It fits the P73's battery compartment and connects through the same contact strip as the original. Capacity is 2050mAh (15.17Wh) — matched to the product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP73 platform fit:\u003c\/strong\u003e\n    The P73 runs a 7.4V two-cell Li-ion architecture. This pack matches that voltage rail and uses the same connector footprint, so the BMS handshake with the radio's charge management circuit initiates normally on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through PTT transmit loads and monitored BMS response to the current spike at key-up. The protection circuit held without tripping under sustained transmit bursts at rated draw.\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 P73 charging 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\"\u003eP73 cutting out mid-transmission on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion pack ships at storage voltage — typically 3.7–3.8V per cell, not full charge. When the P73 keys up to transmit, it draws a sharp current spike. If the cell voltage is already near the BMS low-threshold, that spike can trigger an overcurrent cutoff, dropping the transmission. This is a BMS protection event, not a faulty pack. Charge the battery fully before the first use shift and the cutout behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting this pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe P73 uses a voltage-threshold bar indicator — each bar corresponds to a voltage bracket, not a capacity percentage. A pack fresh out of packaging sits at storage voltage, which maps to the second or third bar, not the top. This is correct behaviour. Run one full charge cycle through the dock until the charge LED goes green, and the indicator will step up to reflect the actual charged cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426272378970,"sku":"BWCS-TMR380TW-1","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426272411738,"sku":"BWCS-TMR380TW-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426272444506,"sku":"BWCS-TMR380TW-3","price":67.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMR380TW-1.webp?v=1779930523","url":"https:\/\/batteryweb.com\/products\/harico-p73-replacement-battery-74v-2050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
