It replaces OEM part number PSPT3HRAAU41 and fits the KX-TD7894 and KX-TDTD7895 handsets. The original battery degrades over time — this pack restores full cordless function to the handset.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-TD7894 and KX-TDTD7895 handsets:\u003c\/strong\u003e\n    Both models share the same 3.6V three-cell NiMH pack format, the same connector orientation, and the same base station charging circuit. One battery fits both handsets 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 KX-TD7894 base station charging circuit. The BMS accepted the charge correctly, voltage reached 4.2V at full charge, and the handset reported full charge status on the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base and leave it for a full 16 hours before first use. NiMH packs shipped in storage state need a slow, full charge cycle to reach rated 1500mAh capacity — skipping this step will result in noticeably shorter 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\"\u003eRange dropping on the KX-TD7894 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe KX-TD7894 transmit circuit draws a surge of current each time the handset sends a DECT radio burst. A NiMH pack that has not been properly conditioned will sag in voltage under that RF load. When voltage sags too far, the handset reduces transmit power to protect the circuit. The fix is to complete three to five full charge-discharge cycles so the cells reach their rated capacity and internal resistance drops to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries sitting in warehouse storage can drop to 3.0V or below. The KX-TD7894 base station charging circuit expects the pack to be above a minimum threshold voltage before it starts the charge cycle — a deeply discharged pack can fall outside that window and the base shows no charge activity. Leave the handset seated in the base for at least 30 minutes; some base stations will trickle-charge below threshold before switching to full charge mode. If the charge light still does not appear after 30 minutes, remove the battery, check the terminal voltage with a multimeter, and confirm it reads at least 3.0V before reseating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339967987802,"sku":"BWCS-CPB400JL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339968020570,"sku":"BWCS-CPB400JL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339968053338,"sku":"BWCS-CPB400JL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB400JL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-td7894-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
