Compare watt-hours before milliamp-hours: our BCX204 compatible cell is 1950mAh / 7.55Wh, while the original BCX204 is 1950mAh / 7.55Wh. Milliamp-hours describe charge, not energy, so they cannot be compared across voltage platforms. Watt-hours (voltage x capacity) are the honest figure. Where a label states both a typical and a minimum rating, use the minimum for conservative runtime estimates.
Key specifications and limits: 4K 60p 70–90 min / 1080p 150 min / 1080p 25fps 4 h. Actual figures vary with resolution, frame rate, screen brightness and ambient temperature, so plan spares around the shortest figure in the table.
Original vs our cell, item by item
The table puts the original rating and our compatible cell on the same basis. Price is the listed retail figure; check the product page for current terms. Where a minimum rating is printed, that figure is the better basis for conservative estimates.
| Item | Original | Our compatible cell |

Balancing capacity, price and warranty
Higher capacity does not double your shots: the body cutoff voltage and its fuel-gauge algorithm both shape the reading. For a spare cell, price, cycle life and warranty often matter more than the peak number.

Choosing a kit by shooting load
For light use, one original plus one spare is enough. For a full day of travel or video work, carry two or more and rotate them through a dual-bay charger.

FAQ
Is 1950mAh an inflated rating?
Our BCX204 compatible cell is specified at 1950mAh / 7.55Wh. while the original BCX204 is 1950mAh / 7.55Wh. Compare the Wh figures rather than mAh alone.
Should I look at mAh or Wh?
Wh. Milliamp-hours only become energy once multiplied by voltage, so comparing mAh across different voltage platforms is misleading. 7.55Wh is the like-for-like baseline for this pack.
Can a higher-capacity cell damage the camera?
No. As long as the shell, contacts and protection circuit match the system, capacity only affects runtime. The one caveat is that older bodies may report charge level inaccurately.
Should I buy one cell or two?
For a full day outside or video work, carry two or more and rotate them through a dual dock. For indoor or short sessions, one original plus one spare is enough. Budget conservatively against the Action 4 baseline.
