These transmitters send zone signals to the alarm control panel — when the cell depletes, that wireless link drops. Physical dimensions are 49.60 × 16.50 × 14.50mm; confirm these match your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTX110 \/ TX120 \/ TX210 \/ TX310 transmitter fit:\u003c\/strong\u003e\n    These four models share the same C126BATTRADIO cell format, voltage rail, and connector orientation. The TX series transmitters run on a single 3.6V primary lithium cell — no charging circuit, no BMS handshake. Swap the cell and the transmitter resumes signalling immediately on the same RF channel.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We verified open-circuit voltage at 3.6V and confirmed stable current draw under simulated RF burst transmission. Li-SOCl2 cells can exhibit a temporary voltage dip on first load after long storage — this recovers within a few cycles and does not indicate a faulty cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eTX series transmitter installation tip:\u003c\/strong\u003e\n    After fitting the new cell, walk-test the zone from the panel before closing the transmitter cover. A confirmed signal receipt at the panel is faster feedback than waiting for a supervision timeout to clear.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage passivation layer in Li-SOCl2 cells after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-SOCl2 cells build a thin passivation layer on the lithium anode during storage. On first load, this layer causes a short voltage dip — sometimes as low as 3.0V — before recovering to the nominal 3.6V operating level. This is not a fault; it is a known electrochemical behaviour with this chemistry. In a TX-series transmitter, it may cause one missed RF transmission immediately after installation, which clears on the next supervision cycle without any user action.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePanel still showing zone fault after new cell is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Technoalarm control panel tracks zone supervision signals on a timed cycle — if the transmitter missed its last check-in before the cell was swapped, the panel holds the fault until the next scheduled transmission is received. Fitting the new cell does not instantly clear the log. Trigger a manual walk-test from the panel menu to force a zone poll, or wait for the next automatic supervision window. Once the panel receives a clean RF signal from the TX module, the fault clears and the zone returns to normal status.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309780861018,"sku":"BWCS-TTX110BT-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309780893786,"sku":"BWCS-TTX110BT-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309780926554,"sku":"BWCS-TTX110BT-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TTX110BT-1.webp?v=1777868465","url":"https:\/\/batteryweb.com\/products\/technoalarm-tx110-replacement-battery-36v-2600mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
