It replaces the original cell when the handset stops holding charge or talk time drops noticeably. Dimensions are 30.00 × 32.00 × 10.50mm — confirm these match your existing cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAMARYS 2200SF handset fit:\u003c\/strong\u003e\n    The AMARYS 2200SF uses a compact single-cell Ni-MH pack at 3.6V. This battery matches that voltage rail and physical footprint, so the handset's charge circuit sees the correct input without modification.\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 the bench. The Ni-MH chemistry reached rated capacity by cycle three — output voltage held steady across the discharge curve without unexpected sag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the AMARYS 2200SF:\u003c\/strong\u003e\n    After fitting, seat the handset in the base station and leave it for a full 16 hours before use. Ni-MH cells in cordless phones need this slow initial charge to reach rated capacity — skipping it locks in a lower usable ceiling from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error after fitting a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH cell that has sat in storage will have a lower resting voltage than a fully charged pack. Some DECT base stations read this low voltage as a fault and refuse to start a charge cycle. The fix is to leave the handset seated in the base for at least 30 minutes without removing it — most base circuits will detect the cell and begin a trickle charge once the initial handshake passes. If the error light stays on after 30 minutes, remove the handset, wait 10 seconds, and re-seat it to trigger a fresh detection cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAMARYS 2200SF losing range after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eReduced range after a battery replacement usually points to voltage sag under RF transmit load. When a Ni-MH cell is not yet conditioned, its internal resistance is higher — voltage drops the moment the radio module draws current to transmit, and the handset pulls back signal strength to compensate. This is not a faulty battery. Run three full charge and discharge cycles through normal use and the internal resistance drops as the chemistry settles. Range typically returns to normal by cycle four.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340011733082,"sku":"BWCS-SEC31CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340011765850,"sku":"BWCS-SEC31CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340011798618,"sku":"BWCS-SEC31CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SEC31CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/telecom-amarys-2200sf-replacement-battery-36v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
