Battery planner

How many batteries do you need?

Set how much you shoot or film in a day – the planner works with the figures from Sony for the Alpha 7 II.

Photos per day 800 Allow for a reserve – one extra batteryAccording to Sony, battery life is shorter in cold places, with frequent use of the flash or continuous shooting, frequent switching on and off, greatly increased monitor brightness, when the ‘Remote Ctrl’ setting is left on (power saving mode then does not work), and as the battery ages.

Guide value

3battery charges

Battery in the camera + 2 spare batteries – for example, the twin pack.

A guide value, not a guarantee: based on approx. 270 shots using the viewfinder per battery charge (CIPA figure from Sony for the Alpha 7 II, a standardised comparison test) or approx. 60 minutes of video (CIPA, actual recording with image quality 60i 17M (FH)). According to Sony, the actual runtime depends on the conditions of use; we have not measured these figures with Baxxtar batteries.
