It replaces OEM parts BBTY0457001, BBTY0458001, and BT-446. When your original battery no longer holds a charge, this pack restores the handset to full working order.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDCT6465 \/ DCT7488 handset family:\u003c\/strong\u003e\n    These models share a common 3.6V three-cell NiMH form factor with the same connector orientation and BMS handshake. One pack covers the full range 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 charge and discharge on the DCT6465 handset. The base station accepted the battery without charging errors, and the BMS held stable across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing the battery and leave it for a full 16 hours before use. NiMH cells in cordless phones require this slow initial charge to reach rated capacity — skipping it will result in shorter talk time that does not improve on its own.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after fitting a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DCT6465 transmitter draws a short burst of higher current each time it communicates with the base station. A new or under-conditioned NiMH pack can sag in voltage during that burst, causing the handset to reduce transmit power or drop the connection. This is not a fault with the handset or the base. Run three to five full charge and discharge cycles and the internal resistance of the cells will fall, reducing voltage sag under RF load. Range should stabilise by cycle four.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries can sit in storage long enough for cell voltage to drop below the threshold the Uniden base uses to detect a valid pack. When voltage is too low, the base does not start the charge cycle and the charge indicator stays off. Remove the handset, wait 10 seconds, and reseat it firmly — sometimes one cycle of re-detection is enough. If the light stays off, the pack needs a voltage bump: place the handset in the base, wait 30 minutes, then remove and reseat it. At that point the base should read the pack above its acceptance threshold and begin charging normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340086476890,"sku":"BWCS-BT446CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340086509658,"sku":"BWCS-BT446CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340086542426,"sku":"BWCS-BT446CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BT446CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/uniden-dct6465-replacement-battery-36v-800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
