    A number of people (I'm one) use CTEK charger/minders. You can leave them on all the time the car is standing and they keep the battery fully charged without over-charging the battery (as some cheaper 'minders' will).

    On the face of it, this makes sense, but try getting an accurate reading from the battery. Problem is that it is in the boot, and if you open the boot, you immediately activate the boot lock motor and illuminate 2 boot lamps for 10 minutes, each drawing 1A. In all probability you will have just unlocked the car, which has repositioned the powerfold mirrors and put the vehicle system into get ready for action mode. So, just getting access to the battery has taken down the surface charge. I don't think I've ever measured more than 12.0v across any battery I've had in the car since I bought it.

    That was only a guesstimate, just tirying to suggest once you are in the 11. something range, you can start getting Amber light warnings from different modules. Eg park brake not available , abs etc, due to low voltage sapped away by starter motor taking voltage down to 10ish volts, modules aren't happy with low voltage and won't play? lol

    Yes, but you shouldn't have to do that for a relatively young car left for a short period. In contrast, of my 2 ancient MX5s, one started on the button after sitting for 8 weeks in an unheated garage. The other struggled a little, and needed a boost. But thats ok, its still on the original factory fit (1993) Panasonic AGM battery

    At temperatures below or around 0C the engine requires a significant amount of current to turn it over and, assuming it starts first time, at least 15-30 mins normal ‘unloaded running’ to recover. Under low temp/short useage running conditions it is very wise to trickle charge each night. When I forget to do this, my V8 will occasionally stall when selecting selecting drive for the first time and can often take some ‘coaxing’ to restart. Hope this is reassuring.
