Thanks for the review again :-) , it looks like a decent battery.

What would your guess be?, does this Sibeile company rewrap Panasonics and other batteries (because some perform very similar to existing batteries) or do they make (some of) their batteries themselves? And if they just rewrap, why does such a company exist?

The chinese ways are very unclear to me...

I expect they rewrap, these type of companies are all over the world, not only in China.

While doing the rewrap they often add some value, like protection or button top.

Another job, that some rewrap companies does, is select the good Chinese batteries.
