It slots into the same battery bay as the original M-BPL30 and shares the same connector pinout. Voltage and capacity match the OEM spec: 7.4V nominal, 2000mAh, 14.8Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVLH100L and VM-series compatibility:\u003c\/strong\u003e\n    These models share a common battery bay and BMS handshake protocol across the VM-BPL13, VM-BPL27, and VM-BPL60 OEM part numbers. The connector, voltage rail, and communication lines are identical across this camcorder family, so one cell covers the full range.\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 a VM-series body. The BMS accepted the cell without error flags on both the OEM charger and in-body charging. Voltage held steady across the discharge curve with no premature cutoff events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on VLH100L:\u003c\/strong\u003e\n    Run one complete charge cycle in the camcorder body — not a standalone charger — before your first recording session. The VLH100L's battery management system maps remaining-charge display against a learned discharge curve, and it needs that in-body cycle to calibrate the indicator correctly.\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 erratically on the VLH100L display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VLH100L uses voltage thresholds to estimate remaining charge and maps those thresholds to a discharge curve it expects from the original cell. A new Li-ion cell has a slightly flatter mid-range discharge curve than an aged OEM battery, so the camera's indicator can misread the state of charge. This causes the percentage to jump — sometimes dropping 20% in seconds, then stabilising. One full in-body charge cycle from flat to full resets the camera's learned curve and corrects the display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamcorder shows dead-battery indicator immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the VM-series BMS hasn't completed an initial handshake with the new cell's protection circuit. The camera reads the cell's state as unknown and defaults to a fault indicator rather than attempting to draw current. Remove the battery, reinsert it firmly, and place the camcorder on charge via the OEM charger for at least 10 minutes. Once the charger confirms cell presence at a stable voltage — typically above 7.0V — the body accepts the cell and the indicator clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333898305626,"sku":"BWCS-SVBD1-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333898338394,"sku":"BWCS-SVBD1-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333898371162,"sku":"BWCS-SVBD1-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVBD1-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/hitachi-vlh100l-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
