There are 2023,2032 and 2025 batteries. My blood test meter calls for 2023. Don't know if the others will work equally well even though they are the same diameter.

The differences are load capacity. See the chart below:

Voltage Capacity
2023 3V 225mAh
2026 3V 163mAh
2032 3V 210mAh

All other specs are the same.
