It runs at 3.6V with a 700mAh capacity. The physical dimensions are 44.50 × 31.00 × 11.00mm — same footprint as the original Cobra battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePR145, PR150, and PR155 GMRS compatibility:\u003c\/strong\u003e\n    These three models share the same 3.6V Ni-MH chemistry, connector pinout, and battery bay dimensions. One GA-BP3 pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and PTT-burst discharge sequences on a PR150. The BMS handled transmit current spikes without tripping, and the voltage held steady across repeated short-burst transmissions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the Cobra dock:\u003c\/strong\u003e\n    If the charger shows a fault indicator on first insert, remove the pack and wipe the contact pads with a dry cloth before reseating. The Cobra dock runs a contact check before accepting the new pack — a residue-covered pad can block that handshake and prevent charging from starting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PR145 cuts out mid-transmission on a new GA-BP3\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell ships at storage voltage — typically around 1.1V per cell, not the 1.2V nominal it reaches after conditioning. On a 3-cell pack like this one, that means the pack may sit just above 3.3V when you first insert it. When PTT is pressed, transmit draw spikes sharply, and that marginal voltage dips further, triggering the radio's low-voltage cutout. The fix is to run one full charge cycle before using the radio. After the first full charge, the pack stabilises at its rated 3.6V and handles transmit bursts without dropout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator reading one bar low after fitting a new GA-BP3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PR145 series uses a simple voltage-threshold bar display — each bar maps to a voltage band, not a calculated capacity. A new pack at storage voltage reads lower than a fully charged one, so the indicator may show one fewer bar than expected even though the pack is not faulty. Charge the pack fully before reading the indicator. Once the pack reaches full charge voltage, the bar display will step up to reflect the actual state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426339946586,"sku":"BWCS-CPR150TW-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426339979354,"sku":"BWCS-CPR150TW-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426340012122,"sku":"BWCS-CPR150TW-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPR150TW-1.webp?v=1779930719","url":"https:\/\/batteryweb.com\/products\/cobra-pr145-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
