Opened up the milwaukees and look what I found

[DMCfirestar500]

Well I got one pack with white covered cells and one with brown covered cells. Anyone know if theres a difference?

The brown cells read: Moli FSPE70045.2715 08

The white cells read: Moli FSPE70045.0176 10

I'll ask on some other forums as well and post any findings here.

Thats odd. Are they part # the same?

[DMCfirestar500]

Well the numbers I listed in the first thread are the numbers on the cells that differ. But below them there is a line that reads IMR-26700A Made in Canada which reads the same on both color cells. I'm hoping that moli just used different color wraps, but the same cells.

From what I understand, the brown cells use steel positive tabs, and the white ones use aluminum. I don't think it would affect your performance to mix the two.

You need special solder flux to solder to aluminum. When you use it, it makes a TON of smoke, like solder smoke times 20!

I think that the aluminum is plated with something (maybe nickel?) that makes it easier to solder to.

[Tazz]

Yes, the aluminum is plated. When you clean them to solder do not remove the plating or you will have to do as MetalMan said.
