Paging - Optimate3 isti

Been loaned an Optimate3 to keep battery topped up while Brother is out of
the country for six months. No instructions, just the device.
Lights on left 'power' and 'polarity'. Understood.
Connected it all up, light on right 'charging' came on. Good.
Left it overnight now showing 'maintenance - weak' rather than
'maintenance - good'.

Can anyone with the appropriate instructions for an Optimate 3 tell me what
the difference in the battery is betweeen these two maintenance lights?

thanks

Dave

Pretty much what you did.

This is only an opinion mind but sort of sitting here and seeing the odd
question like this come up and in the end of it there be no real answer
other than "I went back and did it all again and now it works, would
anybody care to explain why?" ISTM there are some as yet undefined set
of conditions where optimates just refuse to function for a day in the
manner they are expected to.

I'd be inclined to wire up a bulb or something and drain 2 or 3 ampere
hours out of the battery tonight and leave it to rest for half an hour
and bung it back on the charger in the morning and see what happens.

There is some bad news though. A couple of times recently when this
question has been asked it has turned out to be the optimate broked
down.
