Vintage PP3-size 9-volt batteries Size comparison of batteries: D, C, AA, AAA, AAAA, 9-volt (PP3) The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a ...
Introduced 1898 as the first flashlight battery. Can be replaced with an AA cell or a C cell using a plastic sabot (size adaptor), with proportional loss of capacity. F: R25 (carbon‑zinc) LR25 (alkaline) 60: 10,500 (carbon‑zinc) 26,000 (alkaline) 1.5: 33 × 91 Four F cells are often found within 6-volt rectangular lantern batteries. N: Lady ...
These batteries are not as popular as AAA or AA type batteries, and consequently are not as commonly available. Some models of alkaline nine-volt battery contain six LR61 cells [4] connected by welded tabs. These cells are similar to AAAA cells and can be used in their place in some devices, even though they are 3.5 millimetres (0.14 in) shorter.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
A Duracell AA size alkaline cell, one of the many types of battery This list is a summary of notable electric battery types composed of one or more electrochemical cells . Three lists are provided in the table.
The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.
