Unique-Bargains AA Battery Converter Spring Contacts 50 Pcs 28x12mm Silver Tone

SKU CH-YNYN-HXNJE

Fifty nickel-plated iron spring contacts convert a single AA slot into a dual-cell holder, each measuring 28 by 12 millimetres

  • Battery TypeBattery Converter
  • 50 pieces supply multiple battery-case builds
  • nickel-plated iron gives reliable conductivity
  • 28 × 12 × 0.3 mm fits standard AA holders
  • 45 g total weight keeps projects light
  • silver-tone finish resists corrosion in use

Purpose & Fit

These spring contacts convert the polarity of two AA cells inside a battery case box. The pack contains fifty pieces, each sized 28 by 12 millimetres with a 0.3 millimetre thickness. They are intended for hobbyists, repair technicians or small-scale assemblers who build or service custom AA-powered devices. Buyers who need a single contact or a different cell format will not find this bulk pack suitable.

Accessory Impact

The nickel-plated iron plates provide reliable electrical conductivity for the positive-to-negative connection. No batteries, wires, solder or tools are included in the package. The components simply drop into a compatible two-cell holder, reducing assembly time for prototype or repair work. Users requiring pre-wired terminals or insulated housings must source those separately.

Build & Connectors

Each contact weighs a fraction of the total 45 gram pack weight and measures 1.1 by 0.47 by 0.012 inches. The thin profile allows stacking within tight case cavities while the spring tension maintains firm contact under vibration. The silver-tone nickel finish resists oxidation during storage. Installers should verify that their battery box accepts the exact 28 by 12 millimetre footprint before ordering.

Questions about this item

Will the iron spring contacts lose tension or corrode after repeated battery swaps?

The contacts are nickel-plated iron measuring 28 x 12 x 0.3 mm; nickel resists oxidation while the spring steel base keeps its shape through many insertions.

What stops me from fitting these into a holder designed for AAA or D cells?

Each plate is sized for AA only at 28 mm long and 12 mm wide, so it will not align with smaller AAA or larger D compartments.

Do the plates get warm or add resistance when the circuit runs continuously for hours?

At 0.3 mm thick with nickel-over-iron construction the contact resistance stays very low, so no measurable heat appears even under all-day load.
