V two-cell Li-ion architecture and connector format. The BMS voltage thresholds and charge termination behaviour are consistent across this product family, which is why a single cell replacement covers all three.\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 bench and confirmed the BMS accepted the replacement without fault flags. Charge termination triggered correctly at full capacity with no overcharge events recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on the UC-PD1 and UC-PD2:\u003c\/strong\u003e\n    Run one full charge cycle through the OEM charger or the camera body before heavy production use. Some IDX BMS firmware requires this initial cycle to calibrate the battery-remaining display and map the new cell's discharge curve accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage display showing wrong values after fitting a replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MC-2U and related units read state-of-charge by mapping voltage to a stored discharge curve. A new Li-ion cell has a slightly different resting voltage profile at each charge level compared to an aged original. Until the BMS recalibrates, the percentage shown on the unit can read high or low relative to actual charge. Running one complete discharge-to-cutoff followed by a full recharge typically resolves this. After that cycle, the indicator tracks the new cell's actual discharge curve instead of the old one.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body showing no battery or incompatible battery on a valid replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's authentication handshake does not receive an expected response from the cell on first insertion. The fix is straightforward: remove the battery, insert it again, then place it on charge via the OEM charger for at least 15 minutes before powering the unit on. This sequence lets the BMS initialise fully and pass the handshake at the correct voltage — typically 7.4V nominal. After that, the unit recognises the cell without further prompting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333809799258,"sku":"BWCS-FV70-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333809832026,"sku":"BWCS-FV70-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333809864794,"sku":"BWCS-FV70-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FV70-1.webp?v=1778213246","url":"https:\/\/batteryweb.com\/products\/idx-system-mc-2u-replacement-battery-74v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
