It fits directly into the handset battery compartment and restores talk time and standby duration lost to an aged or failed cell. Dimensions are 35.80 × 33.50 × 7.00mm — confirm against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOpenphone 24 handset fit:\u003c\/strong\u003e\n    The 24 series runs a 2.4V dual-cell Ni-MH configuration. Voltage, physical size, and connector orientation must all match — a mismatched voltage will either fail to charge or trip the base station's charge circuit.\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 a Ni-MH test rig. The cell voltage climbed steadily to the 2.4V nominal rail with no anomalous heat or delta-V collapse at termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge conditioning for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped from storage are partially discharged — a slow initial charge lets the cells reach rated capacity and sets the baseline the base station uses to detect a full charge.\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 not activating on a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries lose charge during storage — a new pack can arrive at 1.8V or lower per cell. Some base stations use a minimum voltage threshold to confirm a valid battery is present before starting the charge cycle. If the pack voltage sits below that threshold, the base reads no battery and the charge indicator stays off. Seat the handset firmly, wait two minutes, and remove and reseat it — this resets the contact detection. If the light still does not activate, check the terminal contacts are clean and making full contact at both ends.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably mid-call after replacing the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Openphone 24 handset increases RF transmit power when moving away from the base station. That draw pulls the Ni-MH pack voltage down sharply, especially in the first few cycles before the cells are conditioned. A voltage sag below roughly 2.0V causes the transmit circuit to throttle back, which the user experiences as range loss or audio breaking up. Run three to five full charge-discharge cycles and the internal resistance of the cells drops — voltage sag under RF load decreases and range returns to normal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339961434202,"sku":"BWCS-AYD3CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339961466970,"sku":"BWCS-AYD3CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339961499738,"sku":"BWCS-AYD3CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AYD3CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/openphone-24-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
