Well my initial post you replied to was precisely about phone batteries if you would be so kind to read it again. So...
>All I am saying is there is a market for these things once the specs are open and user can choose themselfs.
And I told you already that the market has existed for a long time and is now flooded by low quality fakes and knockoffs that can set your house on fire. So we need legislation to force manufacturer to sell original batteries to the consumers instead of having consumers go online or to dodgy corner shops and risk buying dangerous fakes.
The fire brigade attending the scene told me that the only reason the neighbour survived the blast was due to him recharing the battery in a spare bedroom. The explosion nearly vapourised the bedroom door, threw what remained of it out, and it blew the window frame out as well. There was a gaping hole on that side of the building. Luckily, the ordeal took place seven stories below me, but, no, I do not want the same thing to happen anywhere in the nearest vicinity ever again.
No, it doesn't console me that phone batteries are smaller, and the physical damage would be less. If a dodgy battery in someone's phone explodes whilst their are handling the phone in their hands, I do not want to wish anyone to be that person who could lose a limb, an eyesight, an eye (or both), or a permutation thereof. People do stupid things, and some will do absolutely them one day (i.e. manually installing a dodgy knock-off battery into their phone and accidentally shortening the contacts).
With a real battery from someone like Samsung i know who I can hold accountable and sue for damages when that happens. Especially since Samsung has a legal entity in my country. But good luck doing anything with Lucky Star Battery LLC China.
>There are however, and always have been, reputable third party companies that make replacement batteries
Which are the ones that make reputable phone batteries?
I saw a YouTuber buy half a dozen iphone 6 batteries off the internet and all were found to be fake or original refurbished with significant wear.
