If you are tired of constantly replacing button cell batteries in your digital caliper, this adapter is for you.
This model is a simple AAA battery holder/adapter that allows you to power your digital caliper using a standard AAA battery instead of coin cells. With this setup, the battery now lasts for years instead of weeks or months.
Installation notes:
You need to solder two wires to the + and – terminals inside the caliper
Connect the wires to the corresponding positive and negative sides of the AAA battery
Once installed, the caliper works reliably with a single AAA battery and no longer suffers from the typical button cell drain.
This is a practical upgrade for anyone who uses digital calipers frequently and wants a simple, long-lasting power solution.
