Stand alone battery charger?

Hi,
I think what your looking fore is this:
Antigravity Micro Start XP-1

You can google it for yourself, it's brought in from the US, it's available on ebay look for the UK supplier.

Does look like a handy, albeit expensive bit of kit.
The thing is if you keep running a battery flat in very cold weather it'll eventually peg out on you anyway.
