It powers the image sensor, LCD display, and onboard processing circuitry. Swap it in when the original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompactline 83 fit:\u003c\/strong\u003e\n    The Compactline 83 uses a slim single-cell Li-ion pack at 3.7V nominal. This cell matches the original voltage rail and physical dimensions (53.00 × 34.00 × 4.80mm), so the battery door closes and the contacts seat correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the bench. The protection circuit responded correctly to over-discharge and over-current conditions, and the camera's charge indicator cleared on a standard cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStorage before a shoot:\u003c\/strong\u003e\n    If the camera has been sitting unused for several months, charge the battery fully before heading out — compact camera charge controllers do not always flag a partially depleted cell accurately after long idle periods.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Compactline 83 shuts off mid-use with charge still showing\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe camera's fuel gauge reads the cell's open-circuit voltage, not actual remaining capacity. A degraded or new uncalibrated cell can show 40% charge, then drop below the 3.0V cutoff threshold the moment the LCD backlight and image processor load the circuit simultaneously. This is a voltage cliff — the cell cannot sustain current under combined load even though resting voltage appears fine. One full discharge-to-cutoff and full recharge cycle recalibrates the gauge against the new cell's actual discharge curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera won't power on after the replacement battery was left uncharged in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells discharged below approximately 2.5V trigger the protection circuit's lockout state — the BMS disconnects the cell to prevent damage, and the camera sees zero voltage at the contacts. A standard charger may not recover a locked-out cell because it waits for a minimum voltage signal before starting charge current. Connect the battery to a charger that supports a low-voltage recovery or trickle pre-charge mode. Once the cell recovers to around 3.0V, normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409494343770,"sku":"BWCS-NK4CXL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409494376538,"sku":"BWCS-NK4CXL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409494409306,"sku":"BWCS-NK4CXL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK4CXL-1.webp?v=1778213576","url":"https:\/\/batteryweb.com\/products\/rollei-compactline-83-replacement-battery-37v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
