Camera Battery Budget

Find how many batteries you need for a planned number of shots.

About Camera Battery Budget

Dividing planned shots by the realistic capacity of one battery and rounding up gives the batteries to bring, with spare capacity counted. Carrying enough batteries avoids running out mid-event, which is especially critical on shoots without recharging options.

Formula

Camera Battery Budget

Batteries = ceil(planned shots / shots per battery)

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
