It fits the TC-3000A directly and matches the original voltage and form factor. Capacity is 1800mAh (13.32Wh), sourced from the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTC-3000A platform fit:\u003c\/strong\u003e\n    The TC-3000A runs a 7.4V two-cell Li-ion architecture. This pack matches that voltage rail and uses the same connector orientation and BMS handshake protocol the radio expects on power-up. No adapter or modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on a compatible 7.4V radio platform. The BMS held the output rail steady under PTT bursts and tripped correctly at the low-voltage cutoff threshold — no unexpected lockouts during the test cycle.\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 TC-3000A dock requires a clean contact cycle to complete the 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\"\u003eTC-3000A cutting out mid-transmission on a fresh battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion pack ships at storage voltage — typically around 3.7V per cell, not full charge. When PTT is pressed, transmit current spikes sharply. If the pack is at storage voltage, the BMS may interpret that current draw as an overcurrent event and cut the output rail. The radio drops mid-transmission, not because the pack is faulty, but because it hasn't been charged yet. Fully charge the pack in the dock before first use in the field.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTC-3000A bar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TC-3000A uses a voltage-threshold bar indicator — each bar corresponds to a voltage band, not a percentage from a fuel gauge chip. A new pack at storage voltage (around 7.4V open-circuit) will sit at a mid-range threshold and display fewer bars than a fully charged pack at 8.4V. This is normal cell behaviour, not a capacity defect. Charge the pack fully in the dock and the indicator will rise to reflect the correct voltage band.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426169520218,"sku":"BWCS-TMR100TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426169552986,"sku":"BWCS-TMR100TW-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426169585754,"sku":"BWCS-TMR100TW-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMR100TW_1.webp?v=1779930458","url":"https:\/\/batteryweb.com\/products\/tytera-tc-3000a-replacement-battery-74v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
