It fits the VP-HMX10, SC-HMX10A, SC-MX10R, VP-MX10AU, and 17 additional Samsung compact camcorder models. Direct swap for a degraded original cell that no longer holds usable charge during recording or playback.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVP-HMX10 and SC-MX10 series fit:\u003c\/strong\u003e\n    These models share a common 7.4V battery bay, connector pinout, and BMS communication protocol — which is why one SKU covers the full range. The cell dimensions (39.50 × 39.10 × 13.30mm) match the cavity exactly, so the door closes without force.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the VP-HMX10 body. The BMS accepted the cell on first insertion, charge termination triggered cleanly at full capacity, and the battery-remaining indicator tracked consistently through discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on HMX-series bodies:\u003c\/strong\u003e\n    Run the first full charge inside the camera body rather than a standalone charger. The HMX-series BMS maps voltage thresholds to the display indicator during an in-body charge — skipping this step can cause the battery bar to read full and then drop sharply mid-session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VP-HMX10 shows a dead battery icon on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HMX10 body uses a voltage-curve map stored in firmware to estimate remaining charge. A new Li-ion cell has a slightly different resting voltage profile than a worn original, so the camera can misread the state of charge on first use. The indicator may show empty even when the cell is at 60–70% capacity. One full in-body charge cycle recalibrates the map and resolves the mismatch. After that cycle, the display tracks accurately through a normal discharge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's fuel gauge hasn't matched the new cell's discharge curve yet. The VP-HMX10 draws variable current — higher during active recording, lower during standby — and the indicator can spike or drop when the firmware references stale threshold data. It is not a fault with the cell itself. Charge the battery fully via the camera body, run it down to auto-shutoff, then charge again fully. After two complete cycles the percentage reading stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333875400794,"sku":"BWCS-BP85ST-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333875433562,"sku":"BWCS-BP85ST-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333875466330,"sku":"BWCS-BP85ST-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP85ST_1.webp?v=1778213541","url":"https:\/\/batteryweb.com\/products\/samsung-vp-hmx10-replacement-battery-74v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
