Hello, I would like to point out the following problems in this topic: According to the EU Regulation 2019/1148 (here as full text: https://eur-lex.europa.eu/…/?uri=CELEX%3A32019R1148&%3Bfrom=EN ) the private purchase of various chemicals over a certain concentration is prohibited from 1.2.2021. Among them also sulfuric acid >15% concentration, which is used for refilling car batteries. Before the 1.2.2021 acquired stocks can still be owned until 01.01.2022. the possession of sulfuric acid >15% illegal. So those who still have old, non-maintenance-free batteries should take advantage of the opportunity and still cover themselves with sufficient material. By the way, this ban does not apply to sulphuric acid, which is in car batteries (see https://fulbat.com/new-regulation-for-the-sale-of-acid-for-batteries/ ) VG
