AD584LH Voltage Reference Battery Adapter (V74PX to AG13 Coin Cell)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4365796.

This battery adapter is designed to adapt 7 x AG13 batteries (also known as LR44, G13, A76, GP76A, 357 & SR44W) to fit a V74PX battery used on some low-cost voltage reference boards using the AD584LH voltage reference.

The 15V, V74PX battery is hard to find and very expensive, so this adapter makes using these cheap reference boards easier and more cost-effective.

WARNING: The voltage reference board requires a supply greater than ~12V to operate, so stacking seven AG13 batteries together (~21V total) is acceptable. If you're looking to use this adapter for other applications, you'll need to print a spacer that takes the place of two batteries.
