It fits directly into the handset and restores normal operation when the original cell no longer holds a charge. Capacity is rated at 2.52Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBirdy Voice and Concord 3263 fit:\u003c\/strong\u003e\n    Both handsets run on the same 3.6V three-cell Ni-MH pack with an identical footprint — 45.90 × 31.20 × 10.70mm — and share the same connector orientation. One part covers both models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charger and confirmed the BMS accepted charge without triggering an error state. Voltage at full charge read within the expected Ni-MH range before we cleared it for stock.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    Place the handset in the base immediately after fitting and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state won't reach rated capacity unless they complete one slow, uninterrupted charge cycle first.\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 fitting a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT transmitters draw a brief current spike each time the handset sends a radio burst. A Ni-MH cell that hasn't been fully conditioned sags in voltage under that RF load, and the handset's transmit power drops with it. The result looks like a range problem but it's actually a voltage problem. Run three to five full charge-and-use cycles and the cell's internal resistance falls — voltage holds steady under load and range returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or flashing error light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries can sit in storage long enough for cell voltage to fall below the threshold the base station uses to detect a valid pack. When the base sees voltage below roughly 3.0V it won't start a charge cycle — it flags an error instead. Remove the handset, wait 30 seconds, and reseat it firmly so the contacts are fully engaged. If the error persists, a short 15-minute trickle from a standalone Ni-MH charger at 50mA is enough to bring cell voltage above the acceptance threshold and let the base take over.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340016418906,"sku":"BWCS-CPB8011-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340016451674,"sku":"BWCS-CPB8011-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340016484442,"sku":"BWCS-CPB8011-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB8011-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/olympia-birdy-voice-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
