As Pete says, because the voltage you measure with no load on the battery doesn't tell you very much about how it will behave when you ask it to deliver current to a fairly heavy load (like a motor). What happens is the voltage suddenly drops much lower....and the reason it's easy to get confused is because when you take the load back off and try to measure battery again the voltage will have bounced back up to something that looks quite reasonable .
