It uses OEM part number TEB-4000 and fits the TE320 portable handset used across security, construction, hospitality, and emergency services roles. Swap it in when the original pack no longer holds a charge through a full shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTE320 platform fit:\u003c\/strong\u003e\n    The TE320 runs a 3.8V single-cell Li-ion architecture with a fixed connector footprint and BMS handshake. This pack matches that voltage rail and connector geometry, so the radio's charge circuit recognises it without firmware flags or indicator errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and load discharge on the TE320 platform. The BMS handled transmit-current spikes cleanly and did not trigger overcurrent lockout during sustained PTT sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The TE320 dock requires a clean contact cycle to accept the new BMS handshake before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TE320 drops to reduced TX power mid-shift on a new TEB-4000\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6V to 3.65V, not a full 3.8V charge. The TE320 monitors rail voltage under RF load, and if it sags below the radio's TX power threshold during a long transmission, the radio steps down output power automatically. This is not a faulty pack — it is the radio protecting its finals under a partially charged cell. Charge the pack fully to 4.2V before the first shift and the behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after inserting TEB-4000\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TE320 reads battery state through voltage thresholds, not a fuel gauge chip. A new pack at storage voltage sits near the threshold between the top two bar levels, so the display shows one bar fewer than a freshly charged pack would. This is a voltage reading, not a capacity fault. Put the pack on the dock for a full charge cycle and the indicator will read correctly at 4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426219458650,"sku":"BWCS-TXE320TW-1","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426219491418,"sku":"BWCS-TXE320TW-2","price":70.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426219524186,"sku":"BWCS-TXE320TW-3","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TXE320TW-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/telox-te320-replacement-battery-38v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
