I'm open to suggestions to be honest! I don't see how the original SORN document can have had anything to do with this really given that it was essentially part of the general process of "getting the V5" and surely any system should be able to see that the date of SORN on the original document pre-dates me having taxed the vehicle...isn't that the whole point of having to put the "effective from" date on the form in the first place...
Not really likely to actually affect anything given I'm still several key components away from a test run, but annoying nontheless.
Speaking of components, I now have a battery.
Sadly all the "normal" car batteries anywhere around here had were significantly too big in at least one dimension. 063 would be good if the dimensions listed were to the extremeties of the flange around the base rather than the body, sadly they're not - so there's no way it would fit properly.
I really wasn't worried about terminal layout or type. The battery leads are plenty long enough to fit either way around and swapping the terminals is trivial. It's currently got the quick release post type on there purely because they happened to be floating around in the box of miscellaneous electrical junk and were useful as I was still sharing the battery with other vehicles. I reckon the spade type with the connection bolted directly on is probably superior in terms of long-term electrical quality, even if it is a bit more fiddly to initially set up.
I wound up picking up a U1-R. Simple reasons being that it was the only thing I could find locally which would definitely fit* and it was relatively inexpensive compared to the "normal car types" for some reason.
* It will require a bit of adaptation on my part. The U1 looks to be
very close in terms of dimensions to the original battery, however it lacks a securing flange. I'll make up some spacers to sit at either end from some Foamex board, and will probably look at making a strap to go over the top held down by the clamps from some scrap metal.
You can see it looks to be reasonable in terms of scale.
Not massively smaller than a 038, but the dfference is visible.
So specification wise it's 30Ah (as per the original) rather than 35 for the 038, but otherwise there's nothing between them really - aside from the fact that the U1 is very noticeably lighter 7.8kg vs 12kg, and in a tiny car like this that can only be a good thing I think.
Might think about using one of these next time the C5 needs a new battery - I reckon the weight reduction may well offset the slightly lower capacity in that role.
