It replaces OEM part BP4008 and fits the same physical bay with the same gold contact strip layout. Capacity figure is taken directly from product data — 15.2Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePNC360 and PNC360S compatibility:\u003c\/strong\u003e\n    Both models run on the same 3.8V power rail and use the same BP4008 form factor. The BMS handshake protocol is identical across both variants, so one battery covers the full PNC360 platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated PTT transmit loads. The BMS held the voltage rail stable through repeated high-current spikes and did not trigger overcurrent cutoff during sustained transmission bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the PNC360 dock:\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 PNC360 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\"\u003eWhy the PNC360 cuts out mid-transmission on a new BP4008\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer pack ships at storage voltage — typically around 3.6V — not at full charge. When PTT is pressed, transmit current spikes sharply, and a cell at storage voltage can sag below the BMS cutoff threshold in that instant. The radio interprets this as a low-battery shutdown, not a hardware fault. The fix is to run a full charge cycle before first use in the field. Once the cell is at 4.2V, the voltage headroom is sufficient to absorb the transmit spike without triggering cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting the BP4008\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PNC360 uses a simple voltage-threshold bar indicator — each bar corresponds to a voltage band, not a calculated state of charge. A new pack at storage voltage sits in a lower band and displays one or two bars even though the cell is not depleted. This is not a faulty battery. Charge the pack fully in the dock until the LED goes solid green, then insert it into the radio — the indicator will read correctly at the higher resting voltage, typically above 4.1V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426290729050,"sku":"BWCS-HPN360TW-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426290761818,"sku":"BWCS-HPN360TW-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426290794586,"sku":"BWCS-HPN360TW-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HPN360TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/hytera-pnc360-replacement-battery-38v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
