It matches the OEM part number SL-422943 and fits the slim battery compartment at 43 × 28 × 4mm. Replace it when the original no longer holds a charge or the handset dies faster than it used to.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eScenos and Scenos A compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V Li-ion cell format, connector orientation, and BMS handshake with the base station charging circuit — one battery covers both handset variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a DECT handset test rig. The BMS held the cutoff voltage correctly and the base station recognised the pack without throwing a charge error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for this handset:\u003c\/strong\u003e\n    Place the handset in the base immediately after fitting the new battery and leave it for a full charge cycle before use. Li-ion cells shipped at partial state-of-charge need one complete cycle to let the BMS calibrate the capacity gauge accurately.\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 fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed Li-ion cell rarely delivers full rated capacity on the first cycle. The BMS starts with an uncalibrated state-of-charge estimate, which can cause the handset to report low battery earlier than it should. Run two to three full charge-and-discharge cycles and the gauge will align with the actual 500mAh capacity. If talk time remains short after three cycles, check that the handset sits fully seated in the base — a loose contact delivers a partial charge each time.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery cuts all power to the handset, and some DECT phones store pairing data in volatile memory backed by the cell. When power drops to zero, that registration is lost. Re-register the handset to the base through the base station menu — typically a long-press on the paging button on the base unit. The process takes under two minutes and does not require resetting any other handsets already paired to the same base.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340055937114,"sku":"BWCS-P28115CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340055969882,"sku":"BWCS-P28115CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340056002650,"sku":"BWCS-P28115CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P28115CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/grundig-scenos-replacement-battery-37v-500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
