Battery capacityiPublished pack capacity at the nominal battery voltage. A cell count times a cell capacity, such as "8 x 3,200mAh", is not a pack capacity. The cell capacity is the pack capacity only when all cells are in series. That holds when the pack voltage divided by the cell count is one lithium-ion cell voltage, 3.6 or 3.7 V, such as 8 x 2,200mAh at 29.6 V. The source note shows the check. When the maker gives a rated and a nominal capacity, the one that matches its stated Wh at the pack voltage is stored.

Run time (claimed)iOne row per maker run time claim on one battery. Power level puts the maker's mode on a common scale. Lowest is the weakest setting, such as Eco or Min. Highest is the strongest, such as Boost, Max or Jet. Middle covers every setting between them. Claims that add a second battery are not stored. A handheld configuration without a motorized head counts as non-motorized tool. On hard floor with the main head counts as motorized floor head. Leave the tool out when the maker says neither or its own pages disagree, and name them in the source note. A machine with one power setting uses highest. When the maker gives a range, such as 20 to 25 min, the top of the range is stored and the range goes in the source note. A boost button or trigger counts as a setting, so a machine with one setting and a boost has a lowest and a highest row. A wet cleaning mode, such as Dyson Wet or Samsung WET, is not a power level, so it is not stored.
