Same footprint as the OEM cell at 40.20 × 35.30 × 6.10mm — fits the battery bay without modification. Use it when the original cell no longer holds a charge or the camera stops powering on mid-shoot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLife P42010 \/ P42012 \/ MD85866 \/ MD85416 platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector orientation, and 3.7V BMS voltage threshold — one cell covers all of them without adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Medion camera body and an OEM-spec charger. The BMS accepted the cell, voltage stayed within the 3.7V nominal band, and charge termination triggered cleanly at capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge protocol for Medion compact cameras:\u003c\/strong\u003e\n    Run the first full charge cycle inside the camera body using the OEM charger — not an aftermarket multi-charger. Some Medion BMS firmware maps the battery-remaining indicator during this first in-body charge cycle. Skipping it causes erratic percentage readings in the field.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThe Medion Life P42010's battery indicator reads voltage thresholds mapped to the original cell's discharge curve. A new cell often sits at a resting voltage of 3.6–3.65V out of the packaging — low enough that the camera reads it as empty. This is a voltage-mapping issue, not a cell fault. Charge the battery fully in the camera body first; once the BMS logs a complete charge cycle, the indicator tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe flash capacitor in compact cameras like the Life P42010 draws a sharp current spike to recharge between exposures. If the cell voltage has sagged — even slightly — the capacitor recharge slows down and the camera delays the next shot or fires an underexposed flash. This typically appears when the cell is below 3.5V under load. If recycling lag appears early in a session on a new battery, check that the first full charge cycle completed properly; a partially initialised cell sags harder under flash load than a fully cycled one.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333853085786,"sku":"BWCS-NP40FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333853118554,"sku":"BWCS-NP40FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333853151322,"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\/medion-life-p42010-replacement-battery-37v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
