It restores audio playback and wireless connectivity after the original cell has degraded through repeated charge cycles. Capacity is 2.59Wh, matching the stock specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRPT-01 battery fit:\u003c\/strong\u003e\n    The RPT-01 uses a compact Li-Polymer cell at 42.00 × 29.80 × 6.10mm. That specific footprint and the onboard BMS handshake determine which cells will seat and communicate correctly — the AHB603040 part number confirms the match.\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 RPT-01 platform. The BMS accepted the new pack without error flags, and the protection circuit responded correctly to both low-voltage cutoff and charge termination signals.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge protocol for the RPT-01:\u003c\/strong\u003e\n    Place the headset in its charging cradle and run a full, uninterrupted charge before first use. The RPT-01's firmware logs the new cell during that first complete cycle — skip it and the talk-time estimate displayed will be inaccurate until the cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the RPT-01 cuts out mid-audio on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe RPT-01 pulls simultaneous current for both audio processing and its wireless radio. Under that combined draw, a cell that hasn't completed its first full cycle can sag below the BMS cutoff threshold briefly, dropping the connection. This isn't a faulty cell — it's the protection circuit responding to a momentary voltage dip in an undercharged pack. Running one complete charge cycle before use stabilises the cell voltage and prevents that sag under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than rated on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-Polymer cell doesn't deliver full capacity on day one. Internal resistance is slightly higher out of storage, and the electrolyte needs several charge-discharge cycles to fully condition. On the RPT-01, rated talk time typically isn't reached until cycle three to five. Each full charge-discharge pass reduces internal resistance incrementally — by cycle five, measured capacity should be at or close to the rated 700mAh.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428098408538,"sku":"BWCS-APT001SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428098441306,"sku":"BWCS-APT001SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428098474074,"sku":"BWCS-APT001SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-APT001SL-1.webp?v=1779934060","url":"https:\/\/batteryweb.com\/products\/adidas-rpt-01-replacement-battery-37v-700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
