Battery formulation – IEC codes
- Updated 2025-02-03 01:19 UTC
The open circuit voltage and the capacity of battery depends on what its made of, i.e. its formulation. This table lists the various formulations and the IEC letter used to indicate them, as mention in the Batteries – button cell equivalents and Batteries – dry & alkaline international equivalents tables. Please note that the positive electrode chemicals listed in the table below have hyperlinks linking to their related Wikipedia article.
