It fits the multi-cell compartment shared across these models and connects to the same charging contacts used by the base station. Capacity is 600mAh (1.44Wh), matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP464 \/ CP702 platform fit:\u003c\/strong\u003e\n    These models share the same 2.4V dual-cell NiMH pack format, charging circuit, and contact layout. One replacement covers the full platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran charge and discharge cycles on this pack through a base station charging circuit. The BMS accepted charge normally, voltage settled at the expected 2.4V endpoint, and the handset powered on cleanly at each stage.\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 cordless phones need that slow initial charge to reach rated capacity — skipping it leaves the pack at roughly 60–70% of its rated output 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\"\u003eBase station showing no charge or error light after installing a new NiMH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly shipped NiMH battery often sits at 1.0–1.1V per cell after storage — well below the threshold the Cobra base station expects before initiating a charge cycle. The base reads this as a fault rather than a depleted pack. To recover it, place the handset in the base and wait — most Cobra chargers will trickle-charge a low-voltage pack for 30 to 60 seconds before switching to normal charge mode. If the error persists beyond that window, remove the handset, wait 10 seconds, and reseat it to force a fresh detection cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells need three to five full charge-discharge cycles before the chemical structure stabilises and the pack reaches rated capacity. On the first cycle you may see noticeably shorter talk time — this is normal cell conditioning, not a fault with the pack. Run the handset until it signals low battery, return it to the base for a full charge, and repeat. By cycle four or five, output should be consistent with the 600mAh rating.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340094701658,"sku":"BWCS-P305CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340094734426,"sku":"BWCS-P305CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340094767194,"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\/cobra-cp464-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
