These units send continuous vital sign data from patients to central nursing station monitors. The OEM part numbers this cell covers are LI21I001B and 022-000196-00.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTMS60, TM80, and TMS-6016 compatibility:\u003c\/strong\u003e\n    These transmitters share the same 3.8V power rail, physical form factor, and BMS handshake protocol — one cell fits across all variants without modification to the battery bay or firmware configuration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on the TMS60 platform. The BMS accepted the new cell on first insertion, passed voltage verification, and held communication with the transmitter's charge circuit without triggering fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test procedure:\u003c\/strong\u003e\n    After installing this battery, allow the Telemetry Launcher to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window causes a false battery fault flag that persists until the next full reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Telemetry Launcher flags a battery fault on first boot after a swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMindray telemetry transmitters run a BMS handshake at startup that checks cell voltage against an OEM-calibrated threshold. A new cell arriving at partial charge from storage may read below that threshold, triggering a fault flag even though the cell is functional. This is not a defective battery — it is the device applying a conservative check tuned to a fully conditioned OEM cell. One complete charge cycle from the wall charger brings the cell into the accepted voltage window and clears the flag on next boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge of a replacement cell, the Telemetry Launcher's charge IC applies a conservative current limit while it profiles the new battery's internal resistance. This causes the charge indicator to plateau below 100% and hold there longer than expected. The device is not faulty — this behaviour resolves after the first full charge-discharge cycle as the charge IC updates its cell model. After that initial cycle, subsequent charges reach full capacity and the indicator behaves normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381452963930,"sku":"BWCS-MTS600MD-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381452996698,"sku":"BWCS-MTS600MD-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381453029466,"sku":"BWCS-MTS600MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTS600MD-1.webp?v=1778900876","url":"https:\/\/batteryweb.com\/products\/mindray-telemetry-launcher-replacement-battery-38v-3800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
