It replaces the original pack when capacity has dropped or the pack no longer holds a charge. Physical dimensions are 109.74 x 55.63 x 21.86mm — confirm clearance before ordering if your radio uses a fitted belt-clip housing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePA-series platform fit:\u003c\/strong\u003e\n    These four models share the same battery bay geometry, contact pin layout, and 12V Ni-MH voltage rail. The BMS on each radio expects the same charge-acceptance handshake, so one pack covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and transmit load on the PA-series platform. The BMS accepted the new cells without tripping overcurrent, and the voltage rail held steady through sustained PTT presses.\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 pack, wipe the contact pins with a dry cloth, and reseat firmly. Star Hunter charger docks require a clean contact cycle to complete the BMS handshake before charging begins — a single reseating usually clears it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PA-series radio cuts out mid-transmission on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship at storage voltage — typically around 1.1–1.2V per cell rather than the full 1.4V peak. At 12V nominal, ten cells in series means any cell imbalance shows up immediately under PTT load. The radio's BMS reads the voltage sag during transmit and may interrupt output rather than broadcast at reduced quality. Running one or two full charge-discharge cycles before field use brings the cells to working voltage and lets the pack absorb the transmit current spike without tripping the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eStar Hunter PA-series radios use a simple voltage-threshold bar indicator — each bar corresponds to a voltage step, not a fuel-gauge calculation. A new Ni-MH pack at storage voltage will sit below the top threshold and display one bar short of full even when the pack is healthy. This is not a fault. Charge the pack fully — dock light solid green — and the indicator will read correctly at the correct resting voltage of approximately 13.2–13.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426319171674,"sku":"BWCS-SHC130TW-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426319204442,"sku":"BWCS-SHC130TW-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426319237210,"sku":"BWCS-SHC130TW-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHC130TW-1.webp?v=1779930680","url":"https:\/\/batteryweb.com\/products\/star-hunter-pa2099-replacement-battery-12v-1100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
