Sorry for the delayed response, I've been away... I was under the impression that the back ups were lithium ion, in which case my point would be correct. Thanks for clarifying.

I cannot agree with the suggestion that it flattens the battery more
to leave the unit turned off. These are lithium primary cells with a
shelf life of well in excess of 10 years. In other words, if you
don't take any current from them, in 10 years they still have
significant power left in them. If you discharge some power from the
battery then once it's gone, it's gone - the lifetime will reduce.
All the manufacturers' data I have on lithium primary cells supports
this view.
If the backup batteries were lithium ion or lithium polymer secondary
cells then the answer may be different.
