Have a look at his link as it tells you everything you need to know about leisure batteries.

You should never fully discharge a leisure battery if you do you may kill it.

The Lidl battery charger coming in store soon... http://www.lidl.co.uk/cps/rde/xchg/lidl_uk/hs.xsl/index_35188.htm

...is a good cheap option for keeping a battery topped up over the winter.  You can leave it connected, just check every so often because it needs to be re-set if it loses mains power for any reason.

If all you want to use it for is to maintain charge in a battery over the winter then I would say they are fine.  They will fully charge the battery then go into maintenance mode. There's no need to spend any more.

They put out a max of 3.8 Amps which means they would struggle to keep up with 'normal' domestic useage.  For that you need a charger capable of putting out maybe 10 Amps or more.  For such a charger you will pay considerably more.

I've used one of these for the last several years to maintain my boat 'domestic' (leisure) batteries over the winter.
