These radios are used in public safety, security, and commercial field operations where communication cannot drop. Capacity figures are taken directly from product data — 18.48Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHP700 and HP780 platform fit:\u003c\/strong\u003e\n    The HP700, HP705, HP780, and HP785 share the same battery bay geometry, connector pinout, and BMS handshake protocol. One pack covers all four models 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 on the HP780 and monitored BMS response through PTT-triggered transmit current spikes. The BMS held without tripping across repeated full-power TX bursts.\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 Hytera 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 HP700 cuts out mid-transmission on a new BP2403\u003c\/h3\u003e\n\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 HP700 fires a high-power TX burst, the BMS sees a sudden current draw against a partially charged cell and triggers an overcurrent cutoff. The radio goes silent mid-transmission even though the battery is brand new. A full charge cycle before the first field shift eliminates this. Once the cells are at 4.2V per cell, the BMS has enough headroom to handle transmit spikes cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting the BP2403\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HP700 series uses a voltage-threshold bar indicator — it reads pack voltage directly and maps it to bars. A new cell at storage voltage sits below the top threshold, so the radio shows three bars instead of four even with a fresh pack. This is not a fault. Charge the battery fully in the dock until the LED goes green, then reinsert — the indicator will read the correct voltage and display the expected bar count.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426277982298,"sku":"BWCS-HPP780TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426278015066,"sku":"BWCS-HPP780TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426278047834,"sku":"BWCS-HPP780TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPP780TW-1.webp?v=1779930584","url":"https:\/\/batteryweb.com\/products\/hytera-hp700-replacement-battery-77v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
