Having had some issues with finding my battery not able to start the bike after just 7-10 days not being ridden, I decided to do some tests.
I took it off the bike and charged it up with a decent trickle charger. After charging (in the evening) the voltage was 12.47 - in the morning it was 12.31V
I charged it through the day each day for 3 days and every day the voltages were pretty much the same in the evening after unplugging the charger, and in the morning.
I then left it for 3 days and measured the voltage each morning. The voltages were 12.31 then 12.28 and finally 12.26 this morning.
When I put it on the bike, it started without hesitation. I switched it off and restarted several times and each time no problem. I then went for a 20 mile ride, at speed, and measured the voltage - 12.42V
From a voltage point of view, is this okay?
Of course, I will monitor the voltage over the next days to see how much it drops with the bike not being ridden, but if it is not enough (it does seem a little low to me) already, then I might as well just get a new one. This battery is a Motobatt and is 2 years old.
Thanks for any help.
