Participant12.73v for my batteries is
12.73v for my batteries is the fully charged state based on the infomation supplied by the manufacturers not 12.6v and this is what i see every morning after the batteries have been at rest overnight for 12hours. Prior to installing the system on this paricular van i was getting a reading of 12.35 which is just below 70% charge for my batteries. I personally was quite dubious about the claims made about standard voltage regulation and how it was just adequate in terms of the amount of charge potential it has, so i have regulary checked it.
Fortunately cold weather is not a concern of mine as i never have problems starting in temps down to as low -25 even with the battery that comes with the van. However i will admit that i do not know what the CCA rating is for my starter battery and i have strangely enough never asked any of the people i have jump started in the alps what their cca rating is either. I will however check mine later as it possible this might be why it’s so easy to start in the coldest of temps.KS

Participant10% plus or minus
Hello againMy previous battery experience agrees with the figures of up to 14.4v charging, around 12.6v for a resting battery and dropping to 12.1v min under a light load – it’s just the way a 12 volt battery is made. 12.73 volts on a meter would be quite possible though, as electronics are built to a price and usually allow themselves 10% plus or minus. So this is well within range.
Everyone should carry jump leads and a thick tow rope of course (plus sand ladders and maybe a winch outside Europe) for self recovery and being helpful. I hesitate to mention it though, but as my original post suggested, if you camp alone then by using a ‘big switch’ charging circuit you don’t need a second vehicle as long as the leisure battery isn’t flat. You might wait all day for any passing traffic and that might be a donkey cart… It’s tough jump starting from a donkey..!
However you power it – enjoy your camping
