Lightweight car battery

As I see we have similar thoughts about many things. :)
I made a research about lightweight batteries few years ago and I found that all of them are overpriced and the weight saving wouldn't be so huge to worth deal with all the troubles (mounting, terminals, charging differences, etc). Finally I bought one of the lightest conventional battery Varta A16 which is only 9,7 kg and also very cheap. You can use the original mounting with it either. The weight saving was quite remarkable since the previous battery was over 17 kg. I used it for a while but its 340 A CCA is too little for cold winters (under 0°C), and I also had some hot starting issue that I could not resolve.
Now it has been replaced with Varta C6. The 520 A CCA seems enough, but it is also 2 kg heavier than A16.

5,5kg + the weight of the mounting, if you want to be precise, but it is unimportant. This is also a conventional lead acid battery for racing cars. It has only 156 A CCA. I had more than double and I had issues. I would not recommend anything under 300 A CCA for a road car, but 400A would be better.
There are no miracles. For lead acid battery weight = Capacity and CCA. If you really want to lose weight you should use a lithium battery. E.g: http://voltphreaks.com/catalog/product_info.php?cPath=24_27&products_id=34
But these are much more expensive and a different charger is also required.

I found this on eBay. Says rally cars looks more geared to motor bikes. Expensive as well

Try the Varta A16. You won't risk too much money on it and you will get valuable experience.
Anyway, what kind of battery do you use now?
