It fits the HC-V520M, HC-V110, HC-V130, HC-W570, and over 25 additional Panasonic HD camcorder models. Voltage and capacity match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHC-V and HC-W series compatibility:\u003c\/strong\u003e\n    These Panasonic camcorder lines share the same battery bay geometry, 3.6V power rail, and VW-VBT190 BMS handshake. One cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the HC-V520M body. The BMS accepted the cell, the battery-remaining indicator tracked correctly through most of the discharge curve, and protection circuits tripped at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on camcorder bodies:\u003c\/strong\u003e\n    Charge this cell inside the HC-V series body or an OEM VW-VBT190-compatible charger before your first shoot. Some Panasonic camcorder BMS firmware maps the battery-remaining display during that first full cycle — skipping it can cause the indicator to read inaccurately mid-shoot.\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 or dropping suddenly during HC-V520M recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic's battery-remaining indicator maps voltage thresholds against the OEM cell's discharge curve. A new third-party cell has a slightly different curve, especially in the mid-range. During the first few charge cycles, the camera's BMS recalibrates that map — sudden jumps or drops in the indicator are normal at this stage. After two or three full charge-discharge cycles, the reading stabilises. If it still jumps after that, check resting voltage with a meter: a healthy fully charged VW-VBT190-format cell reads 4.18–4.20V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHC-V520M showing dead battery icon immediately after inserting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not yet completed an authentication handshake with the new cell. It is not a fault in the cell itself. Remove the battery, wait 10 seconds, reinsert, and power on again. If the icon persists, place the battery in an OEM-compatible charger until the charge LED confirms a full cycle — then reinsert into the camera body. A cell that genuinely won't be accepted will still charge normally outside the body; resting voltage after a full charge should read at least 4.15V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333700026458,"sku":"BWCS-HCV310MC-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333700059226,"sku":"BWCS-HCV310MC-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333700091994,"sku":"BWCS-HCV310MC-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HCV310MC_1.webp?v=1778213017","url":"https:\/\/batteryweb.com\/products\/panasonic-hc-v520m-replacement-battery-36v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
