Shop around for AA and AAA batteries and the main types you’ll find are alkaline and lithium disposable batteries. This battery contained two independent 4.5V batteries, and had a four-pin connector. 9V with a center tap was available by wiring in series. There were two ⌀3.2mm negative pins spaced 9.5mm apart and two ⌀4.0mm positive pins spaced 14.3mm apart. Negative and positive pins were spaced 18.1mm apart. It was used in some early transistor radio amplifiers with a Class B output stage, allowing the loud speaker to be connected between the amplifier output and the battery center tap. Our tough lab tests have uncovered big differences between the best AA batteries and the worst. Use our results to make sure you don't waste your money. This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series.
We’ve tested batteries from Aldi and Lidl – which can cost as little as 26p per battery – alongside big brands Duracell and Energizer to see how they match up. Only our tests reveal whether buying cheaper batteries will save you money and hassle. Bergveld, H; Kruijt, W; Notten, P (February 1999).

This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.Coin-shaped cells are thin compared to their diameter. Polarity is usually stamped on the metal casing.

AA alkaline batteries are very much the ‘standard’ type, sold incredibly widely in all sorts of places, and are usable in almost any relatively low-powered consumer electronics device.The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. [1] Button cells, also known as watch batteries, coin batteries, or small single-cell batteries, have a squat cylindrical shape and are typically 1 to 6 mm (0.039 to 0.236 in) high and 5 to 25 mm (0.0197 to 0.984 in) in diameter, resembling a button. Battery cells do not come as rechargeable batteries.
