Hello together, at the Dacia, EZ ’07, my Holden has long announced the death of the first battery (start problems, if the box is longer, so a week and more, while otherwise everything is tiptop) and this morning after the long weekend (so the intervals are also shorter) it was time, he wanted a small donation from my car. 😉 Anyway, I ordered a new battery, made me smart about the battery exchange, everything best so far, only me the hint is very pleased, that I can support the on-board voltage during the operation with another battery or a charging device, that I do not have to reprogram radio afterwards again etc… I don’t have both now, only for camping and crafts a small lead battery, 12V, 7Ah. That would have to be enough, right? The car won’t pull that much electricity if ignition is off, no consumer runs etc… Look forward to your assessment! 🙂
