flat battery

different things

but it will charge it fully over time?

I believe it does if you leave it long enough. I've used it to recover flat batteries in a few hours. It even put enough juice into my GSXR in 20 minutes so that the bike would start. But the battery wasnt completely discharged in that case though.

i have the 2 green lights, but going to leave it on

either till tomorrow or monday

what then? take it for a spin and leave it then try the day after?

i have a big rideout planned for saturday, so i may need a push

the two lights on mean the battery is as charged as the optimate will get it, not that it will start the bike. Charge it enough to start the bike, take it out for an hours run and leave the bike for a day and see if it discharges. If it does the battery is being drained off by something or is knackered (and as you haven't added anything recently i'd say it's knackered).

Once the green light comes on it means it has stopped demanding 90% of the charge current it began with. It is still charging, and then will go into conditioning mode, where it will monitor the batteries self discharge rate, then charge again. The red 'knackered' lamp can come on many hours later after it has evaluated for a while. This doesn't always mean the battery has failed, but that something has been drawing current whilst the evaluation has been going on. If this occurs the test is to remove the +ve lead from the battery to the bike, or remove the battery, and try again. Leaving it connected for days or weeks at a time is nothing but beneficial.
