It fits the compact body slot directly and connects via the standard contact plate. Voltage and cell dimensions match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDZ-HV584E, SB-360, and PB-360T compatibility:\u003c\/strong\u003e\n    These three models share the same 3.7V contact footprint, connector orientation, and BMS communication protocol, which is why one cell covers all three. The physical dimensions — 39.50 × 35.40 × 5.60mm — must sit flush for the battery door to close and the BMS handshake to complete.\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 the DZ-HV584E body. The BMS accepted the cell without error flags, regulated the charge termination correctly at full capacity, and held voltage within the expected range across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the DZ-HV584E body:\u003c\/strong\u003e\n    Perform the first full charge cycle inside the camera body rather than in an external charger. The DZ-HV584E BMS maps its battery-remaining display during this first in-body charge cycle — skipping it can cause the indicator to read inaccurately 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\"\u003eDZ-HV584E battery indicator dropping suddenly during DVD recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DZ-HV584E draws more current during active DVD write cycles than during standby or playback. A new replacement cell at a slightly lower state of charge than the indicator shows can hit the BMS low-voltage cutoff mid-session, causing an abrupt shutdown. This happens because the in-body gauge maps voltage thresholds to the original cell's discharge curve, which may not align exactly with a fresh replacement on the first few cycles. Charge the cell fully to 4.2V before each recording session and run two or three full charge-discharge cycles to let the gauge calibrate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body showing dead battery on a replacement cell that just came off the charger\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DZ-HV584E BMS can reject a new third-party cell on first install, displaying a dead or no-battery indicator even when the cell is fully charged. This is a one-time authentication check — the body has not yet accepted the new cell's voltage signature. Remove the battery, reinsert it, then power the camera on without pressing record. If the indicator still reads empty, place the cell in the camera and connect the AC adapter to run one in-body charge cycle from whatever state the cell is currently in, then remove the adapter and power on normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333840076890,"sku":"BWCS-KLIC7001-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333840109658,"sku":"BWCS-KLIC7001-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333840142426,"sku":"BWCS-KLIC7001-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KLIC7001-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/hitachi-dz-hv584e-replacement-battery-37v-720mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
