It fits the FT-25R, FT-65R, and FTA-250L handheld transceivers — three compact VHF radios that share the same battery form factor and connector. Dimensions are 88.56 × 51.40 × 15.84mm, matching the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFT-25R \/ FT-65R \/ FTA-250L platform fit:\u003c\/strong\u003e\n    All three radios run the same 7.4V battery rail and use an identical mechanical housing with the same contact arrangement. One battery services all three models 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 multiple PTT transmit bursts on the FT-25R. The BMS held steady under the current spike at transmit, and the protection circuit tripped correctly at the low-voltage threshold without nuisance cutoffs at mid-charge levels.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the FTA-250L dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat it firmly. The FTA-250L dock requires a clean contact cycle to complete the BMS handshake before charging will begin.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the FT-25R cuts out mid-transmission on a freshly inserted SBR-25L\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew cells ship at storage voltage — typically around 3.7V per cell, or 7.4V combined — not at full charge. When you key up on a new pack at storage voltage, the transmit current spike pulls the cell voltage down sharply. The BMS reads that dip as a low-voltage fault and cuts the output before the transmission completes. This is not a faulty pack — it is the protection circuit doing its job on an undercharged cell. Charge the pack fully before first transmit use and the cutoff will not trigger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe FT-25R and FT-65R use a simple voltage-threshold bar display — each bar maps to a voltage window, not a capacity percentage. A new cell with slightly higher internal impedance than the original will show a marginally lower resting voltage immediately after the charger goes green, which maps to one bar fewer on the display. Run two full charge-discharge cycles and the resting voltage will stabilise. After conditioning, the bar reading should align with the pack at or above 8.0V resting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426307375194,"sku":"BWCS-FNT250TW-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426307407962,"sku":"BWCS-FNT250TW-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426307440730,"sku":"BWCS-FNT250TW-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNT250TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/yaesu-ft-25r-replacement-battery-74v-1950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
