Yup - last time it took all day to charge up (with my decent trickle charger, off the bike). Now 10 days later, and it had less 'oomph' than last time (but I didn't measure the voltage), within 6 hours it was showing as fully charged - the charger switches off automatically and comes back on when the voltage drops below a certain point.
At 'full charge' I checked the voltage and it was 12.45V. I think it's safe to say the battery is no good.
I'll check it in the morning and check the discharge over the next week. I'm going to buy Yuasa next, as it has a good rep and a higher CCA than the Motobatt.
This battery was great for 18 months, but after a 4 month lay-up with no riding but occasional charging and starting the bike, it's a goner. Next winter if I don't ride (due to amount of salt they chuck down) I will keep the battery in the house and charge it once a week.
