Y, without knowing how/when you ride and how/if you store the bike off season it's not an easy question. I changed to a new Yuasa this year as a precaution after 8 years from the oem Yuasa. Bike batteries are killed normally by the lay up periods and not when we ride. I really dislike leaving batteries on tenders all winter and prefer to switch them on for a day every few weeks until in the case of mine it goes green-green. My 8 year old Yuasa was still going fine but that naggin battery voice was talking to me. Change it. Change it! Pffffffftttttt. Good luck with your choice, personally I'd go Yuasa and maintain it carefully. Upt.
My 1200r has been constantly connected to a c-tek conditioner when not in use since 2017 . Still on original Battery.
I've just changed mine, 2022 Pikes Peak, 22,000 miles, beginning to get a bit sluggish on cold starts, not taking the risk of getting stranded. New Yuasa £61, so £/mile pretty good really. Interestingly (or not) the battery was made 18 months before the bike was.
Agreed, get lithium. I've trickle charged it once (when it arrived) and it's been in the bike for a couple of years and has been faultless. It's a weight saving not to be ignored imo.
A battery on a tender is great as you can forget everything - until the tender goes wrong. A good battery will survive but a good battery doesn't need a tender. Dealers don't bother with them. As I have just had a terrible battery experience, I am now anti tender. I'll repair the faulty one but dunno if I'll bother use it anymore. As somebody contemplating buying a scooter my views carry no substance. Hope that's cleared up
