AAA Battery Spring Contacts — 50 Pairs
This pack contains fifty pairs of nickel-plated iron spring contacts sized 9.5 mm by 9 mm with a 0.3 mm thickness. They are designed to fit a single AAA battery case box and provide the positive and negative connections inside the holder. The contacts are supplied new and weigh 26 g in total.
Ready-to-install contact plates
Each pair arrives as a finished spring plate, so no cutting, bending or soldering of raw strip is required. The nickel plating protects the iron base from oxidation and maintains low contact resistance over repeated battery changes. Simply press the plates into the moulded slots of a compatible AAA holder.
Suitable for DIY battery holders and repair
Hobbyists building custom AAA packs or repairing damaged battery compartments will find the quantity and dimensions convenient. Buyers needing contacts for AA, C, D or button-cell sizes should look elsewhere, as these plates only match the stated AAA footprint.

Questions about this item
Will the nickel plating on these iron contacts wear through and need replacement?
The contacts are made from iron with a nickeling finish; the thin plating may wear after repeated battery insertions, so plan to swap individual springs if contact resistance rises.
What stops these thin springs from permanently flattening under constant battery pressure?
Each spring is only 0.3 mm thick, so sustained compression in a tight AAA holder can cause permanent set — limit continuous clamping force or rotate spares to avoid loss of tension.
Do the iron springs heat up or add resistance when a device runs all day on AAA cells?
Iron has higher resistivity than copper, so at typical AAA currents the voltage drop across each 9.5 mm contact stays low and noticeable heating is unlikely.
