It fits a wide range of Panasonic AG-series professional video cameras, including the AGBP15, AGBP15P, AGBP25, and AGEZ1. Cross-references include CGR-B\/202, VW-VBD1, VW-VBD2, and PV-DBP5, among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG-series platform compatibility:\u003c\/strong\u003e\n    These Panasonic camcorders share the same 7.4V rail, InfoLithium-style connector footprint, and BMS handshake protocol. The AG-BP15P pack form factor is consistent across the AG and VW-VBD series, which is why a single cell covers over 240 models in this line.\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 AG-series hardware. The BMS accepted the pack without error flags, voltage sat steady across the discharge curve, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on AG-series camcorders:\u003c\/strong\u003e\n    Before shooting, run one full charge cycle using the OEM Panasonic charger or the camera body itself. Some AG-series BMS firmware needs this cycle to calibrate the battery-remaining display and confirm cell authentication — skipping it can cause erratic percentage readings from the first shot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy AG-series cameras show a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic AG-series firmware maps the battery-remaining display against a voltage-threshold table tuned to the original OEM cell's discharge curve. A new third-party cell discharges at a slightly different rate across the 7.4V nominal range. The camera reads the voltage at a mid-point on the curve, compares it against the wrong threshold, and flags a low-battery warning even when the cell has substantial charge remaining. One full charge-discharge cycle in the camera body usually re-anchors the BMS calibration and corrects the display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the AG-series display mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's internal gauge loses its reference point during sustained video recording — combined sensor, processor, and stabilisation draw pulls current in uneven bursts, and the voltage readings spike and dip faster than the firmware averages them. The display translates those voltage swings directly into percentage jumps. The fix is to let the battery discharge to near-empty in normal use, then charge fully in the body to 8.4V — this resets the gauge's reference points and smooths the readout on the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43336961884250,"sku":"BWCS-SVD250MC-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43336961917018,"sku":"BWCS-SVD250MC-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43336961949786,"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\/panasonic-agbp15-replacement-battery-74v-2900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
