Famous last words. You just know as you're writing them that they'll come back to bite your @r53. So Quick run out for a message on Saturday (of course it chucked it down while I was out too for good measure) and on return I switched the bike off before opening the garage door. I usually I let it idle and cool/equalize temperatures a bit, but hadn't been far so thought no need. Quick tidy in the garage before restarting the V which sounded a little lazy on the startup. Retested the battery, and yup, battery has a 35% state of health, but at least its holding 98% charge on that 35%
. New battery time, as I don't want to get stranded anywhere. Decided to try one of them there Lithium jobbies, as it has a 3 year guarantee over the one year for a lead acid one, and only £4 more expensive. (I know there may be cheaper lead acid ones, but we are held over a barrel here with who will send you a battery and if indeed they are able to, never mind the excessive postage costs). I am going to wait before replacing the optimate though, as it's nearly the same price as the battery, and supposedly the Lithium won't discharge as quickly as as a lead acid. Time will tell.
