Battery charge through 'cigar lighter' socket

Does anyone know if the socket is on/live when ignition switched off - my battery almost flat (3rd occasion- only out on sunny days) so thinking about a trickle charger via 12v ' lighter' socket. Two questions - first is it feasible and secondly, if so, what charger is recommended by our readers?

It is not live with the ignition off.

I have an Optimate on my bike all year round and it keeps the battery in perfect condition all year round. I have had mine for around 10 years now and never had a problem. It has also been used to resurrect batteries which were thought ready for the scrap heap (sorry, responsible recycling) as well.

The type of Optimate required will depend on the Ah of the battery. Just bought an Optimate 5 for my Mother-in-Laws 110Ah caravan battery from a Honda main dealer via eBay so came Honda branded but was about half the cost

You can either attach it to the battery using the standard 'croccodile clips' or fit the supplied plug in socket which makes life much easier

I keep meaning to test the power socket in the boot which only the sportswagons have, I have been told that they say live.

If the new battery drains then that will be the first thing I will try. If not I will be looking for a live cable to cut into which isn't turned off.

I use a solar charger which I bought from Maplins on my LR Discovery, has crocodile clips to connect onto battery. Works very well topping up battery whenever there is solar radiation. Have left car for weeks before now and always starts on the button.

The crocodile clip to the battery version, as Phillh suggests would be my choice too.

For a permanent solution you can hardwire the existing socket to a permanent 12V supply, as long as there's a fuse in line and you don't forget to remove any accessories when you park !
