I just cracked open an old Acer laptop battery, and I found these four 18650s inside. My attempts at Googling what I assume to be the model number proved unsuccessful. Each one has the same JGLFH35 printed on it, and then an individual unique number listed below that line. There's also a stamped J33A in the side of each pink/red wrapper. The letter "F" is stamped into the negative terminal. The Sharpie writing is my addition.
The casing of the laptop battery said that they were Sanyo cells, and it listed a rated capacity of 2000 mAh for the entire pack. So only 500 mAh for each cell, if I'm not mistaken. That seems really low to me for an 18650, but I'm just beginning to learn about lithium ions, so honestly I could be way off.
Any info (or random thoughts) would be appreciated.
