It replaces the original rechargeable cell that sits inside the handset and powers calls and standby operation. Capacity is 400mAh (1.44Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCL306 and CL-306 fitment:\u003c\/strong\u003e\n    Both model codes refer to the same Swisscom Aton handset platform. The battery shares the same voltage rail, physical footprint (48.30 × 33.41 × 6.65mm), and connector orientation, so it seats correctly in the battery compartment 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 passes on a DECT handset platform at 3.6V. The NiMH chemistry accepted a full charge without voltage anomalies, and standby current draw held within the expected range for this class of handset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the CL306:\u003c\/strong\u003e\n    After installing, place the handset in the base cradle for a full 16-hour charge before use. NiMH cells shipped in storage-discharged state need a slow initial charge to reach rated capacity — skipping this step will leave the battery underperforming from day one.\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 original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells typically need three to five full charge and discharge cycles before reaching their rated 400mAh capacity. A new battery used straight from the box will often feel weaker than the original — this is normal chemistry, not a faulty cell. Each time you drain the handset and return it to the base for a full charge, usable capacity increases. By cycle five, the battery should be delivering its full rated performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no-charge or error light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSwisscom Aton base stations check the incoming voltage from the handset battery before initiating a charge cycle. A NiMH cell that has self-discharged in storage may arrive below the threshold the base expects, causing it to show a fault light or refuse to charge. Remove the handset, wait 10 seconds, then reseat it firmly in the cradle. If the error persists, the cell may need a short external boost charge to lift voltage above 3.0V before the base will recognise it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340089098330,"sku":"BWCS-CPT306CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340089131098,"sku":"BWCS-CPT306CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340089163866,"sku":"BWCS-CPT306CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPT306CL_1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/swisscom-aton-cl306-replacement-battery-36v-400mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
