Yesterday I replaced my 4-year-old OEM battery. Man are they expensive! Got battery tender leads coming and will be adding that to the bike when they arrive. No more guessing. I'll have a full charge every time I take her out.
Hoping to get pics tonight of the things I did over the weekend. Gotta mow the lawn and overseed it before the rain comes in tonight.
Just be wary of keeping it on a tender
ALL the time when you're not riding!! :lecturef_smilie:
If you generally ride for 30+ minutes or so & include at least
some Highway/out of town speeds in that, &/or you're only leaving your Spyder un-ridden for less than a week or so, then your battery will be better off in the long run if you leave the tender disconnected between those weekly longish runs; but if you're leaving it sit for longer without said 30+ minute ride in the next week/10 days or so,
ONLY THEN should you consider connecting it up to the tender for 8-10 hours or so every now & then! :thumbup:
Leaving any battery, even a brand new battery, connected for an extended time to a tender that
DOESN'T have an automated '
Maintenance Cycle' can rapidly kill the battery, and many have found the 'surface charge' those sorts of tenders can give even just a mildly discharged battery can often let you start at OK home, letting you ride off without a care in the world; only to discover that the battery is dead/incapable of res-starting the engine once you stop it & then try to start it next time!! :gaah: This is more likely to happen if you don't usually ride it for long enough to 'close to fully' charge the battery and so replenish the drain from starting it (only how long that might need can vary from battery to battery, altho it's
usually AT LEAST 30+ mins of riding at a reasonable speed!

) So if you leave it on a tender whenever you aren't riding, you might just find that you can start up and head off OK, only to find that if you ever stop while you're away from home, it just won't start again, leaving you stranded &/or looking for a jump start!! :banghead:
So get yourself a quality Battery
MAINTAINER (rather than just a 'tender'

) and if you're planning on riding your Spyder again within the next week or so,
DON'T connect it to the tender/maintainer at all, and
DO try to make sure you put in at least one good 30+ minute ride every week or so!

hyea: Do that, and a good quality battery should easily last a fair bit longer than just 4 years (my batteries rarely see a tender/maintainer and usually last
at least 8 years!

) altho if you have an annual lay-up period cos it's too cold to ride, that'll probably shorten its life expectancy a bit anyway - batteries don't really like sitting around unused, especially if it's cold, and they do have a finite number of 'reliable charge/discharge cycles' in them... altho how many that number actually is can vary from battery to battery & usage patterns too!! How long is a piece of string; or a short wait vs a long wait?? :dontknow: Just like battery life, both of those depend on a whole lot of variables, but
we do KNOW that leaving your battery connected to a tender
ALL the time between rides is a sure-fire recipe for getting caught out with a dead or dying battery when you're a fair way away from home, and also might kill them earlier than expected! :lecturef_smilie:
Just Sayin' :thumbup:
Ps: The OEM Spec batteries supplied by BRP since about 2020 are nowhere near as good as the earlier 350 CCA 21 A/hr Yuasa's they used to supply, so you should try to make sure that any replacement that you get is
AT LEAST specified as highly as the earlier Yuasa's detailed above! :2thumbs:
Good Luck! :cheers:
