It fits the Wi-Fi enabled security camera and door monitoring unit used in residential smart home setups. Dimensions are 92.00 × 60.20 × 6.00mm — confirm against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTX-59 and TX-59+ compatibility:\u003c\/strong\u003e\n    Both variants share the same 3.7V battery bay, connector pinout, and BMS handshake protocol. A single cell covers the full TX-59 lineup 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 a TX-59 unit. The BMS accepted the cell cleanly, voltage held steady at 3.7V nominal, and protection circuits for overcharge and over-discharge triggered at expected thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNetwork re-join after power swap:\u003c\/strong\u003e\n    The TX-59 runs a mesh network re-join sequence when power is interrupted. After fitting this cell, wait at least 60 seconds before assuming a connection fault — the device needs that window to re-announce itself to your router.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTX-59 going offline immediately after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TX-59 does not reconnect to Wi-Fi the instant power is restored. The firmware runs a boot sequence and network re-join that takes up to 60 seconds under normal conditions. If the camera stays offline past that window, the router may have dropped the device lease during the power interruption. Force a router DHCP refresh or restart the camera once more — it should appear in the app within 90 seconds at 3.7V nominal charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew battery triggers a low-battery alert straight away\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement cells ship at storage voltage — typically 3.5V to 3.6V — which sits below the TX-59's alert threshold. The device reads this as a depleted battery and fires the notification immediately. Connect the unit to its charger for a full charge cycle before mounting it. Once the cell reaches 4.2V and the BMS signals full charge, the alert clears and the device reports battery status correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416139825242,"sku":"BWCS-TMX590SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416139858010,"sku":"BWCS-TMX590SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416139890778,"sku":"BWCS-TMX590SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMX590SL-1.webp?v=1779760424","url":"https:\/\/batteryweb.com\/products\/technaxx-tx-59-replacement-battery-37v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
