It fits the AG-BP15P, AG-BP25, AG-EZ1, AG-EZ1U, and over 30 additional Panasonic broadcast and documentary camcorders. Voltage and connector pinout match the OEM pack directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG-BP and AG-EZ platform fit:\u003c\/strong\u003e\n    These camcorder lines share a common battery dock format and 7.4V BMS handshake. The cell voltage rail, connector orientation, and communication pins are identical across the AG-BP15P, AG-BP25, and AG-EZ variants — which is why one part number covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an AG-BP15P body and monitored BMS charge acceptance, cutoff behaviour at low voltage, and thermal response under sustained 1080p recording load. The BMS accepted the cell without fault codes across full charge and discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use initialisation on Panasonic camcorders:\u003c\/strong\u003e\n    Insert the battery and run a complete charge cycle through the OEM charger or camera body before shooting. Some Panasonic AG-series bodies require one supervised charge cycle to calibrate the battery-remaining display to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage reading frozen or stuck on AG-BP series bodies\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe AG-BP15P and AG-BP25 use a voltage-threshold system to estimate remaining charge. A new cell's discharge curve sits slightly differently than a worn OEM pack, so the indicator can lock at one percentage for extended periods before dropping. This is a calibration issue, not a cell defect. Run two full charge-to-discharge cycles through the camera body and the gauge will track the new cell's curve accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body warm and battery draining faster than expected under continuous recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained video recording on Panasonic AG-series camcorders draws simultaneously from the sensor, image processor, optical image stabilisation, and viewfinder — combined current draw is significantly higher than single-shot stills use. Heat from the body itself reflects that combined load, not a fault in the cell. If the battery cuts out before expected, check that the body firmware is current, as some AG firmware versions had aggressive low-voltage cutoff thresholds that were revised. Confirm cutoff voltage in diagnostics mode is not set above 6.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333898109018,"sku":"BWCS-SVBD2-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333898141786,"sku":"BWCS-SVBD2-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333898174554,"sku":"BWCS-SVBD2-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVBD2_1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/panasonic-ag-bp15p-replacement-battery-74v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
