It cross-references against BP-L40, BP-L60, BP-L90, BP-GL95, BP-L90A, BP-L80S, BP-L60A, BP-GL65, BP-L60S, BP-65H, BP-IL75, E-80S, E-70S, E-50S, E-7S, BP-90, and BP-L60S. Capacity is 4400mAh (63.36Wh) at 14.4V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG-DVC200P, AJ-SDX900P, AJ-D410A, AJ-HDC27FP compatibility:\u003c\/strong\u003e\n    All four models share the same 14.4V battery rail, V-mount-style connector footprint, and BMS communication protocol — which is why a single cell covers the full group. The BMS on each body sends a handshake signal to verify voltage and cell chemistry before enabling the discharge circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a DVC200P body and an AJ-SDX900P deck. The BMS accepted the cell without fault flags on both units, and the discharge curve stayed within the expected voltage window across the full cycle from 16.8V peak down to the 11V cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on broadcast bodies:\u003c\/strong\u003e\n    On the DVC200P and AJ-SDX900P, charge this cell once fully inside the OEM charger or camera body before your first shoot. These bodies map their battery-remaining indicator against a learned discharge curve — skipping this step causes the display to read inaccurately until the BMS completes one full calibration cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AJ-SDX900P and DVC200P report incorrect battery percentage on a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic's broadcast-grade BMS uses a coulomb-counting method tied to the cell's historical charge and discharge data. A new cell has no stored history, so the body estimates remaining capacity against a default baseline that rarely matches the actual cell. This causes the indicator to jump or drop suddenly — especially in the final 30% of the display. One full charge cycle inside the camera body or an OEM Panasonic charger writes the initial calibration data. After that first cycle, the indicator tracks the cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body cutting to low-battery warning while voltage is still above 12V\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AG-DVC200P and AJ-D410A set their low-battery cutoff thresholds based on voltage under load — not open-circuit voltage. During heavy record loads, internal resistance in an ageing or cold cell causes a momentary voltage sag that triggers the cutoff even when resting voltage looks fine. If the body throws a low-battery flag during active recording but recovers seconds after you stop, the cell is sagging under load rather than being genuinely depleted. Confirm resting open-circuit voltage with a multimeter — a healthy fully charged cell should read between 16.4V and 16.8V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333916655706,"sku":"BWCS-BPL40-1","price":108.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333916688474,"sku":"BWCS-BPL40-2","price":128.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333916721242,"sku":"BWCS-BPL40-3","price":143.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPL40-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/panasonic-ag-dvc200p-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
