It restores charging capacity when the original cell can no longer hold a usable charge. The CT901HS is a DECT wireless headset used in office environments for hands-free calling.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCT901HS fit:\u003c\/strong\u003e\n    The CT901HS headset uses a compact 3-cell Ni-MH pack at 3.6V nominal. This battery matches that voltage rail and physical footprint, so the headset seats correctly in the base charging cradle without connector stress.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the bench. The cells accepted a full charge without thermal runaway and held stable voltage under the low RF transmit draw typical of DECT headsets.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on NiMH cordless headsets:\u003c\/strong\u003e\n    After installing, place the CT901HS in its base cradle for a full 16-hour charge before first use. Ni-MH cells shipped in storage state need a slow initial charge to reach rated 700mAh capacity — a fast first cycle will leave the pack underformed for the first several uses.\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 no charge light after fitting a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries lose voltage during storage and can arrive below the threshold the CT901HS base uses to confirm a valid pack is seated. If the base sees a resting voltage too low, it may not initiate the charge cycle at all. Place the headset firmly in the cradle and leave it undisturbed — some bases need up to 30 minutes before the charge indicator activates on a deeply discharged cell. If the light still does not appear, check that the headset connector pins are clean and making full contact with the cradle contacts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Ni-MH cell does not deliver full rated capacity on the first cycle — this is normal cell chemistry, not a fault. Capacity builds over the first three to five full charge-discharge cycles as the crystalline structure in the cells reforms. Run the headset to low charge, return it to the base for a full 16-hour charge, and repeat. By cycle five, the pack should be delivering close to its rated 700mAh and noticeably longer talk time than cycle one.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340080283738,"sku":"BWCS-P501CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340080316506,"sku":"BWCS-P501CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340080349274,"sku":"BWCS-P501CL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/plantronics-ct901hs-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
