Standards and common names
IEC designations describe standardized electrochemical systems and forms. Common size names and ANSI or manufacturer numbers may coexist on the same package.
Aliases are not guesses
An alias belongs to a canonical profile only when a published cross-reference supports it. Similar-looking codes stay separate until identity is established.
Search strategy
Search the longest complete marking first, including prefixes and suffixes. Use a short numeric code only when that is all the cell provides.
This guide narrows a battery decision but does not override the device manufacturer’s current manual or safety instructions.
