2013 OEM battery? :shocked:
...That must have been the best battery off the assembly line that year!
:bowdown: :bowdown:
Nah, I got much the same 7+ year life outta the OEM battery in my 2013 RT, as have a few others reported here.

hyea: Only replaced my RT's battery a little while back, when it started showing signs of slow starting if I didn't ride for a couple of weeks & had just left the Spyder sitting there, not on a battery tender!
I think the trick to getting a long life from your battery is to
USE them by ryding your Spyder regularly/often; keep the battery charged up properly; and
NEVER store/leave the battery standing by starting out with less than a Full Charge!
That said, as soon as they start showing 'slow starting' symptoms, it's time to start thinking about getting a new battery. And beware,
always connecting your battery to a battery tender can be a trap, cos if it's always topped up before you try to start it up & then leave home, you'll never know if the battery is getting tired until you've stopped it while out ryding somewhere & it fails to start again!! I don't usually connect up to a battery tender unless my Spyder is going to be standing for
more than a week - and I think that regular slight drain followed by full top up charge is probably good for them/their longevity... they tend to last longer if they're regularly
USED & then Re-Charged properly, within their recommended 'state of charge' limits of course! :thumbup:
