It matches the original voltage rail and physical form factor for these video production units. Capacity is 12.6Wh as rated — sourced to match the OEM specification, not exceed it.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG3 \/ AGEZ series platform fit:\u003c\/strong\u003e\n    These models share the same 6V power architecture and battery compartment dimensions. The connector pinout and BMS handshake protocol are consistent across the range, so one cell works across the group without modification.\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 camcorder hardware. The BMS accepted the cell without fault flags, and voltage held within spec throughout the discharge curve under continuous video load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle for camcorder BMS acceptance:\u003c\/strong\u003e\n    Perform the first full charge through the OEM charger or camera body before shooting. Some Panasonic camcorder BMS systems require one internal charge cycle to calibrate the battery-remaining indicator accurately against a 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\"\u003eDead battery indicator showing on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePanasonic camcorder bodies map battery percentage against a stored discharge curve from the original cell. A new Ni-MH replacement has a slightly different discharge profile, so the body's threshold check can read a partially charged cell as empty. This is a calibration mismatch, not a fault with the cell. Run one full charge-to-discharge cycle inside the camcorder to let the BMS remap its thresholds against the new cell's actual voltage curve.\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\"\u003eNi-MH cells have a flatter discharge curve than Li-ion, which makes voltage-based percentage gauges less precise — especially mid-charge where the voltage plateau is narrow. The camcorder body reads small voltage dips under record load as large capacity drops, then corrects upward when load eases. This produces the jumping readout. It does not affect actual capacity delivered. After two full charge cycles, the BMS recalibrates and the display stabilises around a consistent voltage reference point near 5.4V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333895323738,"sku":"BWCS-NP55-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333895356506,"sku":"BWCS-NP55-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333895389274,"sku":"BWCS-NP55-3","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP55-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/panasonic-ag3-replacement-battery-6v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
