It matches OEM part numbers ICP083448 and JHHY903448A. The cell footprint is 47 × 40 × 10.10mm — measure your existing pack before ordering if the housing has been opened previously.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTectalk Float and Bambini Babysitter compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V single-cell LiPo architecture, connector pinout, and BMS voltage thresholds, which is why one pack covers the whole group. Swapping between them requires no wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and PTT-triggered transmit cycles on the Tectalk Float. The BMS held within spec during the transmit current spike and returned cleanly to standby draw without latching into overcurrent lockout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion after storage:\u003c\/strong\u003e\n    If the charger LED blinks or the radio shows no bar indicator on first use, wipe the gold contact pads on the battery with a dry cloth and reseat firmly. LiPo cells shipped at storage voltage — around 3.7–3.8V — can sit just below the charger's acceptance threshold until a clean contact cycle triggers the BMS handshake.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTectalk Float bar indicator dropping mid-shift on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tectalk Float uses a voltage-threshold bar indicator, not a fuel gauge chip. Each bar corresponds to a voltage band — typically 4.1V, 3.9V, 3.7V, and a low-battery cutoff near 3.4V. A new cell at storage voltage (~3.75V) will display fewer bars than expected until the first full charge pushes it to 4.2V. One complete charge cycle resets the display to full bars. This is not a capacity defect.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cuts out on PTT press but idles fine\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePMR446 radios draw significantly more current during transmit than during standby — the Tectalk Float's TX current can spike sharply the instant PTT is pressed. If the BMS detects that spike as an overcurrent event, it trips and drops the output before the transmission completes. This usually happens when cell voltage is already low or when contact resistance at the battery terminals is high. Clean the contacts and ensure the battery is fully charged to at least 4.1V before testing again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426286338138,"sku":"BWCS-ABP446TW-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426286370906,"sku":"BWCS-ABP446TW-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426286403674,"sku":"BWCS-ABP446TW-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABP446TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/albrecht-tectalk-float-pmr446-replacement-battery-37v-2000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
