It fits the Luxmedia 10XS, 12XS, 7203, and over 19 additional models that share the same NP-900 form factor. Voltage and cell dimensions match OEM spec exactly: 43.70 × 31.30 × 7.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared NP-900 platform:\u003c\/strong\u003e\n    Praktica used the same NP-900 voltage rail and connector footprint across the Luxmedia compact range. Any model in that family draws 3.7V from the same cell slot, so one replacement covers the full lineup without adapters or modifications.\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 Luxmedia body. The BMS handshake completed without error codes, and the cell held steady voltage through both still capture and short video bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle BMS initialisation:\u003c\/strong\u003e\n    Run the first charge inside the camera body or OEM charger rather than a generic USB adapter. Some Luxmedia BMS firmware requires one in-body charge cycle before it will report an accurate battery-remaining percentage on screen.\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 on the Luxmedia display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Luxmedia uses voltage thresholds to estimate remaining charge and maps those thresholds to the discharge curve of the original cell. A new NP-900 replacement has a slightly different discharge curve at the top and bottom ends. The camera reads that mismatch as erratic percentage changes — typically jumping from high to low during the first one or two cycles. Run two full charge and discharge cycles in the camera body and the BMS recalibrates its threshold mapping to the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a fresh NP-900\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Luxmedia's flash capacitor pulls a short high-current spike to recharge between frames. When the cell voltage sags — either because the cell is cold or because it is at the tail end of a discharge — the capacitor takes longer to reach full charge. The result is a recycling delay or a visibly weaker flash output on successive shots. If this happens early in a session, check the cell voltage with a meter: anything below 3.5V under load means the cell needs a full charge before further shooting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333824905306,"sku":"BWCS-NP900-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333824938074,"sku":"BWCS-NP900-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333824970842,"sku":"BWCS-NP900-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP900-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/praktica-luxmedia-10xs-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
