It replaces OEM part numbers HHR-4DPA and HHR-55AAABU. The battery fits directly into the handset battery compartment and connects to the charging contacts that interface with the base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKX-TG6433M, KX-TG1032PK, KX-TG8231B, KX-TG1032S and 123 additional models:\u003c\/strong\u003e\n    These handsets share the same 2.4V dual-cell NiMH pack format, identical connector pitch, and the same base station charging circuit voltage range — one battery spec covers the entire platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charging circuit on KX-TG series hardware. The BMS accepted the charge handshake without error lights, and the pack reached rated voltage within the standard 16-hour slow-charge window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in storage lose electrolyte conditioning — skipping this step leaves the pack 20–30% below rated capacity 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 expected after swapping the battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells shipped in storage state are not at full capacity on arrival — this is normal, not a defect. The cells need three to five full charge-discharge cycles before they reach the 700mAh rating. Each cycle through the base station re-conditions the electrodes and progressively restores capacity. If talk time is still noticeably short after five cycles, measure resting voltage with a multimeter — a healthy charged pack reads between 2.7V and 2.8V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe KX-TG series base station checks pack voltage before starting a charge cycle. A battery that has discharged below roughly 2.0V during storage sits outside the acceptance window, so the base reads it as a fault. Remove the handset, leave it out of the base for 30 seconds, then reseat it firmly so all three charging contacts are flush. If the error persists, check resting pack voltage — anything above 2.0V should trigger the charge cycle on reseating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339911397466,"sku":"BWCS-PTG103CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339911430234,"sku":"BWCS-PTG103CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339911463002,"sku":"BWCS-PTG103CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTG103CL-1.webp?v=1778366944","url":"https:\/\/batteryweb.com\/products\/panasonic-kx-tg6433m-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
