Four years is not too bad for a motorcycle battery. Another year would have been nice; it was alway on a tender, and I live in a warm climate where is almost never gets below freezing, but an 8 year old bike getting battery #3 doesn't sound too bad.

I've been expecting mine to zonc out, 5 years is good but I have still have the original battery from when I bought the bike in April 2014. I check it regular & it's always showing 12.7v or more. I don't leave tender on, just put it on now & again. Mebbe every couple of weeks.

Now I'm hardly using mine (WFH full time, so no commuting for months), I do the same as Paul.   Leave it alone, and maybe once every couple of months when I remember I'll connect the tender up and unplug it a day or so later.  I don't think batteries really like being charged *all* the time, even if the blurb on the charger says otherwise.

I took it out for a spin a few nights ago (went down to Dungeness and ate fish and chips on the beach - crystal clear evening, to the point I could just see bits of France over the water.   Completely forgot to take any pics for a Ride Out thread though).   First ride in almost 3 months and (yet again) it just fired right up, first push of the button.

I'm on my second battery - got a whisker under 60k on the clock now, and it's almost 7 years old.   Regular use, and periodic use of the tender when you're not riding often seems to be the trick.

I'm on my 3rd battery in 13 yrs, just using a tender if I haven't ridden in over 3 weeks or so. Even when they are getting weak, they read 12.5 to 12.7 . Its when you try to start the bike that matters.  Seems to be around 10.5v when new, 10v when older, which is when the problems happen. When I see this happen, I replace the battery before the colder weather comes.
