help buying

I can pick up a used EVT R30 2009 Model. Owner wants to sell because new job is out of range. Ran for abou 18 months for a little under 750 km /450 Mi.
Several questions, is there is there a group U1 battery (I think) with more than 35 amps that would be a drop in replement. I suspect I need to change the batteries soon.
What is real world range and speed. Bike and I am in Florida so cold is not issue, heat may be. I have a 25 mi @ 30 mph or so range.
Any issues with chargint this out side, if I can get permission to charge at work.
Anything else in general I should ask about
