I don't know much about Lithium batteries (vs lead acid), apart from being lighter what else justifies the price?
I use my car about once a week on average, and for the rest of the time it's on a battery conditioner plugged into the 12v supply on the dash. I understand that Lithium batteries don't need conditioners as they don't discharge when not in use, but I guess there is still a small draw from the ancillaries even when the ignition is off - how long can it be left before it drains the battery?
I don't have power in my garage so can't use a battery conditioner. I do use a Battery Brain to disconnect the battery but a lead acid will still discharge. The lithium should last longer with this regime which is why I went for this one.
Re the time to discharge - if you have the immobiliser you are probably looking at 3-4 weeks to a point where it may well fail to start.
Performance wise, I don't really any difference to the lead acid other than in the cold weather it seems to keep cranking without feeling strained for much longer if that makes sense?
