It fits the handheld unit used to operate overhead cranes and lifting equipment via wireless control. Rated at 6.66Wh and sized at 68.40 × 42.20 × 14.80mm to seat correctly inside the transmitter housing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTG-TXMNL transmitter compatibility:\u003c\/strong\u003e\n    This cell matches the voltage rail and physical footprint of the TG-TXMNL platform. OEM references D00004-02, 22.381.2, M245060, and D4-02 all map to the same cell specification used across the TG-TXMNL transmitter series.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on the TG-TXMNL transmitter and confirmed the BMS accepted the cell without fault flags. Solenoid activation events during testing did not trigger power dropout at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eIdle storage charge interval:\u003c\/strong\u003e\n    Crane remotes often sit unused for weeks. Charge this battery at least once per month during idle periods — Li-Polymer cells discharged below 2.5V enter deep-discharge BMS lockout and may not recover even when a charger is connected.\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 swapped battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a crane remote activates a solenoid or relay, there is a short inrush current spike that the battery must supply without the voltage sagging below the BMS cutoff threshold. A cell at storage voltage — typically around 3.6V — has less headroom to absorb that spike than a fully charged cell at 4.2V. The BMS interprets the sag as a fault condition and cuts output to protect the cell. Always charge the replacement battery to full before first use in the transmitter to avoid this trip.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low-battery warning immediately after new cell install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells ship at storage voltage, typically 3.6–3.7V, not at full charge. The TG-TXMNL transmitter reads cell voltage and displays a low-battery indicator when voltage sits below its threshold, which can trigger even on a brand-new cell straight out of packaging. This is not a faulty battery — it is a cell that has not yet been charged. Connect the transmitter to its charger and bring the cell to 4.2V before treating the indicator as a defect.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360061096026,"sku":"BWCS-TMX200BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360061128794,"sku":"BWCS-TMX200BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360061161562,"sku":"BWCS-TMX200BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMX200BL-1.webp?v=1778610770","url":"https:\/\/batteryweb.com\/products\/teleradio-transmitter-tele-radio-tg-txmnl-replacement-battery-37v-1800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
