AA Battery Spring Contacts — 50 Pack

This pack supplies fifty nickel-plated iron spring contacts sized 24 mm by 11 mm by 0.3 mm. They are designed to sit inside a two-cell AA battery holder and complete the negative-to-positive connection. Each piece weighs about 37 g in total and arrives ready to install.

Makers repairing or building AA battery cases

Hobbyists and technicians who need replacement springs for existing two-slot AA holders will find the quantity and dimensions a direct fit. Buyers who want springs for AAA, C, D or single-cell holders should look elsewhere because the 24 mm length and 11 mm width match only the specified AA format.

24 mm by 11 mm contact footprint

The critical specification is the spring plate footprint of 24 mm by 11 mm with a 0.3 mm thickness, which determines whether it seats correctly in your battery case. Verify your holder’s cavity dimensions against these figures before ordering.

Questions about this item

Will these 24 mm × 11 mm spring contacts fit the AA battery holder I already use?

They are made for 2 × AA battery cases; the 24 mm length and 11 mm width match standard AA slots, so they should seat correctly in existing holders.

How can I confirm the nickel-plated iron contacts are conducting properly once installed?

Insert AA cells, close the case, and measure voltage at the device terminals — a reading that matches the combined cell voltage shows the 0.3 mm thick plates are making solid contact.

The pack lists 50 pieces; does it include any AA cells or a battery case?

Only the 50 silver-tone spring plates are supplied; batteries and the case itself must be purchased separately.
