It fits the VLH100L, VM-645LA, VM835LA, and over 105 additional Hitachi video camera models. Swap it in when the original cell stops holding a charge or fails to register in the camera body.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVM-BPL platform compatibility:\u003c\/strong\u003e\n    The VLH100L and VM-series camcorders share a common 7.4V battery bay and BMS handshake across this model range. OEM part numbers M-BPL13, VM-BPL27, VM-BPL60, and variants all map to the same connector and communication protocol — that is why one replacement cell covers this wide a fit list.\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 a VM-series body. The BMS accepted the cell without fault codes, balancing stayed within spec across the discharge curve, and the protection circuit tripped correctly at the low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on Hitachi camcorder bodies:\u003c\/strong\u003e\n    Charge this cell fully inside the Hitachi body or OEM charger before your first recording session. Some Hitachi BMS firmware requires one complete charge cycle from within the camera body to calibrate the battery-remaining indicator accurately — skipping this often causes the display to read erratically from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VLH100L battery-remaining indicator reads incorrectly after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eHitachi camcorders map their battery-level display to a voltage-threshold curve stored in the BMS firmware. A new third-party cell has a slightly different discharge curve than the original — the voltage sits higher at mid-charge, so the indicator misreads available capacity. This is not a fault in the cell. Run one full charge-to-discharge cycle through the Hitachi body and the BMS recalibrates its reference points. After that cycle, the remaining-charge display tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHitachi camcorder showing dead-battery indicator on a cell that just came off the charger\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage has dropped below the camcorder BMS's minimum recognition threshold — typically below 2.5V per cell — usually from sitting discharged in storage. The camera body sees the low voltage and refuses to power the device rather than attempt a charge. Connect the battery to the OEM charger directly, not the camera body — most standalone Hitachi chargers will trickle-charge a deeply discharged pack back above the 2.8V–3.0V threshold. Once the charger shows a charge in progress, let it complete the full cycle before reinserting into the camera body.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333666177114,"sku":"BWCS-SVD250MC-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333666209882,"sku":"BWCS-SVD250MC-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333666242650,"sku":"BWCS-SVD250MC-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVD250MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/hitachi-vlh100l-replacement-battery-74v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
