Anoying 'beep"

[steve@19806]

2004 Columbia, new batteries.....when charging and charger has entered the "finishing mode" a faint beeping is heard. This does not happen all the time and has me wondering.....any suggestions? BTW, un-plugging and plugging back in does not silence the beep.

Where is the sound coming from, at the area of the charger or under the dash?
The Delta-Q charger does not have any beeping sounds during the charging process and the noise location may help me.
