HAllo, after yesterday my battery problems caused me, I actually wanted to look around for a new one, but then came up with a device, that the sulfation with lead-acid batteries can undo (partly) again. Information about this can be found on the manufacturer’s homepage, http://www.novitec.de/ (click on “megapulse” on the left) The references are not bad, does someone have experiences?? In the workshop you should ask better nciht, a new battery brings more Turnover as the device costs about half of a new battery. Yesterday at a Volvo meeting it was also recommended to me by someone who built it in. But still skeptical…. What do you think of it??? Ciao, Eric
