It also fits the DCP 12-300, DCP 40-330 ISDN, and DCP300 series handsets. It matches the original T306 specification and fits the same battery compartment without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDECT 330 series compatibility:\u003c\/strong\u003e\n    These handsets share the same 3.6V single-cell Ni-MH architecture and T306 form factor. The battery connector, cell count, and compartment dimensions are identical across the DCP 12-300, DCP 40-330 ISDN, and DCP300 variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a DECT handset base station and confirmed the BMS accepted the charge without error. Voltage stabilised at 4.2V at full charge and the handset registered a full battery indicator after a slow overnight charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells in cordless phones ship partially discharged and need a slow initial charge cycle to reach rated capacity — skipping this step can permanently reduce how much charge the pack holds.\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 T306 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity on the first charge cycle. The DECT Phone 330 charges at a low trickle rate, which means the first few cycles will feel short compared to the original battery at its best. Capacity builds across three to five full charge-discharge cycles. Run the handset until the low battery tone sounds, then return it to the base for a full 16-hour charge — repeat this three times and rated capacity will stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement Ni-MH packs often sit in storage for months and arrive at a resting voltage below 3.0V. Some DECT base stations interpret this as a fault and refuse to initiate a charge cycle. If the charge indicator stays off or shows an error, remove the handset, wait 30 seconds, and reseat it firmly — this resets the base station's charge controller. If the error persists, check that the handset contacts and base cradle contacts are clean and making solid contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340088934490,"sku":"BWCS-CPT306CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340088967258,"sku":"BWCS-CPT306CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340089000026,"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\/sagem-dect-phone-330-replacement-battery-36v-400mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
