It replaces a depleted or dead pack and restores the tool to full operating voltage. Capacity is 3000mAh (54Wh) — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eB-TC650-SC platform fit:\u003c\/strong\u003e\n    The B-TC650-SC runs an 18V rail with a dedicated BMS handshake that controls discharge cutoff during high-torque crimping cycles. This pack matches that voltage rail and connector interface so the tool's protection circuit recognises it without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated high-current discharge draws simulating crimping inrush loads. The BMS held the overcurrent threshold correctly and did not trip on clean trigger pulls.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for crimping tools:\u003c\/strong\u003e\n    On first use, run the tool at partial load for two cycles before attempting full crimping pressure. This lets the BMS profile the motor's inrush current draw and set overcurrent protection thresholds before you hit maximum torque demands.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on the B-TC650-SC during the crimp stroke\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe B-TC650-SC draws a sharp inrush spike the instant the crimp mechanism engages under load. If the BMS overcurrent threshold is set conservatively — common on a new or freshly stored pack — that spike can trip the protection circuit mid-stroke. The tool stops abruptly, not from a dead battery but from a BMS interrupt. Two or three light break-in cycles recalibrate the threshold. After that, the pack handles full crimping loads without tripping.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack drops below approximately 2.5V per cell, most chargers refuse to begin a charge cycle — the voltage is too low for the charger's acceptance window. The charger either blinks an error or stays dark. A compatible charger with a recovery or \"wake\" mode can trickle-charge the pack back above 3.0V per cell, at which point normal charging resumes. Check cell voltage with a multimeter before assuming the pack is dead — recovery is often possible above 2.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416051253338,"sku":"BWCS-MTK570PW-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416051286106,"sku":"BWCS-MTK570PW-2","price":72.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416051318874,"sku":"BWCS-MTK570PW-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTK570PW-1.webp?v=1779759859","url":"https:\/\/batteryweb.com\/products\/cembre-b-tc650-sc-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
