It fits the UV3R, UV-3R, BF-T6, and C5 handheld two-way radios. Slot it in where the original BL-3 sat and the radio powers on normally.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUV3R and BF-T6 platform fit:\u003c\/strong\u003e\n    Both radios share the same BL-3 slot dimensions, 3.7V nominal rail, and contact layout. One pack covers either unit without adapters or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a transmit cycle on the UV3R. The BMS held stable through repeated PTT presses and did not trigger overcurrent cutoff under normal TX load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst contact insertion on the UV3R charger cradle:\u003c\/strong\u003e\n    If the cradle LED flashes or shows a fault on first insertion, remove the pack, wipe the three contact pads on the battery with a dry cloth, and reseat firmly. The cradle needs a clean contact cycle to read the new pack's BMS state before it begins charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the UV3R cuts out when you hold PTT on a fresh BL-3\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new BL-3 ships at storage voltage — typically around 3.6V to 3.65V, not a full 4.2V charge. When you press PTT, the UV3R draws a short current spike to drive the RF output stage. At storage voltage, internal cell impedance is slightly higher, and the BMS may interpret that spike as an overcurrent event and cut the pack. Charge the battery fully in the cradle before first transmit use. Once at 4.2V, the spike sits well within the BMS threshold and cutout stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUV3R bar indicator drops one bar immediately after inserting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe UV3R uses a simple voltage-threshold bar display — it reads resting cell voltage and maps it to bars. A new pack at storage voltage (around 3.6V) sits one threshold below a freshly charged cell at 4.2V, so the radio shows one fewer bar than expected. This is not a fault with the pack. Charge the battery fully in the cradle until the LED goes green, then reinsert — the indicator will read the correct bar level against the 4.2V resting voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426282766426,"sku":"BWCS-BAF300TW-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426282799194,"sku":"BWCS-BAF300TW-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426282831962,"sku":"BWCS-BAF300TW-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BAF300TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/baofeng-uv3r-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
