Voltage

Rated voltage of a fully charged battery or a fresh battery. The practical value of this parameter may differ slightly from the nominal one, however, in the design of most electronics models, this feature is usually taken into account, and the user himself does not need to worry about this. And in general, voltage data in most cases does not play a key role and is more of a general reference information. This is due to the fact that all sizes (see above) have requirements not only for the overall design of the battery, but also for its voltage. Therefore, it is necessary to pay special attention to this indicator mainly in specific cases, such as searching for interchangeable elements or assembling a home-made electrical circuit and selecting power for it.

Rated discharge current

Rated discharge current provided by the battery. This is the highest discharge current at which the battery will operate without a voltage drop and without a noticeable decrease in the actual capacity. It is worth paying attention to this parameter first of all if the battery is purchased for a device that is sensitive to supply voltage — for example, for a multimeter.

The rated discharge current is indicated only for rechargeable batteries (see "Type").

Maximum discharge current

The maximum discharge current provided by the battery is the maximum current that the battery can deliver without the risk of overloading, overheating and other troubles. This indicator directly determines compatibility with a specific device: the current consumed by the load must not exceed the maximum battery discharge current.

The maximum discharge current is indicated only for rechargeable batteries (see "Type"). By definition, it is greater than the nominal one (see above), but it is worth recalling that when the rated current is exceeded, the voltage at the battery output decreases. Therefore, in some cases, it is necessary to choose a battery exactly according to the rated discharge current.
