Excuse the thread bump, but saves starting another with the same title.
I note above that a Ctek 0.8 charger has been recommended, which is £20 cheaper than a model slightly higher up in the range - the MXS 3.8.

I'm wondering if it is worth spending the extra money for my needs. I have an Odyssey AGM battery which I need to revive after leaving it standing for several months which I'll then need to trickle charge as well as being able to occasionally charge 12v car batteries (2L or so) in cars which I have sat around for long periods.
It's a catch 22 between paying £30 and wishing I'd spent more and thus end up buying 2, or paying the £50 for the 'better' model but then not using any of the additional features that the £30 one wouldn't have so I'm unsure which suits my needs the best.
