Actually it may have done the battery some good! Leaving the ignition switched on doesn't drain the battery very quickly
and if you've used a modern 'smart' charger to charge it back up then the battery should not have suffered
any ill-effects. I have a battery here which is the spare for my BMW motorcycle and that's been on the 'smart' charger
continuously for over a year......I tested it a few weeks back and it spun the Boxer engine over very well!
So I doubt very much that your battery will have been damaged. HTH
