Very good but pricey

No problem for them who are R06.

Same principle with the possibility to check the state of charge.

We can keep them long enough, maybe not 10 years guaranteed.

What makes me problem is their price. On Amazon, it is easy to buy good quality R06 looted, of Varta in packs of 24 at a price of 7-8.
30 cents / piece on one side, one on the other.
Is the difference in quality of life and possibly justifies this difference?
I doubt it.
Personally, I will continue to buy 24 packs of German competitor.
