Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery device, and particularly to a battery spacer having an outer diameter of a AA battery, which accommodates a battery having an outer diameter of an AA battery, thereby forming a battery having a predetermined shape. In a battery device configured to form a battery having a predetermined shape and size, the battery spacer accommodates up to three batteries having the outer diameter of a AA size battery to form a battery having a predetermined shape and size. The present invention relates to a battery device.

Although the present invention is not limited to nickel-cadmium batteries, nickel-cadmium batteries have recently been developed, and these batteries have low internal resistance, can be rapidly charged in a few minutes to several minutes, and have a large discharge current. Due to the fact that it can be easily obtained, it has become widely used as a power source battery for household electrical equipment.

This type of nickel-cadmium battery is generally small and lightweight, but it can be used effectively, so it has a smaller shape and size compared to commercially available 1-type and AA-size manganese batteries. It is being

Therefore, for example, the nickel-cadmium battery mentioned above is
When the nickel-cadmium battery is used as a power source by inserting it into a battery housing case that houses a type battery, a battery spacer having a shape and size equal to the standard dimensions of the AA type battery is added to the battery housing case. We are trying to accommodate the following.

However, for example, if a battery spacer is added to a single nickel-cadmium battery whose shape and dimensions are the same as the standard dimensions for an AA type battery, a battery spacer is added to form a AA type battery, and this battery has a discharge current of 230 m
, when used as a power source for the cassette recorder of A.
Compared to using one AA-size manganese battery as the power source for the cassette recorder, the nickel-cadmium battery can be used continuously for about 1 hour.
On the other hand, it is known that the continuous usable time of the above-mentioned AA type manganese dry cell battery is approximately 8 hours.

As described above, a nickel-cadmium battery having the outer diameter of a AA-size battery has the disadvantage that it can only be used continuously for a relatively short period of time compared to a AA-size manganese battery.

Therefore, the above-mentioned problem can be solved by producing a nickel-cadmium battery with a large charge/discharge capacity by giving the outer diameter dimensions of a single-cell battery, but this is generally undesirable due to the high cost.

The present invention aims to solve the above-mentioned problems and generally consists of a single device.
The outer diameter of the battery is 32.2 mm, ~34.2 mm.

The outer diameter of the SI3 type battery is 13.5mm.
Focusing on the fact that the standard is ~14.5 mm,
Relatively low cost can be achieved by using the battery spacer to accommodate up to three batteries (for example, nickel-cadmium batteries) that have the above-mentioned outer diameter dimensions of AA-type batteries in the battery spacer. The object of the present invention is to provide a battery device that can be used for a relatively long time.

This will be explained below with reference to the drawings.
