Q: Do batteries expire? A: Yes, all good things must come to an end. To find the Best If Used By (BIUB) date of the batteries in question, please look on the uppermost section of the cells, near the battery type (AA, 9V, etc.). … The battery may function beyond that date but with lower performance.

What lasts longer AA or AAA batteries?

That’s where battery size comes in. The D size battery will deliver more current than the C, AA, and AAA size battery. So even if a AA battery and a AAA battery are both rated as having a voltage of 1.5, the AA battery will deliver more current than the AAA battery.
