It replaces OEM part YLLR1865C7800WLS-2 and fits directly into the CP930W housing. When the original cell degrades, call quality and wireless stability drop before the unit shuts down entirely — this swap restores full cordless operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCP930W platform fit:\u003c\/strong\u003e\n    The CP930W runs a single-cell 3.7V Li-ion architecture with a BMS that monitors both audio and DECT wireless draw simultaneously. This replacement matches that voltage rail and connector pinout, so the BMS handshake initialises without error codes on boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under combined audio-plus-DECT load and confirmed the BMS holds the protection threshold steady through sustained conference draws without triggering a false low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-session calibration tip:\u003c\/strong\u003e\n    After installing, run a complete charge cycle before your first meeting. The CP930W maps battery state through normal operation — the indicator may read inaccurately for the first session post-swap until the system completes one full charge-discharge reference pass.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator showing wrong level after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CP930W uses a voltage-threshold model to estimate charge level. A new cell starts at a resting voltage the firmware hasn't mapped yet, so the display can show anything from empty to full on first boot. This isn't a fault with the battery — it's the system working from a stale reference. One complete charge cycle from flat to full resets the threshold table and the indicator reads accurately from that point forward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCP930W not turning on after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement cells shipped from storage often sit below the BMS wake-up threshold — typically under 3.0V — which causes the CP930W to show no response at all when you press power. The BMS locks out to prevent over-discharge damage during transit, not because the cell is faulty. Place the unit on its charging dock and leave it for 20–30 minutes without pressing anything; the dock trickle-charges through the protection circuit until the cell reaches approximately 3.2V, at which point the BMS releases and the unit boots normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339860475994,"sku":"BWCS-YKC930CL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339860508762,"sku":"BWCS-YKC930CL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339860541530,"sku":"BWCS-YKC930CL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YKC930CL-1.webp?v=1778366873","url":"https:\/\/batteryweb.com\/products\/yealink-cp930w-replacement-battery-37v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
