It carries a 2000mAh (36Wh) capacity and fits the B-TC650-SC directly. Used in electrical installation and cable processing work where a dead battery halts the job.\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 architecture with a BMS that monitors cell voltage and inrush current during each crimp cycle. This replacement pack matches that voltage rail and connector orientation so the tool's BMS handshake completes without error codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through repeated crimp cycles and confirmed the BMS holds the voltage rail steady through motor-start inrush. Overcurrent protection tripped correctly at threshold — no nuisance cutoffs under normal crimping load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use conditioning on a crimping tool:\u003c\/strong\u003e\n    On first use, run the B-TC650-SC at partial load for two full crimp cycles before moving to maximum force applications. This allows the BMS to profile the motor's inrush current signature before locking its overcurrent protection thresholds.\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 trigger pull during heavy crimping duty\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe B-TC650-SC draws a sharp current spike the instant the crimp cycle starts — this inrush can hit several times the steady-state draw. A new pack or a pack coming out of storage has not yet profiled that spike, so the BMS may read it as a fault and cut power mid-cycle. Running two partial-load cycles gives the BMS enough data to distinguish a normal motor-start transient from a genuine overcurrent event. After conditioning, the cutoff threshold stabilises and nuisance trips stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not accepting the pack after extended storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack sits long enough, cell voltage drops below the charger's acceptance window — typically under 2.5V per cell — and the charger refuses to begin a charge cycle, showing a fault or no response. Place the pack on the charger and leave it for 10–15 minutes; many chargers include a trickle-recovery mode that nudges cells back above the acceptance threshold before switching to full charge. If the charger still rejects the pack after 20 minutes, check each cell group with a multimeter — any cell below 2.0V indicates permanent degradation and the pack should be replaced.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416015437914,"sku":"BWCS-MTB180VX-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416015470682,"sku":"BWCS-MTB180VX-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416015503450,"sku":"BWCS-MTB180VX-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTB180VX-1.webp?v=1779759486","url":"https:\/\/batteryweb.com\/products\/cembre-b-tc650-sc-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
