Normal
I have one I keep on my Harley all the time and only once in a while I will disconnect it and put it on my KTM but that never seems to need much of a lift. I also have a 25 foot extension cord running the tender and like mentioned above these do not draw any amps to worry about. I have had mine for 15 years and I bought it at Interstate Battery and I believe it will charge at 1.25 amps and then go into storage mode once fully charged because it has brought life back into close to dead batteries.
