I don't think the question is sufficiently covered by a simple
Yay or
Nay answer, cos it's juuust a tad more complex than that! :lecturef_smilie:
If you're riding your Spyder every week or so, &/or
always running it for at least 30 mins or so at better than 'just poking around town' speeds, then you really shouldn't
need to use a battery tender or maintainer (and remember, those two things aren't necessarily the same thing either!

) and if you do, you may well be shortening the potential life of your battery, if not killing it! Plus, if you
always use a tender when not riding, you could easily '
hide' a dead or dying battery until it's too late! If you are doing that thru '
less than ideal/appropriate tender use', then you'll most likely only find out that your battery is no longer up to keeping your Spyder running &/or start it
when you are away from home!! So if by using a tender too much, you are actually
misusing it instead, then
Nay! :banghead:
But
if you only ever do short/slow runs, so the tender is
needed to top up the battery between rides; if you're leaving your Spyder sitting around for weeks or months at a time between longer/faster runs & your battery will be
noticeably discharging between rides; or if you're storing or laying up your Spyder for a longer while, like over an extended holiday or winter/snow season; then sure, use a battery tender, or better yet, a tender/maintainer - they can be a great device to help keep your battery in good condition and in those circumstances, your question warrants a
Yay answer! :thumbup:
So instead of a straighforward
Yay/Nay answer, it really should be a '
given appropriate use for your specific riding/charging needs/conditions, then a battery tender might be a useful tool to help you keep your Spyder & its battery in good operational condition'!
