Anyone Use Battery tender, JR. with Gill sealed battery

[surveytennessee]

I was wondering if it was really true that a Battery Tender can mess up a Gill sealed battery. I know there is a warning with the paperwork that specifies that but would it really hurt it? It seems to me that the charging current while the plane is running would be worse for the battery than a Battery Tender. Also wouldn't a Battery Tender be better than nothing at all? Any opinions? Thanks
