20-piece AA battery contact kit

This kit supplies twenty nickel-plated iron spring contacts designed for AA battery compartments. Each piece measures 28 by 12 by 0.3 millimetres and weighs roughly seventeen grams in total. They are intended for builders or repairers who need to replace worn contacts in two-cell AA holders. No batteries are included with the pack.

Conductivity and durability

The iron base with nickel plating provides reliable electrical conductivity for everyday low-power devices. Because the contacts are simple metal strips, they add no active thermal load and produce no audible noise during normal operation. Power draw is determined entirely by the attached device rather than the contacts themselves.

Replacing worn or missing springs

These plates restore function to battery boxes where the original springs have corroded, bent or been lost. The upgrade is worthwhile when a device fails to make consistent contact but the enclosure and electronics remain sound. They are not suitable for single-cell holders, larger cell formats or applications requiring soldered PCB terminals.

Questions about this item

How do I fit the 28 x 12 x .3mm spring contact into a 2 x AA battery case box?

Slide the silver-tone iron plate into the compartment so the curved end presses against the cell’s positive tip; the flat face must sit flush with the plastic wall or the lid will not close.

Will the nickeling layer on these 20 contacts wear through and need replacement?

The nickeling resists oxidation under normal indoor use; swap a plate only if the spring loses tension or the surface shows green corrosion after repeated cell changes.

At what point does the .3mm thickness limit current flow in a sustained load?

The thin cross-section suits typical AA devices; expect voltage drop to appear first if the circuit draws more than a few hundred milliamps continuously.
