Thanks Ron I will check with the manufacturer

Only charge in situ if your charger specifically says it can.  Most cheapy ones can't, and you run the risk of electronic damage (ask poor Mrs Chrisgixer )

After batt reconnection, youu will need to reset windows and sunroof, and enter radio code back in.

As long as you disconnect one of the battery terminals first you can be fairly confident that any charger can be connected to the battery without harming the car's electronics.

Disconnect both terminals if you are particularly worried.

Thanks for the clarification my charger is a rather expensive one which is said to be a conditioner so maybe I have been lucky not to have caused problems.

You do need to check.  TBH, even with shitty chargers, 9 times out of 10 you'll get away with it.  But when you don't, it can get expensive quickly

As my Ctek chargers came with a lead intended for permanent connection to a car battery I keep my Smart's battery on more or less permanent charge while in situ 

I must have had half a dozen or more cteks (or different models/capacities), because everyone says they are fantastic.

Sadly, my own experience doesn't match that, and I wouldn't but another, nor have I replaced any since losing the last ones in the garage.

My powersounder started chirping at me now and again recently 
Having Triskaidekaphobia it was no great surprise that at about 12.30AM 13th December ,my Omega alarm sounded in all it's glory 
turned it off with remote a few times , even locked it with a key
(so the alarm would not arm  )
by 2am I had the bonnet up ,removing the wiper arms to get at the powersounder 
Un-plugged it AND the horn sounder next to it too, just in case

I needed the Omega the next morning , so put the wipers back and left the sounder bolted in place, I will remove it (and replace the batteries /fit under and over current disconnect protection and an off switch if ,once examined/autopsied I think it's worthy) ** ,probably over crimbo

**Awaits multiple OOFers saving bin the crappy 90's electrical folly that is "the powersounder"

Remove it and drop in a bucket of water/beat to a pulp with a club hammer.

The get on with more important stuff.

Leaving it in the car, however unplugged is not recommended as the odds are firmly on the internal batteries leaking. And that corner of the bulkhead is the last place you want an battery goo...

Thank you for the Advice DG 
I will definitely remove it soon ,did not consider the leaking batteries / potential for my Omega to become rusty 
 
I will however dremel it open and have a look-see inside and decide if I want to up-date the  guts OR
 "drop in a bucket of water/beat to a pulp with a club hammer"

If only I had saved the bucket I reversed over (pre bucket avoidance camera fitting)
it would have been ideal 

[Doctor Gollum]

Nah, the club hammer is far more satisfying... But the bits go everywhere

at 2 am in the morning, freezing my nads off ,I did briefly consider the club or claw hammer to remove the scuttle 
 proximity of the expensive screen ,and it being the 13th ,fortunately male logic kicked in/dictated a slower,less damaging approach

There are a few different types, all look identical from the outside, but internally take different batteries etc.

TBH, not worth the effort, and with global warming and all that BS, we need to fill landfill more to raise the ground level.

I can't throw something in the bin without taking it apart first ,see how it works etc

I live on a hill, so not worried about global warming raising water levels 
and, it's getting cold now, so anything we can do to warm the globe up has to be good ,

Plug it back in then... there's enough Omega to heat the drive for at least a day...

I'm Doing my bit for global warming , I've allowed Mrs Builder a lump of coal for the fire 
the Koi are at 15 degrees in the fish house pond, even the cat has under-bed heating 
suspect i will be raped by the electric company early next year

I have decided to put a new battery on, the present one was fitted 7 years ago. I can remember when if you got 2 years you were doing well.To prevent loss of radio etc I have in the past connected my 12 volt golf battery to the connecting leads before removing the battery.You worry me about blowing up the electronics on the car .Should I just take the battery out without a back up and then reset whatever needs doing.

[Andy B]
