Not really, altho it'd be better to cover it with a properly fitting cover to protect it a little from the elements & also do whatever you can to keep stray cats & other rodents off/away from it! But these things are made to be ridden in all sorts of weather in the great outdoors, so a couple of weeks standing around outside shouldn't really hurt it.... much! :thumbup:
Still, as others have said, there's a good chance that connecting the battery up to a quality Battery Maintainer (which is not really
just a Tender!) would see you back on the road - if you've got an extension lead or a nearby power outlet you shouldn't even need to take the battery out of its little hidey hole (if you had added the details of your Spyder year/model to your sig line or put that essential info in your post we could even tell you where that is!

) just disconnect the battery leads & push them out of the way, then connect the Maintainer to the battery terminals (Red to +, Black to - ) & then let it get on with it's charge/discharge thing (that Tenders don't do! ) so it'd start charging & restoring whatever life it could to your battery - 4 days or so should see your battery back up to as good as it could be given the dead flat event & the subsequent shortening of potential battery life that brings! And if you can still get the top of a beer bottle you should be easily capable of undo-ing the battery terminals to do this, quite possibly even well able to remove & replace a battery too, even without a workshop!! I generally do battery swaps outside anyway, cos I've seen what can happen if an old style wet cell battery does the wrong thing in an enclosed space - not that our Spyders have those old style batteries still, they use AGM batteries that generally can't readily do that leak/short thing as standard equipment; but still, it's a good practice to get used to so you don't ever forget!

So instead of wasting a couple of weeks sitting in your hands, you could be ryding again in just a few days, certainly enough to get your Spyder to the nearest battery/auto shop to get the battery load tested so you can find out if it
NEEDS replacement
NOW, or if you can just maintain it properly for the next few years instead - and an a/mkt battery, even if it's identical to the OEM Battery, is likely to be somewhat cheaper than an OEM/Dealer installed battery....
IF the dealers techs can even work out how to do that! :banghead: And you could
still get your Spyder looked at later, at the appointed time, after most of a couple of weeks of enjoyable ryding &/or learning more about those things you really CAN do for yourself on your Spyder!
