Excuse me ... maybe it is I who do not explain myself well, "globalization" requires choices of "saving on a large scale"; that is ... If you have to sell a vehicle and make a certain profit where are you going to save? On external components, clutch, brakes, tires, plastic parts, cables and batteries.
And how are you going to assemble good brand components while saving money? The top brand supplier will have factories in countries where the component is cheaper and will allow him to make a better offer to the manufacturer but the quality will be "fair" and of average duration, however sufficient to satisfy the customer of the final product.
If they don't do this, they fall behind in the race to sell, unfortunately it is now a discipline followed by many brands.
You may have wondered why some customers are better and others worse ... Well ... Many factors in the field including a dose of luck, chance and how the vehicle is used; you have read in the forum that when the battery is replaced you look for the best one but the question nobody asks is: where is it built? With what quality controls?
It would take a ranking (and perhaps there is already on the web) that, outside of advertising purposes, certifies which are the best batteries and above all how to recognize them.
In this italian site:
https://www.dns-ok.it/batteria-moto#migliori-5-batteria%20moto-confronto
There are different brands of batteries (and battery charger / maintainer) and as you can see at the bottom of the page, Yuasa there is not only one type and brand; so Yuasa manufactures different models but not only ... produces different brand Yuasa batteries (Yuasa Battery CO. LTD, Yuasa, Yuasa Battery).
PS: sorry but I try to translate complex concepts well, tell me the quality of the translation so I can correct myself, thanks.
