In my project I need a battery with a cylinder of 10mm diameter and 35mm high. I thought only Lithium Polymer technology can create battery for this size. Now I discovery Lithium-ion can have the same size!
Both are very equal in voltage and capacity. But, the capacity is critical and if I can win 10 mAh for the same size, I will choice this technology.
So, is it easy to say what technology is better? Or it depend from manufacture? Or even: The differences are so small that it doesn't matter what I choice?
