My battery went flat during the week. Sounded a bit sluggish starting in the morning, even more sluggish starting to go home, then dead next time I tried it. I’ve had it on the Optimate and it says it’s “weak”. A bit of a surprise at only 18 months old and bike used most days.
Do I accept that the battery is at fault and get a new one or does it suggest a fault in the charging system? How do I go about checking that using a multimeter and a complete lack of technical competence!
