Query: Weak, battery hog, and all around useless tool!

I have a few B&D; 18volt tools and I decided to buy a weed whacker and this electric broom. I was in for a surprise.The weed whacker works great and the battery lasts for ever...as an FYI!I charged the battery the day I received it...a full charge of about 18 hours..to be on the safe side. Put the battery in and went on to do my cleaning around the deck etc.... Yes there was air...it was OK..but not enough to sweep much. 15 minutes later it went to half power, and 10 minutes later it DIED.My first reaction - the battery is bad, lets try a different one and if that is the case I can call B&D; for a warranty replacement. NOT the case...all batteries in this thing died in less then 30 minutes and thus this is useless for me.Other B&D; 18volt tools, including the weed whacker work for 45 minutes plus and usually have full power for the first 30 minutes.Sorry B&D; but this is useless, IMHO. 1/5
