It fits the KX-TC1000, KX-TC1001, KX-TC1005, KX-TC1026, and more than a dozen related models. Direct swap for OEM part numbers P-P305, HHR-P305, and their regional variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-TC1000 series fit:\u003c\/strong\u003e\n    These handsets share the same 2.4V two-cell NiMH pack format, connector pinout, and physical bay dimensions. The BMS in the base station expects a specific charge acceptance profile — this pack matches it.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the KX-TC1000 base charger and confirmed the charge circuit accepted it without error, the voltage rose through both cells evenly, and the handset registered full charge status correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing this battery and leave it for a full 16 hours before first use. NiMH cells at storage voltage need a slow initial charge to reach rated 600mAh capacity — skipping this produces shortened talk time on early cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light stays off after installing a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries sitting in warehouse storage can drop to voltages the base charger treats as an error condition rather than a depleted cell. The KX-TC1000 base uses a delta-V detection circuit that requires at least a minimum threshold voltage to begin the charge cycle. If the charge light stays dark, remove the handset, wait 10 seconds, and reseat it firmly — this forces a fresh detection handshake. If the light still does not activate, measure the pack voltage across the contacts: any reading above 1.8V total means the pack is viable and the base should accept it on a second reseat.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time noticeably shorter than original battery after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells do not reach rated capacity on the first cycle — capacity builds over the first three to five full charge and discharge cycles. If talk time feels short immediately after installation, the cells have not yet been conditioned. Run the handset until the low-battery tone sounds, then return it to the base for a full charge, and repeat this three times. By cycle four, the pack should be delivering close to its rated 600mAh and talk time will reflect that.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340097224794,"sku":"BWCS-P305CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340097257562,"sku":"BWCS-P305CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340097290330,"sku":"BWCS-P305CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P305CL-1.webp?v=1778367187","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-tc1000-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
