Nominally 7.5 volts is.
alkaline AAA = 1.5 volts
1.5 volts
1.5 volt AAA
They both involve batteries.
No, the capacity of the battery is too low to be of any use.
The familiar 1.5-volt zinc-carbon AAA, AA, C, and D cells, and the familiar 1.2-volt alkalines in the same sizes, are each a single cell.
He introduced alkaline manganese cells in a new battery size, the AAA.
The larger batteries are able to produce more current, and will last longer before they die.
A CR2032 battery is a flat battery, about the size of a thick US0.25$ piece: 20 mm across, 3.2 mm thick. The name of the battery is derived from these dimensions: 20 and 3.2 gives 2032. Other batteries in the CR20XX series are CR2020 (2.0 mm thick) and CR2016 (1.6 mm thick). All these batteries are 3 volt (nominal). This is not AAA-sized (10.5 mm across, 44.5 mm long). Also, an AAA battery is 1.5 volt (nominal).
An ordinary AAA, AA, C, or D sized battery cell will provide 1.5 volts when fully charged. Take it from there!
6 @ 1.5v each The 9 volt battery is a true battery, containing six cells of 1.5 volts each. Most storage devices that we call batteries(i.e. D-cell, AA-cell, AAA-cell) are not batteries, but cells.
