It fits the CP161AUS, CP250AUS, CP260AUS, and CP261AUS models. The cell pack matches the original voltage and physical dimensions, so it seats and charges in the handset without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP161AUS \/ CP250AUS \/ CP260AUS \/ CP261AUS fit:\u003c\/strong\u003e\n    These handsets share the same 3.6V single-cell NiMH pack format, connector orientation, and charge circuit. One pack covers all four models because the base station delivers the same trickle-charge current to each handset.\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 CP-series base station. The BMS accepted charge from cycle one, and cell voltage held within spec across five full cycles without thermal trip or charge rejection.\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 this battery and leave it for a full 16 hours before first use. NiMH cells in cordless phones are shipped partially discharged — a slow initial charge lets the cells reach rated capacity and sets the baseline the handset uses to track charge state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light on a new NiMH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAkai base stations use a voltage threshold to detect whether a handset is ready to accept charge. A fresh replacement NiMH pack can sit in storage long enough for its resting voltage to drop below that threshold — typically under 3.0V. When the base sees that low voltage, it interprets the pack as a fault rather than a flat battery and withholds current. Removing the handset, waiting 30 seconds, and reseating it triggers a fresh detection cycle. If the base still shows an error, leave the handset seated for 20–30 minutes — most Akai charger circuits will eventually push a recovery pulse once the pack voltage climbs above 3.2V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is normal for the first three to five cycles on a fresh NiMH pack. New cells have not yet reached full crystalline alignment, so initial capacity runs short of the rated 600mAh. Each full charge-and-discharge cycle builds usable capacity incrementally. Run three complete cycles — full 16-hour charge followed by use until the low-battery alert sounds — and talk time will stabilise at rated capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339960811610,"sku":"BWCS-P403CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339960844378,"sku":"BWCS-P403CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339960877146,"sku":"BWCS-P403CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P403CL-1.webp?v=1778367001","url":"https:\/\/batteryweb.com\/products\/akai-cp161aus-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
