It fits the FT-4703, FTC-5203, HH2500, MA18U, and eight additional Standard portables that share the FNB-2 form factor. Voltage and connector match OEM spec — no modifications needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFT-4703 \/ FTC-5203 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, contact layout, and 10.8V voltage rail. One pack covers the full FNB-2 compatible group without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on a Standard-compatible dock. The BMS responded correctly to charge termination at peak voltage delta — no false cutoffs, no thermal flags.\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 Standard platform 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\"\u003eWhy the FT-4703 cuts out mid-transmission on a new FNB-2 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at partial charge — typically 30–50% of rated capacity. When PTT is pressed, transmit current spikes sharply. A cell at storage voltage cannot sustain that draw, and the radio's undervoltage protection trips the output stage. This is a cell state issue, not a BMS fault. Run one full charge cycle on the dock before putting the radio into service and the cutout behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator shows one fewer bar than expected after fitting a new FNB-2\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStandard portables read battery state through voltage-threshold bar indicators — each bar maps to a voltage band. A new Ni-MH pack at storage voltage sits below the top threshold, so the display shows one bar short even on a fresh cell. This is not a capacity defect. Charge the pack fully on a Standard-compatible dock and the indicator will step up to the correct bar count once resting voltage stabilises above 11.5V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426322055258,"sku":"BWCS-UPX500TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426322088026,"sku":"BWCS-UPX500TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426322120794,"sku":"BWCS-UPX500TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UPX500TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/standard-ft-4703-replacement-battery-108v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
