What battery do I have

I have six 18650 batteries that I recovered from a 2004 Sony laptop. They work and charge just fine but I have one question. I can't figure out what Mah rating they were originally quoted at.

The original pink wrap identifies them as CGR18650 CA / Li-ion MH12210 (made in Japan). Try as I might I can't find that reference on the Internet. I can find the CGR18650 part but never the CA suffix or the pink wrap.

Anyone got any ideas?

I've had this same issue from the cells themselves. Use the pack label and work backwords to get cell capacity based on voltage,
Wh capacity, and number of cells. In one case (Dell) the pack capacity was not printed on the pack, I had to look it up.

AB8XL. Many thanks. I have no idea why I couldn't find that myself but your help is much appreciated.
