AA Battery Spring Contact Plate — 50 Pairs

This pack contains fifty pairs of nickel-plated iron spring plates sized 12 by 12 by 0.3 millimetres for AA battery compartments. They provide the positive and negative contacts inside a single-cell holder. Each plate weighs about forty-six grams total. The silver-tone finish resists oxidation for reliable conductivity.

Practical limits of the spring contact format

The plates fit only a one-cell AA battery case and cannot be used for multi-cell packs or other chemistries. Their thin 0.3 millimetre profile suits compact holders but offers no structural support beyond electrical contact. No batteries are included, so a separate cell must be sourced. The nickel coating protects the iron base from corrosion in normal indoor use.

What to check before ordering

Verify that your battery case accepts a 12 by 12 millimetre contact plate and is designed for a single AA cell. Confirm the holder's polarity layout matches a positive-negative pair arrangement. Ensure the 0.3 millimetre thickness does not exceed the compartment's clearance. The plates are sold as components, not complete holders.

Questions about this item

How do I decide between ordering one pack or multiple packs of the 50-pair spring contact plates?

Each pack contains 50 pairs of plates weighing 46 g total, so count how many AA battery compartments you need to equip and order enough packs to cover them.

What does the 12 mm by 12 mm by 0.3 mm size mean when I fit the plate into an AA battery holder?

The plate measures 12 mm long, 12 mm wide and 0.3 mm thick, matching the footprint of a standard AA cell so it sits flush inside the holder and makes reliable contact.

The plates are iron with nickeling — what does that surface finish actually do for conductivity and durability?

The nickel coating on the iron base improves electrical conductivity and resists oxidation, giving a stable, low-resistance connection over repeated battery swaps.
