It fits the compact 52.30 × 34.00 × 8.50mm battery bay and restores full audio playback capacity. Capacity listed is from product data — 5.55Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClick, Plus, Player, and Touch compatibility:\u003c\/strong\u003e\n    These four models share the same 3.7V single-cell architecture, identical connector pinout, and the same BMS voltage thresholds — that is why one cell fits all four. No rewiring or adapter needed.\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 Click platform. The BMS accepted the cell cleanly, hit the 4.2V charge cutoff correctly, and the low-voltage cutoff triggered at the expected 3.0V floor with no false trips.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge after cell swap:\u003c\/strong\u003e\n    After fitting a new cell, place the player on charge before powering it on. Media players in this class often enter deep-discharge protection after storage, and the device needs a slow trickle charge to clear that state before it will accept a normal charge current.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping after cell swap on the Opus Click\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new Li-Polymer cell, the Opus Click's fuel gauge reads from a calibration table built around the old cell's discharge curve. The new cell has a slightly different internal resistance profile, so the voltage-threshold indicator misreads state of charge early on. This shows up as the percentage jumping — often dropping suddenly from 40% to 5% or climbing unexpectedly. Run two or three full charge-to-cutoff cycles and the gauge recalibrates to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAs a Li-Polymer cell approaches the bottom of its discharge curve, internal resistance rises sharply. The audio amplifier in the Opus Click draws a short burst of current on loud passages, and that current spike causes the cell voltage to sag below the BMS cutoff threshold — even when the indicator still shows charge remaining. The BMS reads that sag as a fault and shuts down the output to protect the cell. If this happens, connect the charger immediately and allow the cell to recover to at least 3.6V before resuming playback.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381325234266,"sku":"BWCS-OPC100SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381325267034,"sku":"BWCS-OPC100SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381325299802,"sku":"BWCS-OPC100SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPC100SL-1.webp?v=1778900029","url":"https:\/\/batteryweb.com\/products\/opus-click-replacement-battery-37v-1500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
