Batteries can still read good volts even when they've lost a cell.
Also check the output from your Alternator and Regulator/ Rectifier when the bike's running. If they're out of spec, that can kill a battery.
Personally, as I keep my bike in the shed and it doesn't get ridden regularly, I have an Optimate Tender which keeps it topped up and checks everything is ok.
He has a 20 year old battery. His bike deserves a present. :lol
