It replaces the OEM BT-1009 pack and fits the DK-T2404-DECT variant as well. Install it when the original battery no longer holds charge through a full call or drains overnight in the base.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDKT2404-DECT and DK-T2404-DECT compatibility:\u003c\/strong\u003e\n    Both model designations use the same handset chassis, connector orientation, and 2.4V two-cell Ni-MH configuration. The BT-1009 pack fits either 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 DKT2404-DECT base station and confirmed the BMS accepts the Ni-MH charge curve without triggering an error light. Voltage held steady across standby and active RF transmit draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the DKT2404-DECT base:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a full 16-hour charge before first use. Ni-MH cells in cordless phone packs require a slow initial charge to reach rated capacity — skipping this step consistently produces short talk time in the first few cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the DKT2404-DECT after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells fresh from storage sit at a suppressed resting voltage, sometimes as low as 2.1V across the two-cell pack. The DKT2404-DECT handset draws a surge of current during DECT RF transmit bursts, and a low-voltage pack sags further under that load. When the pack voltage dips below the handset's RF threshold, transmit power drops and range shrinks noticeably. Two to three full charge-discharge conditioning cycles through the base station bring the cells to rated voltage and resolve the sag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge indicator after fitting the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DKT2404-DECT base expects the incoming pack voltage to clear a minimum acceptance threshold before it activates the charge circuit. A Ni-MH pack that has self-discharged in storage can read below that threshold, so the base either shows no charge light or displays an error. Remove the handset, leave it off the base for 30 seconds, then reseat it firmly — this resets the charge negotiation cycle. If the base still does not respond, check that the handset contacts are clean and the pack is sitting at or above 2.0V with a multimeter before reseating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340103090266,"sku":"BWCS-P105CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340103123034,"sku":"BWCS-P105CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340103155802,"sku":"BWCS-P105CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P105CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/toshiba-dkt2404-dect-replacement-battery-24v-850mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
