Why Do Batteries Come In Different Sizes. The sizes have individually colored tabs which are an industry standard. The nominal voltage of a battery depends on the chemical reaction behind it.
Hearing aid batteries come from a range of manufacturers including leading brands such as. So we know the nominal voltage of alkaline battery is 15V. A lithium coin cell battery will output 3V.
This guide will help clarify things for you.
Note the 14500s cannot be used in all AA devices unless they support both 37 and 15 volt batteries. One advantage that NiCad batteries have over alkaline batteries aside from being rechargeable is that they do not suffer from significant voltage drop when their charge gets low. This is partly due to battery chemistry and partly due to customer demand. Hearing aid batteries come from a range of manufacturers including leading brands such as.
