G'day Raytech and swoop223,
Thank you for your responces, all very helpful. How do i tell if the batterys are bad?? Is there a way of testing the batteries?? The lift has fits and starts, sometimes it will run all day without losing much charge at all - just the regular amount you would expect - it will still self lift while travelling forward or backward as explained in initial post though. Other days it will not work at all, fully charged of the charger it will give 0% charge once the charger is disconected. Confused!!!
