It matches the voltage and form factor of the original CPH-464D pack. If your handset no longer holds a charge, this swap restores full operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPH-464D compatibility:\u003c\/strong\u003e\n    Cordless handsets using this part number share a 3.6V three-cell Ni-MH configuration with a common connector orientation and cell spacing. The BMS on these bases expects that voltage window to trigger a charge cycle — deviation causes charge refusal.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full charge-discharge sequence on a CPH-464D-compatible handset. The base station accepted the charge cycle immediately, the BMS completed top-off without interruption, and cell voltage held steady at 3.6V through discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge requirement for Ni-MH handsets:\u003c\/strong\u003e\n    Place the handset in the base cradle for a full 16-hour charge before first use. Ni-MH cells arrive partially discharged from storage — a slow initial charge lets all three cells balance and reach rated 700mAh capacity. Skipping this step leaves capacity on the table for the first several cycles.\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 the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity straight out of the box. Storage causes partial self-discharge, and the chemistry needs three to five full charge-discharge cycles before the cells hit their 700mAh ceiling. Each cycle improves capacity noticeably. Run the handset until the low-battery indicator trips, return it to the base for a full charge, and repeat — capacity builds with each pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no-charge or error light after installing the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCordless bases check incoming voltage before starting a charge cycle. A Ni-MH pack that has sat in storage can drop below the threshold the base uses to confirm a valid battery is present. Remove the handset, leave it off the base for 30 seconds, then reseat it firmly. If the error light persists, check that the battery contacts on the handset and base are clean and making full contact — oxidised contacts at 3.6V are enough to fail the detection check.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339870634074,"sku":"BWCS-MTD716CL-1","price":205.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339870666842,"sku":"BWCS-MTD716CL-2","price":245.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339870699610,"sku":"BWCS-MTD716CL-3","price":275.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTD716CL-1.webp?v=1778366872","url":"https:\/\/batteryweb.com\/products\/empire-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
