Compare watt-hours before milliamp-hours: our DMW-BLK22 compatible cell is 2520mAh / 19.24Wh, while the original DMW-BLK22 is 2200mAh / 16Wh. 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.
By CIPA standard the S5 II delivers about 370 shots per charge (4K 60p 90 min). Real-world figures fall with viewfinder use, bursts, flash and low temperature, so budgeting around 70% of the rating is safer.
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 |
|---|---|---|
| DMW-BLK22 | 2200 mAh | 2520 mAh |
| Wh | 16 Wh | 19.24 Wh |
| mAh (min) | — | 2400 mAh |
| CNY | — | ¥78.3 |
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 2520mAh an inflated rating?
Our DMW-BLK22 compatible cell is specified at 2520mAh / 19.24Wh. The label also states a minimum of 2400mAh. while the original DMW-BLK22 is 2200mAh / 16Wh. 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. 19.24Wh 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 S5 II baseline.
