It replaces the original rechargeable cell that powers the handset during wireless calls and standby. Dimensions are 35.80 × 33.50 × 7.00mm — confirm these match your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntegral D3, Openphone 28, and OpenPhone 24 compatibility:\u003c\/strong\u003e\n    These three handsets share the same battery bay dimensions and 2.4V NiMH cell format, which is why one replacement cell covers all three models without modification.\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 a NiMH test rig. Capacity settled at rated output by cycle three, and voltage held steady through the discharge curve without early cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cordless phone batteries reach rated capacity through a slow initial charge — a quick top-up will not fully condition the cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after a battery swap on the Integral D3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Integral D3 handset adjusts its RF transmit power based on available voltage from the battery. A new NiMH cell straight from storage sits at a depressed open-circuit voltage — sometimes below 2.2V — which causes the handset to throttle transmit power and shorten usable range. This is not a fault with the replacement cell. After two or three full charge cycles, the NiMH pack recovers to its nominal 2.4V and the handset transmits at full power again.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome DeTeWe base stations sample the battery voltage on contact and withhold charging current if the reading falls below their acceptance threshold. A new NiMH cell that has self-discharged in storage can read low enough to trigger this behaviour. Remove the handset, wait 10 seconds, and reseat it firmly — the base will re-sample and usually begin charging. If the error persists, check that the handset contacts are clean and that the cell is making solid contact with the battery terminals inside the handset.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339992989786,"sku":"BWCS-AYD3CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339993022554,"sku":"BWCS-AYD3CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339993055322,"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\/detewe-tenovis-integral-d3-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
