It fits the CM-N5000, CM-N3000, and CM-N4000 models using OEM part number UF18500F-TU-C. The battery slots into the same housing as the original and connects to the same BMS handshake the device expects at startup.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCM-N3000 \/ CM-N4000 \/ CM-N5000 compatibility:\u003c\/strong\u003e\n    These three Hada Crie models share the same cylindrical 18500-format cell, 3.7V nominal rail, and connector pinout. One battery covers all three because the BMS protection profile and charge termination voltage are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a Hada Crie unit. The BMS accepted the cell without triggering a protection fault, and the device completed its standard ionic and vibration cycles without voltage sag or cutoff at the 3.7V nominal load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMoisture exposure precaution:\u003c\/strong\u003e\n    Dry the charging port fully before connecting after use near water. Moisture bridging the charging contacts can trigger a BMS protection fault that presents as a completely dead battery rather than a charging error — the device won't respond until the fault clears and the port is dry.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery fade from daily top-up charging on the Hada Crie\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePlugging the Hada Crie in after every short session without running the battery down is the fastest way to degrade cell capacity. Lithium-ion cells cycled repeatedly between 80–100% accumulate plating stress at the anode, which shortens overall capacity faster than full cycles would. The Hada Crie has no battery conditioning mode, so the BMS fuel gauge also drifts — the device may show adequate charge and then cut out early. Letting the battery discharge to the low-indicator point before charging once a week keeps the gauge accurate and reduces plating stress.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHada Crie motor output drops before the low-battery indicator appears\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe ionic motor and vibration head draw a short current spike on startup that causes voltage to sag momentarily below the BMS reporting threshold. On a degraded or partially discharged cell, this sag is enough to reduce motor speed noticeably even though the indicator hasn't triggered yet. The BMS reads resting voltage, not load voltage, so the indicator lags behind what the motor actually experiences under draw. If the device vibrates weakly but the indicator shows charge remaining, measure resting cell voltage — a healthy cell at partial charge should read above 3.6V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415958716506,"sku":"BWCS-HCM500SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415958749274,"sku":"BWCS-HCM500SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415958782042,"sku":"BWCS-HCM500SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HCM500SL-1.webp?v=1779758583","url":"https:\/\/batteryweb.com\/products\/hitachi-hada-crie-replacement-battery-37v-1600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
