It replaces part number AHB102050PJT directly. Fits the Ti100 only — check your OEM part number before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi100 cell fit:\u003c\/strong\u003e\n    The Ti100 runs a single-cell Li-Polymer pack at 3.7V nominal. The BMS in the headset monitors cell voltage and current draw across both the audio codec and the Bluetooth radio simultaneously — the replacement cell must match the original voltage profile or the BMS will cut power early.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through combined Bluetooth radio and audio load. The BMS accepted the new pack without error, held voltage above 3.4V under sustained draw, and completed a full charge cycle from the base station without a fault flag.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBase station first charge:\u003c\/strong\u003e\n    Seat the headset in the base station immediately after fitting and leave it for a complete charge cycle before use. The Ti100's talk-time counter reads from the base station's charge log — if the base hasn't completed one full cycle with the new cell, the displayed talk-time estimate will be inaccurate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Ti100 cuts out mid-call even with a new battery fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ti100 pulls current from two sources at once — the audio driver and the Bluetooth radio. During an active call, this combined draw briefly spikes above what the BMS expects from a cell at storage voltage. If the new cell hasn't been through a full charge cycle, resting voltage sits around 3.6–3.7V but the BMS still trips on the spike. One complete charge-discharge cycle brings the cell up to full capacity and stabilises the BMS response to those draw spikes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but headset dies after a few minutes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell arrives at storage voltage — typically 3.75–3.80V — and the base station interprets that as a near-full charge, terminating the cycle early. The cell never reaches true full capacity. The fix is to discharge the headset fully with a call or audio playback, then return it to the base for a complete uninterrupted charge. After one proper full cycle, the base station's charge termination logic resets to the correct cutoff point for the new cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428115775578,"sku":"BWCS-RPT100SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428115808346,"sku":"BWCS-RPT100SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428115841114,"sku":"BWCS-RPT100SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RPT100SL-1.webp?v=1779934164","url":"https:\/\/batteryweb.com\/products\/rapoo-ti100-replacement-battery-37v-900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
