AA Battery Converter Spring Contacts

This pack contains fifty nickel-plated iron spring contacts sized at 26.5 by 12 by 0.3 millimetres. They are designed to convert the negative terminal to a positive contact inside a two-cell AA battery case box. The metal construction provides reliable electrical conductivity for DIY electronics projects or repairs. Batteries are not included with the spring plates.

Check Compatibility Before Ordering

Verify that your battery holder is built for exactly two AA cells and accepts a contact plate of the stated dimensions. The spring thickness of 0.3 millimetres must match the slot depth in your case to ensure proper compression and contact. These converters are unsuitable for single-cell holders, larger battery formats or any application requiring a different spring geometry or base material.

Fifty-Piece Bulk Pack for Repairs

The quantity of fifty pieces allows multiple conversions or spares for ongoing prototype work without reordering. Each plate weighs a fraction of the total forty-gram package weight, keeping the added mass inside a battery box negligible. The silver-tone nickeling resists oxidation during storage and use, maintaining conductivity over repeated battery swaps in the same holder.
