It matches OEM part numbers CPA141, CPA2800, and ASCAK141. Capacity figures are sourced from product data — 1200mAh at 9Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFuG11B and SE140 platform fit:\u003c\/strong\u003e\n    The FuG11B, SE110, and SE140 share the same battery bay dimensions, connector pinout, and 7.5V supply rail. One pack covers all three models without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through a full charge cycle and confirmed the BMS accepted charge without fault flagging. Transmit-load current draw was stable across multiple PTT press cycles, with no mid-cycle cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip condition on first dock insertion:\u003c\/strong\u003e\n    If the charger shows a fault indication on first use, remove the pack, wipe the battery contact strip with a dry lint-free cloth, and reseat it firmly. The Ascom dock requires a clean contact cycle to handshake with the new pack's BMS 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 FuG11B BMS trips on hard PTT press with a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePressing PTT on a two-way radio draws a short transmit-current spike that can be two to three times the steady-state draw. A new Ni-MH cell sitting at storage voltage — typically around 7.2V — has slightly higher internal impedance than a conditioned cell. If that impedance causes the voltage to dip below the BMS cutoff threshold during the spike, the pack shuts off. The fix is to run one or two full charge cycles before heavy use, which lowers impedance and brings resting voltage up to the 7.5V nominal rail.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator reads one bar low on a fully charged new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe FuG11B uses a simple voltage-threshold indicator — each bar corresponds to a voltage band, not a calculated state of charge. A new Ni-MH pack often ships at 70–80% storage charge, which sits in the second-to-top voltage band and displays one fewer bar than a fully charged cell. This is not a capacity fault. Dock the pack for a complete charge cycle until the charger shows green, then recheck the indicator — it should read full.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426291286106,"sku":"BWCS-ASF140TW-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426291318874,"sku":"BWCS-ASF140TW-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426291351642,"sku":"BWCS-ASF140TW-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ASF140TW-1.webp?v=1779930583","url":"https:\/\/batteryweb.com\/products\/ascom-fug11b-replacement-battery-75v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
