Battery conditioner use

[Speed 3]

I have a battery conditioner hooked up to the Tuscan on the drive. I have it on a timer to come on 3 nights per week for about 8 hours each. I set it up that way in the belief a battery should never be left on continuous "charge". Should I have it mains on permanently and would it regulate itself on & off ?

Reason for asking is the imobiliser has locked itself out and I'm told that whilst that is normally a random TVR-ism, it is sometimes associated with a dead battery.

Thanks, suspected that was the case.
