It fits a wide range of models including the AGBP15, AGBP15P, AGBP25, and AGEZ1, among others. Voltage, connector, and BMS handshake match the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG\/VW platform compatibility:\u003c\/strong\u003e\n    These Panasonic camcorder lines share a common 7.4V battery rail, connector housing, and communication protocol. The CGR-B\/202 cell family covers both compact AG shoulder-mount units and handheld VW-series camcorders because the BMS expects the same voltage curve and data-line response across all of them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on bench equipment and confirmed the BMS handshake initiated correctly, the protection circuit responded to simulated over-discharge, and voltage recovery after load matched the OEM discharge profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle for accurate metering:\u003c\/strong\u003e\n    Insert the battery into the camera body and run a full charge through the OEM charger or in-body charging circuit before heavy recording. Panasonic's battery-remaining indicator maps to a learned voltage curve — skipping this step can cause the display to misread remaining capacity on the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AGBP15P shows a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic's battery gauge on this platform reads remaining charge by mapping terminal voltage to a pre-stored discharge curve. A new Li-ion cell has a slightly different resting voltage signature until it's been cycled once inside the camera body. The camera's BMS sees an unfamiliar voltage-to-capacity ratio and flags it as low or exhausted even when the cell is at 70–80% charge. One full charge cycle completed through the OEM charger or camera body resets the mapping and brings the indicator inline with actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camera's indicator is referencing a discharge curve that doesn't yet match the new cell's real voltage output under load. Sustained video recording — especially with image stabilisation and continuous autofocus active — creates variable current draw that exposes any mismatch between the stored voltage thresholds and actual cell behaviour. The display compensates by recalculating rapidly, which shows as jumping percentages. Completing two full charge-discharge cycles through the camera body stabilises the curve mapping and settles the readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43336963653722,"sku":"BWCS-SVBD1-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43336963686490,"sku":"BWCS-SVBD1-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43336963719258,"sku":"BWCS-SVBD1-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVBD1-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/panasonic-agbp15-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
