Update & more questions...

I picked up an Optimate 4 yesterday & tried it on my friends Honda Falcon 400 which I've been looking after for the past couple of years while he's out of town. The battery died on me in March from lack of use and has been sitting in he garage since. I removed the battery & when I hooked it up the bottom left red light came on indicating that the battery was 'deeply discharged or neglected'. After the 30 minute retention test the red 'test' light came on. The guide states that the battery is dead or needs a professional service, so I disconnected. Should I have left it attached for a while to try my luck or just give up on it?

Second question. I've removed and plugged in the XTX battery...which has the green light staying constant after the retention test with showing a voltage of 13.54v...all appears to be well as expected from a 5 month old battery. It's been plugged in for 5 hours now...is this enough, should I disconnect, if so how often should I plug it in. I wont be installing the battery for a little while now as winter has set in.

Thanks
Denny
