3rd party batteries, recommendations

[Olangu]

I'm looking to buy new batteries for my t430s.
(Recently bought a genuine Ultrabay battery just to find out that it - due to old age - only carried 90% capacity.)

Want to know if anyone have any recommendations on third party cells of high quality.
I live in northen europe and mainly looking to buy intra EU, but Asian suppliers could do as well. North america is out of the question as that usually equals high shipping costs as well as extra customs charges.

I've found a supplier of "VINITECH" cells on ebay, and the price is very good. Anyone familiar with that brand?

I also trying to find Ultrabay batteries but still no luck.

Please share your experiences.

90% capacity is awesome for a battery that's even 1-year old.

I have several year old, used batteries that have 95%+ capacity.

You probably only think they have 95%+ capacity, because you never tried to run them down fully. If you did, you would find out that it suddenly reports much lower capacity, or that it suddenly jumps from like 30% to 5%.
