Can someone recommend reliable battery source for Lenovo Thinkpads for EU? I am particularly looking for aftermarket battery and for those specific models at the moment. However, it can be extended to general laptop batteries.
I’d say to check directly at iFixit store for this kind of spare parts in general. Not cheap, but it’s most of the time genuine parts, and if not, pretty good quality ones.
Historically I’ve tried to buy replacement batteries directly from Lenovo whenever possible, as I tend to think of the device’s manufacturer as the most reliable source of its batteries. However, I’ve used encompass.com for replacements on numerous occasions, and have found them to be equally reliable (though they have been slow on occasion).
You can select the country you’re in via the settings at the bottom of the page.
I have never purchased a legit Lenovo battery, but I purchased a generic battery for my thinkpad T430 on Amazon.
There were a few generic seller brands, but this is in North America. I'm not sure if European Amazon offers the same options, but it's worth a look.
