Default GL450 battery goes dead

Hi everyone - the battery in my GL450 goes dead in about 2 days if I don't run the bike. At idle, the charging system is putting out 14.2 volts, at 5000 rpm its putting out 13.5 volts. I'm not sure what I should check next, or even if this is ok. Any idea what might be causing the battery to die ?

How old is the Battery? If it's more than a year or two old, it might be going-away. The 13.5v is a little low, but not wholly unheard-of.

Do you keep the bike on a trickle-charger when it's parked?

The charging voltage looks fine, about what you'd expect with a healthy system.

It's possible you have a short circuit that is draining your battery.

Or your battery might just be done. No fix for that, just replace it.
