It replaces OEM part KB-32A and fits the standard battery bay on the PT-3200 without modification. Intended for security, hospitality, and industrial radio users who need a fresh pack to maintain shift-length radio coverage.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePT-3200 platform fit:\u003c\/strong\u003e\n    The PT-3200 uses a 7.4V two-cell Li-ion pack with a specific contact pitch and BMS handshake sequence. This replacement matches that voltage rail and connector layout so the charger dock recognises the pack and begins the charge cycle normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through transmit-current draw cycles on the bench. The BMS handled repeated PTT-triggered current spikes without tripping into overcurrent lockout, and the charger dock accepted the pack and progressed through its charge stages correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion into the charger dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first insertion, remove the KB-32A pack, wipe the gold contact strip with a dry cloth, and reseat it firmly. The PT-3200 charger 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 PT-3200 cuts out mid-transmission on a new KB-32A pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNew Li-ion cells ship at storage voltage — typically around 3.7V per cell, giving roughly 7.4V at the pack level. When PTT is pressed, the radio draws a sharp current spike to power the RF output stage. If the pack has not been through a full charge cycle first, that spike can pull the cell voltage below the BMS cutoff threshold momentarily, triggering a protection trip that kills the transmission. Charge the pack fully before first radio use — the dock should show a solid green or full-charge indicator — then reseat it in the radio.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting the KB-32A\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PT-3200 uses voltage-threshold steps to drive the bar indicator — each bar corresponds to a specific cell voltage range. A new pack fresh from storage sits at a resting voltage that places it one threshold below a fully charged pack, so the radio displays one fewer bar even though the pack is not faulty. After one full charge cycle, resting voltage rises to approximately 8.4V, and the indicator will show the correct full-charge bar count. No adjustment to the radio is needed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426300788826,"sku":"BWCS-KRS321TW-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426300821594,"sku":"BWCS-KRS321TW-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426300854362,"sku":"BWCS-KRS321TW-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KRS321TW-1.webp?v=1779930602","url":"https:\/\/batteryweb.com\/products\/kirisun-pt-3200-replacement-battery-74v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
