It replaces OEM references CGR-B\/202, CGR-B\/202A1B, VW-VBD1, VW-VBD2, PV-DBP5, and several others. The cell and BMS are matched to the voltage rail these camera bodies expect.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG-BP15P platform compatibility:\u003c\/strong\u003e\n    These Panasonic camcorder bodies share a common 7.4V bus and use the same multi-pin connector with a BMS handshake that checks cell voltage on insertion. One battery design covers the full range because the BMS protocol and connector pinout did not change across these production runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the AG-BP15P body and monitored BMS communication at the connector. The protection circuit engaged correctly at low-voltage cutoff and the camera accepted the cell without error flags on cold insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the AG-BP15P:\u003c\/strong\u003e\n    Run the first full charge cycle through the camera body itself, not a third-party charger. Some Panasonic camcorder BMS units need an in-body charge pass before they map the new cell's discharge curve correctly and display an accurate remaining indicator.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the AG-BP15P battery indicator reads incorrectly after replacing the cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic's fuel gauge on these camcorder bodies maps remaining charge against a stored discharge curve learned from the previous cell. A new replacement cell with a slightly different internal resistance profile causes the camera to misread state-of-charge, especially in the upper 80–100% range. The BMS recalibrates after one or two complete discharge and charge cycles performed through the camera body. Until then, treat the indicator as approximate and work from actual shooting behaviour rather than the percentage readout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body showing dead battery on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell arrives in a low storage state and the camera's BMS reads the resting voltage as below its acceptance threshold. The fix is straightforward: place the battery on the OEM Panasonic charger first and bring it to at least 7.0V before inserting it into the body. Once the camera sees a voltage it recognises as a valid starting point, it stops rejecting the cell. If the body still shows no battery after a full charge, check the connector pins on both the battery and the camera for debris or corrosion — the BMS handshake is a contact-sensitive signal line.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43336961720410,"sku":"BWCS-SVD280MC-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43336961753178,"sku":"BWCS-SVD280MC-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43336961785946,"sku":"BWCS-SVD280MC-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVD280MC-1.webp?v=1778213032","url":"https:\/\/batteryweb.com\/products\/panasonic-agbp15-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
