Hello, on my SUV with the 2 years old Banner Running Bull 59201 12 V 92 AH was no longer possible to start. All ads were extinguished. – Charging cable, 2 hours highway – goes again – but is not full. I read a lot negative of this AGM battery during research, which should therefore have a very low durability! Would it now like to charge with a charger fully or regenerate. Which charger from Bosch from C3 to C7 is also here from the charging power and the latest technology on the e Most recommendable? Is the C3 sufficient? But it’s not about the most affordable, but the best! Are there any findings in the meantime whether a charging current of 14.4 is sufficient or it still has to be 14.8 at AGM. Thank you.
