It fits the D5702, D5772, D-5702, and D-5772 models. Swap it in when the original pack no longer holds enough charge to get through a day of calls.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD5702 and D5772 handset compatibility:\u003c\/strong\u003e\n    Both models run the same 3.6V single-cell NiMH pack with an identical connector footprint and cell arrangement. The voltage rail and physical dimensions are shared across the D5702 and D5772 handset chassis, so one battery covers all four model variants listed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on NiMH-rated test equipment. The BMS accepted full charge without cutoff errors, and cell voltage held steady across discharge at normal cordless phone standby and talk draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\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 shipped in partial-charge storage need a slow, uninterrupted initial charge to reach rated 700mAh capacity — a quick top-up will not do it.\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 the first few charges\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries do not ship at full capacity. Fresh cells need three to five full charge-discharge cycles before they reach rated capacity. If talk time feels short after the first charge, that is normal — not a fault with the cell. Run the handset until it signals low battery, then return it to the base for a full charge. By cycle four or five, capacity should be at or close to the rated 700mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new NiMH pack stored at low voltage can fall below the threshold some Ativa base stations use to confirm a valid battery is present. The base reads the incoming voltage, and if it is too low, it stops the charge circuit rather than risk a fault. Place the handset in the base and wait — most units will begin trickle charging within a few minutes once the cell voltage climbs above roughly 3.0V. If the error light clears after 15 to 30 minutes and the charge indicator appears, the battery is accepting current normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340103745626,"sku":"BWCS-CPB9034-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340103778394,"sku":"BWCS-CPB9034-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340103811162,"sku":"BWCS-CPB9034-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB9034-1.webp?v=1778367187","url":"https:\/\/batteryweb.com\/products\/ativa-d5702-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
