Good job you don't know me thenI've been using Optimate maintenance chargers on bikes for many years and never had a battery fail, 8 years is the longest I can vouch for before selling the bike (with original battery)
Or me! Sadly the Kwack can go three or four months between rides, the alarm / immobiliser used to flatten the battery inside a fortnight. Within the first year the battery was dead due to constant discharge and recharging, I bought it a new battery and an Optimate problem solved. I bought the bike new in 1997 so the replacement battery must have been in service for eighteen years.
