It fits the handheld radio directly, restoring power to units where the original cell no longer holds adequate charge. Voltage and cell chemistry match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLiberty Mic platform fit:\u003c\/strong\u003e\n    The Liberty Mic runs a 2.4V dual-cell Ni-MH architecture with a compact form factor — 46.46 x 23.00 x 10.61mm. This replacement matches that envelope and contact layout, so the pack seats and connects without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit and receive loads on the bench. The BMS handled PTT-triggered current spikes without tripping, and charge acceptance from the dock was consistent across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault or refuses to initiate charging on first insertion, remove the pack, wipe the contact pads with a dry cloth, and reseat firmly. The Liberty Mic dock requires a clean contact cycle to recognise the new pack 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 Liberty Mic cuts out mid-transmission on a freshly inserted BT-914\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage — typically 1.0–1.1V per cell, which puts this 2.4V pack well below its nominal operating level. When PTT is pressed, the radio draws a short high-current burst for RF output. A cell at storage voltage sags further under that load, and the radio's low-voltage cutoff triggers before the transmission completes. This is not a fault with the pack — it is the expected behaviour of an uncharged Ni-MH cell under transmit load. Run a full charge cycle before placing the radio back in service.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing fewer bars than expected after fitting a new BT-914\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Liberty Mic uses a simple voltage-threshold bar indicator — it reads resting voltage and maps it to a bar count. A new pack at storage voltage reads low on that scale, so the indicator may show one or two bars even though the cell is not discharged. This is not a capacity fault. After a full charge cycle, resting voltage rises to approximately 2.4–2.5V and the indicator returns to full. Do not judge the pack's condition until at least one complete charge and discharge cycle is finished.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426294562906,"sku":"BWCS-UBC906TW-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426294595674,"sku":"BWCS-UBC906TW-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426294628442,"sku":"BWCS-UBC906TW-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UBC906TW-1.webp?v=1779930602","url":"https:\/\/batteryweb.com\/products\/president-liberty-mic-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
