Battery Maintenance/Float Charger Connected While Battery is Removed

[jim628]

hi:

I am planning to charge my X5 battery with a rather high AMP battery charger. In order to avoid damaging the electrical system, i plan to disconnect the battery and completely remove it from the car. In addition, before i remove the battery , i plan to connect my BMW advanced charging system (float charger) connected. I will leave this float charger connected while the battery is removed.

My question is, is it save to do this? Will this damage the electrical system, especially the expensive electronic control unit of the car?

Thanks
Jim
