It sits in the same physical envelope as the original cell — 39.50 × 35.40 × 5.60mm — and connects to the same contact plate inside the battery bay. Swap it in when the original cell no longer holds charge through a full shoot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCL200 and DA-101 shared battery platform:\u003c\/strong\u003e\n    These models share the same voltage rail and battery bay dimensions, which is why one cell fits all of them. The BMS inside each body expects the same 3.7V nominal input and uses the same contact arrangement to read cell state.\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 bench, confirming the BMS handshake completes cleanly and the protection circuit trips correctly at the low-voltage cutoff threshold before the cell can be damaged by overdischarge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the CL200:\u003c\/strong\u003e\n    Run one full charge through the camera body or OEM charger before your first shoot. The Compactline 200's battery-level indicator maps voltage thresholds from a known baseline — skipping this step often produces erratic percentage readings on the display.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDead battery indicator showing on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Compactline 200 uses a stepped voltage-threshold system to estimate remaining charge. A new cell's discharge curve doesn't always align with the thresholds the camera was calibrated against, so the body can misread a cell that still has usable voltage and throw a low-battery warning early. This isn't a faulty cell — it's a calibration mismatch. Running one full charge-discharge cycle through the camera body resets the reference point the BMS uses and brings the indicator back in line.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the percentage display skips — say, from 60% straight to 20% — the camera's voltage-to-percentage mapping is reading the new cell's discharge curve incorrectly. Compact camera BMS firmware maps battery level against specific voltage steps tuned to the original cell chemistry lot. A fresh replacement cell needs at least one full cycle before the camera's internal model stabilises. Charge to 100% via the OEM charger, shoot until the camera shuts off naturally, then recharge fully — the display should stabilise after that cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333840437338,"sku":"BWCS-KLIC7001-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333840470106,"sku":"BWCS-KLIC7001-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333840502874,"sku":"BWCS-KLIC7001-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KLIC7001-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/rollei-compactline-200-replacement-battery-37v-720mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
