It replaces the original pack on a like-for-like voltage and form factor basis. The cell stack dimensions — 103.80 x 53.30 x 21.90mm — match the OEM battery bay directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQRZ-1 platform fit:\u003c\/strong\u003e\n    The QRZ-1 runs a 7.4V nominal rail. This pack matches that rail and the physical connector orientation so the radio's power circuit sees no mismatch on boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads typical of handheld radio use. The BMS held the output rail stable under sustained PTT draw and tripped correctly at the low-voltage cutoff threshold — no false lockout on first discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion contact check:\u003c\/strong\u003e\n    If the charger shows a fault LED on first insertion, remove the pack, wipe the contact pads with a dry cloth, and reseat it firmly. The QRZ-1 dock 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 QRZ-1 bar indicator reads low on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells ship at storage voltage — typically 3.6–3.7V per cell, not full charge. The QRZ-1 reads voltage thresholds to display its bar indicator, so a new pack fresh out of packaging will often show one or two bars below full. This is not a capacity fault. Run one full charge cycle through the dock before treating the bar reading as accurate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eQRZ-1 drops TX power mid-shift after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained RF transmission pulls significantly more current than standby or receive modes. If the cell impedance is elevated — common in a new pack that hasn't been cycled — voltage sags under that load and the radio's firmware steps down transmit power to stay within its operating window. This is not a radio fault. Charge the pack fully, run two or three complete discharge-recharge cycles, and the impedance will settle. Check that resting voltage sits at or above 8.0V before the next shift.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426266611802,"sku":"BWCS-BAF130TW-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426266644570,"sku":"BWCS-BAF130TW-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426266677338,"sku":"BWCS-BAF130TW-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BAF130TW-1.webp?v=1779930493","url":"https:\/\/batteryweb.com\/products\/explorer-qrz-1-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
