It replaces OEM part numbers BL2019 and BL2505. Both radios use the same battery bay, connector pinout, and BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT580H and PT580H Plus fitment:\u003c\/strong\u003e\n    Both models share an identical battery compartment, locking tab geometry, and contact strip layout. The BMS on each radio accepts the same charge-enable signal, so one pack covers both variants without modification.\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 discharge cycles on the PT580H platform. The BMS held the transmit-current spike at PTT press without tripping overcurrent cutoff, and the charger dock progressed to green without fault indication.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip condition on first dock insertion:\u003c\/strong\u003e\n    If the charger shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The PT580H dock requires a clean contact cycle to complete the BMS handshake before it will begin charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePT580H bar indicator showing one fewer bar than expected on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically around 3.7–3.8V per cell, not the 4.2V per cell peak of a full charge. The PT580H uses a voltage-threshold bar indicator, so a fresh pack at storage voltage will display fewer bars than a fully charged one. This is not a capacity defect. Charge the pack fully in the OEM or compatible dock before drawing any conclusions about its state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cuts out mid-transmission on the new BL2019 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eTransmitting draws a sharp current spike — significantly higher than receive or standby draw — and the BMS will cut output if it reads this as an overcurrent event. This can happen if the contact strip has oxidation or debris causing a momentary resistance spike that the BMS interprets as a fault. Clean all six contact points on both the battery and the radio body with a dry cloth, reseat the pack, and confirm the lock tab clicks fully home. If cutout persists, check that the dock has brought the cell to at least 7.2V before field use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426314059866,"sku":"BWCS-HTC807TW-1","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426314092634,"sku":"BWCS-HTC807TW-2","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426314125402,"sku":"BWCS-HTC807TW-3","price":54.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTC807TW-1.webp?v=1779930633","url":"https:\/\/batteryweb.com\/products\/hytera-pt580h-replacement-battery-74v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
