2 AA Battery Holder for Arduino/Raspberry-Pi/Robotics

This battery holder can be used for two AA batteries .
A battery holder is one or more compartments or chambers for holding a battery. For dry cells, the holder must also make electrical contact with the battery terminals. For wet cells, cables are often connected to the battery terminals, as is found in automobiles or emergency lighting equipment.

A battery holder is either a plastic case with the shape of the housing molded as a compartment or compartments that accepts a battery or batteries, or a separate plastic holder that is mounted with screws, eyelets, glue, double-sided tape, or other means. Battery holders may have a lid to retain and protect the batteries, or may be sealed to prevent damage to circuitry and components from battery leakage. Coiled spring wire or flat tabs that press against the battery terminals are the two most common methods of making the electrical connection inside a holder. External connections on battery holders are usually made by contacts with pins, surface mount feet, solder lugs, or wire leads.
Where the battery is expected to last over the life of the product, no holder is necessary, and a tab welded to the battery terminals can be directly soldered to a printed circuit board.

Material:-

Most current battery holders are made with polypropylene or nylon bodies rated for 80-100°C. Lithium coin cell holders are made with high temperature PBT, nylon or LCP bodies because they normally are circuit board mounted and require wave soldering at 180-240°C or reflow at 260-300°C.

Battery contacts are the most important part of the design and require serious consideration. Since batteries are nickel plated, it is recommended the contacts be nickel plated to prevent galvanic between dissimilar metals. Battery contacts may be fixed contacts, flexible contacts, or some combination of the two.
Note:- it should be come in white Color.
