What about using a small solar panel?

I have something similar that has two USB charge points. It cycles the display between volts and current (for devices plugged into it).

I have a Jaycar one. It is quite useful if you don't want to fit a permanent meter.

A small solar panel is a good idea to keep a trickle charge going in and keep the battery healthy. Batteries like to receive a slow charge for a while and then have a rest, at night with solar, so it works well. You could just sit it on the dash and plug it into the cigarette lighter.

You have to have the ignition on to use the cigarette lighter outlet.

How small? The one I have gives virtually useless output. I bought it for my motorbike.

True. I should have explained that. I have an extra cigarette plug connected directly to one of my batteries.

I have an old 15amp panel I use for reviving sick batteries.

Hi Mick, is that amps or watts?

The instructions state for a battery within the vehicle to attach the negative lead to the chassis rather than the negative post on the battery. Does that mean I have to clean a patch on the chassis underneath the vehicle so I get a good earth. Where do you place the negative lead from the charger?

Also, if I only use my vehicle monthly how often should I charge the batteries to maximise my battery performance with the 7 stage charging process.

Once charged you leave it on and being a 7 stage charger it will just top up when is senses a drop in the battery as it has a built in trickle charge and I have the same charger. I personally don't think you need to go to a body earth, I don't on mine and it works fine.
