It fits the same battery bay and connects to the same four-contact interface as the original cell. Swap it in when the factory battery no longer holds a usable charge through a full recording session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGC-S5 and MX-series compatibility:\u003c\/strong\u003e\n    These camcorders share the same 3.7V battery rail, identical four-pin dock geometry, and a common BMS communication protocol — which is why one cell number covers all of them. The BMS on each body reads cell state-of-charge and temperature via the same data line.\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 GC-S5 body. The BMS accepted the cell without error flags, terminated charge correctly at full voltage, and held cutoff at the low-voltage threshold without tripping prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use cycle on the GC-S5:\u003c\/strong\u003e\n    Run the first full charge inside the camera body rather than a third-party external charger. The GC-S5 BMS maps battery-remaining display to its own charge curve — one complete in-body charge cycle calibrates the indicator so it tracks accurately through subsequent discharges.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GC-S5 battery indicator jumps or reads full when the cell is nearly empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GC-S5 maps its battery-level display to a voltage-threshold table built around the original BN-V101 discharge curve. A new replacement cell — even a correctly specced one — can sit slightly off that curve during the first few cycles. The body reads the voltage correctly but translates it to the wrong percentage step. After two or three full charge-discharge cycles inside the camera body, the displayed level tracks the actual cell state reliably.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera showing \"no battery\" or refusing to power on with a freshly installed cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS receives a valid cell voltage but hasn't completed an authentication handshake — common on first install if the cell rested at partial charge during storage. Remove the battery, reinsert it firmly until the latch clicks, then connect the camera to its OEM charger for at least ten minutes before powering on. If the camera still shows no battery, the cell voltage may have dropped below the BMS wake threshold during long storage — charge via the OEM charger first and bring the cell to at least 3.6V before attempting to boot.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333823922266,"sku":"BWCS-NP100FU-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333823955034,"sku":"BWCS-NP100FU-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333823987802,"sku":"BWCS-NP100FU-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP100FU-1.webp?v=1778213259","url":"https:\/\/batteryweb.com\/products\/jvc-gc-s5-replacement-battery-37v-1850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
