It matches the original cell's voltage rail and physical footprint — 40.20 × 35.30 × 6.10mm — so it seats correctly in the battery compartment without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDA10 \/ DB60 \/ DP60 \/ DX63 platform fit:\u003c\/strong\u003e\n    These models share the same battery cavity dimensions and 3.7V power rail, which is why one cell covers all of them. The connector polarity and BMS communication protocol are consistent across this Rollei compact series.\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 camera-class draw loads. The BMS held stable cutoff at low-voltage threshold and accepted charge via both OEM charger and camera-body charging paths without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on camera body:\u003c\/strong\u003e\n    Insert the new cell and run one full charge cycle through the camera body itself before heavy shooting. Some Rollei compact BMS systems calibrate the battery-remaining indicator against the new cell's discharge curve only after this initial in-body charge cycle.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Rollei DA10's battery indicator maps voltage thresholds to its own discharge curve table stored in firmware. A new replacement cell has a slightly different internal resistance profile than the aged OEM cell the camera was last calibrated against. This mismatch causes the indicator to read the cell as empty when it still holds usable charge. One full charge-discharge cycle through the camera body resets the reference point, and the indicator reads correctly from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during a shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings on compact cameras like the DA10 are a voltage-mapping issue, not a defective cell. The camera's fuel gauge samples terminal voltage and compares it to a fixed discharge curve — when the new cell's curve doesn't match the stored table exactly, the percentage can jump several steps up or down between shots. Flash recharge draws a short high-current pulse that drops terminal voltage sharply, which the firmware can misread as a sudden capacity loss. Complete two full charge cycles in-camera, then verify the display stabilises above 3.6V at what the camera reports as 20% remaining.\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333854298202,"sku":"BWCS-NP40FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333854330970,"sku":"BWCS-NP40FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333854363738,"sku":"BWCS-NP40FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP40FU-1.webp?v=1778213292","url":"https:\/\/batteryweb.com\/products\/rollei-da10-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
