Questions about this item

How long will the 210 mAh capacity last in an AirTag that runs every day?

The cells hold 210 mAh each, so runtime depends on the AirTag's average current draw; divide 210 mAh by that draw to estimate days of continuous use.

Do these CR2032 cells get hot or leak after months inside a car key fob?

They are mercury-free with a leakproof design and rated for -4 °F to 140 °F, so normal fob temperatures will not cause heating or leakage.

What device do I already need so the 20-pack can power it?

Any device that takes a CR2032, DL2032, ECR2032, KCR2032, BR2032 or LM2032 3 V lithium coin cell — such as an AirTag, car fob, garage opener or flameless candle.
