Steve, that little one you saw in my car was a Varley Red top 25.
One of these:
Varley Red Top 25 Battery 12V - 7065-0017
Been great for me, holds charge well and cranks my little xflow no probs at all!
Plus quite a bit lighter than your big truck battery

I can not believe a little match box battery, can produce more cranking power than a heavy lead battery
So I will have to pop over and try it out !

smallest varta silver?

Have smallest on in kit now, only few months in so no idea on how it will do in the long run.
Also make sure you have no current drain as this could be you problem.
Same as top flight bosh ones but less money.

Have been thinking of batteries so will watch with interest.
Thing that concerns me is the electric fan that can run on for quite a few minutes after a run.

Well it starts my car fine!
feel free to pop round and have a demonstration!
Have a look here:
http://www.varleyredtop.com/pdf/batteries.pdf
So to be fair it does appear to be quite a low CCA, but again, has continued to start my engine without any problems as long as it's got a
decent amount of charge in it!
Could always opt for a 30 instead of 25....

Cheap batteries are only designed to last 2 years better quality batteries with longer warranties (anything from 3 to 7 years) are better
quality do last longer.
But a 085 battery is really huge 100 ah 800+ CCA ---- really more appropriate for 4 or 5 litre diesel the next size down in the
same style is the 096 but even that is huge by petrol engine standards normally with a 2 litre petrol type 065 or 075 is more than enough.
These days I tend to buy blue or siliver top Exide or Bosch/Varta batteries with a 4 or 5 year warranty from Tayna.
Every-time you take charge out a battery you reduce the amount of charge it will hold on recharge and the longer the delay before recharging the
more damage is done.
Normally unless more than about 30% of the charge is used and the engine starts and is running and charging the damage is not significant.
The rule of thumb is after a difficult winter cold start the engine needs to run for 20 minutes to replace the charge, so when with a winter start
up on a kit car a kit car it is wise to charge the battery before starting and after.
You should check the alternator is not over charging .. ie no more than output in no more than 14.9v acrooss the batter at 2,500 rpm and
above.

i find myself doing the same with race mini (no alternator)
last one i bought was a BOSCH one for about £75 from costco S something
065 is about as heavy as you need
roughly a ford transit spec i think
i charge it prior to use and it lasts a whole day which is 17 miles 
dad has just replaced the battery on the locost
its not even finished lol
it rattled off the ledge on the hot exhaust whilst setting carbs up and put a hole in it
IC
measure twice, cut once, scrap it, start again.
