It replaces OEM part numbers BT185 and AM468V. Fit this battery when your handset stops holding a charge or drops off calls within minutes of leaving the base.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCT301 and DX series compatibility:\u003c\/strong\u003e\n    These handsets share the same 3.6V single-cell NiMH pack format, identical connector pinout, and the same base station charge circuit. One battery services the full lineup 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 the CT301 base station and confirmed the BMS accepted charge from cold storage, reached full voltage without triggering the base's overcharge cutoff, and held standby draw within spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it there for a full 16 hours before first use. NiMH cells shipped from storage are partially discharged and need a slow initial charge to reach rated capacity — a short first charge leaves you with noticeably less talk time from day one.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells don't deliver rated capacity on the first cycle — they typically need three to five full charge-discharge cycles to condition the cell chemistry. If your CT301 talk time feels short after the first day, that's expected. Run the handset through full discharge and 16-hour base charges for three to five cycles. By cycle four, capacity should settle at or near the rated 600mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eUniden base stations check for a minimum acceptance voltage before starting the charge cycle. A new battery sitting in a warehouse can drop low enough that the base reads it as a fault and refuses to charge. If the charge light stays off, remove the battery, let it sit at room temperature for 30 minutes, then reinstall and reseat firmly in the base. If the light still won't activate, confirm the handset contacts and base cradle contacts are clean — 3.6V on the meter at the battery terminals means the pack itself is not the fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340108562522,"sku":"BWCS-CPB8013-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340108595290,"sku":"BWCS-CPB8013-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340108628058,"sku":"BWCS-CPB8013-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB8013-1.webp?v=1778367187","url":"https:\/\/batteryweb.com\/products\/uniden-ct301-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
