Spotted in the Sun an "intelligent" battery charger here
It looks a lot like my ctek one but at around £15 cheaper.

for an extra fiver, I'd go for an accumate

I bought one like that in a different colour from Aldi for £12.50 last week. Lidl also sell the same one for about the same price occasionally.

That looks just like the one I bought at Lidl a few weeks back.

Aldi have car stuff next week:- http://www.aldi.co.uk/uk/html/offers/offers_week3thursday09.htm

No battery charger though.
