Button-Cell Battaries - is there any system to their names?

There is a naming system, but not all companies adhere to it. For example, a Panasonic-produced device may use a standard CR2032 battery but refer to it as PAN04. This mis-naming is a used to frighten consumers into buying only PAN04 batteries. Actually, I just made up that example. I do not know whether Panasonic practices such tactics.

The bottom line: most of the batteries you'll encounter have another, industry standard, name. And buying generically-manufactured batteries is much cheaper than the name-brand.

Let's examine the name "CR2032". This coin-cell battery is composed of Manganese dioxide and measures 20mm in diameter, 3.2mm in height. The name "CR2032" is better read as "C-R-20-32". Each of the 4 parts of the name has a different meaning:

As far as the consumer is concerned, any battery of the right dimensions and voltage will work. On that scale, the batteries DL2032, BR2032, KL2032, L2032, ECR2032, 5004LC, KCR2032, E-CR2032, KECR2032 and SB-T15 are all equivalent. They only differ from CR2032 in chemical composition or branding.
