It fits the Morita Pencure LED curing light, TR-CM, TriAuto mini Endo Motor Handpiece, and TriAuto ZX. These are handheld dental devices used in clinical restorative procedures — the battery powers both the light output and the onboard electronics.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform across Morita handpieces:\u003c\/strong\u003e\n    The Pencure LED, TR-CM, and TriAuto ZX draw from the same 3.7V cell format and connector spec. The BMS in each device reads cell voltage through the same pin-out, so one cell serves the full compatibility list without modification.\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 Pencure LED platform. The onboard BMS accepted the cell, completed the charge-termination handshake at 4.2V, and the device passed its startup self-test without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this cell, allow the Pencure LED to complete its full power-on self-test without interruption. Medical device BMS firmware runs a voltage-verification routine at startup — cutting power during this sequence writes a fault state that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePencure LED alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the device BMS was calibrated to the OEM cell's charge curve. A new replacement cell hasn't yet built the voltage-history data the BMS uses to determine state of charge accurately. On the first one or two cycles, the firmware reads the cell's resting voltage conservatively and trips the low-battery threshold early. Run one complete charge-to-discharge cycle before clinical use. By the second full cycle, the BMS recalibrates its SoC estimate and the alarm behaviour normalises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePencure LED not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the cell voltage drops below approximately 2.5V, the Morita BMS enters deep-discharge lockout and will not allow the device to boot — this protects the cell from damage but it also blocks normal startup entirely. Place the device on its charger and leave it connected for at least 60 minutes before attempting power-on. The charge IC applies a trickle current to recover the cell to a voltage where the BMS will re-enable the output rail, typically around 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381452275802,"sku":"BWCS-MTZ628MD-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381452308570,"sku":"BWCS-MTZ628MD-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381452341338,"sku":"BWCS-MTZ628MD-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTZ628MD-1.webp?v=1778900958","url":"https:\/\/batteryweb.com\/products\/morita-pencure-led-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
