The TG-TXMNL is a crane remote control unit used in industrial lifting and hoist operations. Physical dimensions are 68.40 × 42.20 × 14.80mm — verify against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTG-TXMNL transmitter fit:\u003c\/strong\u003e\n    The TG-TXMNL uses a single Li-ion cell at 3.7V nominal. This replacement matches that voltage rail and connector orientation, and the BMS in the transmitter handshakes with the cell's protection circuit on power-up. OEM cross-references include D00004-02, 22.381.2, M245060, and D4-02.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated charge and discharge sequences on the bench. The onboard BMS triggered protection cutoff correctly at low-voltage thresholds, and the transmitter's power-on handshake completed without fault codes on each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInfrequent-use storage charge:\u003c\/strong\u003e\n    If the TG-TXMNL sits unused for more than four weeks, connect it to the charger for at least 30 minutes before relying on it. Li-ion cells discharged below 2.5V enter BMS lockout — the charger will appear to do nothing, and the remote will not power on.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on a freshly installed battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the TG-TXMNL sends a solenoid or relay command to the crane, the transmitter draws a short inrush current spike. If the replacement cell has a low-rated continuous discharge current or its BMS threshold is set conservatively, that spike can trip the protection circuit and cut power mid-operation. This shows as the remote going dark immediately after a control activation — not a dead battery, but a BMS trip. The fix is to ensure the replacement cell's discharge rating covers the transmitter's peak draw. This cell's BMS is rated to handle the TG-TXMNL's activation load without nuisance tripping under normal operating conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery immediately after swapping in a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6V to 3.75V, not a full 4.2V charge. The TG-TXMNL reads cell voltage and flags low battery when it sees anything below its internal threshold, which can sit above storage voltage on some firmware versions. This is not a faulty cell. Connect the battery to the transmitter's charger and run a full charge cycle before first use. Once the cell reaches 4.2V, the low-battery indicator will clear.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360062439514,"sku":"BWCS-TMX200BX-1","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360062472282,"sku":"BWCS-TMX200BX-2","price":18.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360062505050,"sku":"BWCS-TMX200BX-3","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMX200BX-1.webp?v=1778610770","url":"https:\/\/batteryweb.com\/products\/teleradio-transmitter-tele-radio-tg-txmnl-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
