It's not a jimny so I need help.

I have need of its 3 tonne towing capacity 4 times a year and I need it to work then. The rest of the year I would like it to work for whenever I feel like taking it out, I don't want to feel forced to use it when it would be better to use the jimny just to keep the cruiser happy.

If you fit a C-Tek on permanent charge the battery will be charged as and when you need it. You will not need to drive it to charge the battery, the charger does it for you. as I said earlier, outflank the bugger.

And as I said before it would be my elderly and disabled parents who would bear the brunt of connecting the charger as they are the main users of the car. The opportunity to get it wrong or forget is high and not really fair on them which then means me looking after it which I hardly have time for. Ultimately I'm of the opinion that a land cruiser of all things should be able to just be used even if only for 25 miles a week without intervention. Had I known before buying it it was going to do this I wouldn't have bought it.

And as I have said before, I am a realist, I don't batter my head against a wall, I look for a door. Fit the C-Tek permanently to the car with a simple extension lead to a suitable power point and put a note on the steering wheel telling the driver to disconnect it.

What is wrong with wanting my car to be right? Why should I have to have my vehicle devalued, because I can't currently sell it in good faith knowing it has a fault?

Next question. If the battery is rated as 75Ah and I placed a draw on it of 1 amp it will maintain that for 75 hours?

But does it have a fault?

It has a draw on the battery which is within the manufacturers specification when not in use, it has been designed to be used in a certain way as agreed with the manufacturers algorithm. you are (potentially) wanting to use it outside of that algorithm, is that a fault?

Is there an option to fit a larger battery, is there a winter option for twin batteries, I thought some LC had them, our Surf did, but it was an import. 

With regards to the charger I get the impression that you think that it will be a hassle, having to open the bonnet, connect the leads etc. I'm not sure that is what is being suggested if it is then I am with you, but what I would expect to be provided is a discrete plug/socket in the grille, under the bumper etc. that you would simply connect the lead. As you are towing I presume you have an electric socket, depending on how it's been wired you could potentially introduce 12V at that point which would go all the way back to the battery.

I suspect that if you used the car on more regular basis then there would be no issue, which means you could should you wish sell the car with a clear conscience, however I would also suggest that whatever you replace it with is likely to have the same issue.
