AA battery spring contacts for DIY cases

This pack supplies fifty nickel-plated iron spring plates sized 28 by 12 by 0.3 millimetres. They convert a positive AA contact to a negative one inside a two-cell battery box. The silver-tone parts weigh 46 grams total and suit hobbyists building or repairing custom battery holders.

Consistent conductivity under repeated insertion

The iron base with nickeling finish maintains low resistance across many mating cycles in a holder. Spring tension stays stable so voltage drop does not increase during sustained use in a two-AA enclosure. No active components are present to degrade over time.

Simple press-fit install with one common mistake

Each plate presses into the moulded slot of a standard AA battery case; no soldering or tools are required. The only frequent error is fitting them into a single-cell or larger-cell holder where the 28-millimetre length does not align. Battery cells are not included.

Questions about this item

Will the spring plate heat up or draw power when left inside a battery case all day?

The plate is a passive metal contact with no active circuitry, so it generates no heat and consumes no power during continuous use.

What existing hardware must I already have to use these 28 x 12 x 0.3 mm spring plates?

You need a 2 x AA battery case box designed for AA cells; the plates fit inside that holder to convert the contact orientation.

Can I keep my older AA devices and battery holders while adding these 50 nickel-plated iron plates?

Yes, the plates work with standard AA compartments and do not change the electrical requirements of legacy equipment.
