Query: Poor service life

My experience with these 18 volt DeWalt 18 volt batteries has been poor to say the least.Spent close to $300.00 for the original drill and battery set and the original batteries stroked out in a very short period of time. just long enough for the battery warranty to have expired.The battery charger worked just fine and was not the fault of the charger. I have had a Skill battery power drill with the original batteries that lasted close to 6 years and cost a fraction of the Dewalt setup. The cost of replacement batteries is outrageous in my opinion. So here is the choice you get faced with either spend another $100 bucks on new batteries or chunk the drill and go to another brand.DeWalt is a big name brand but the quality of the product i bought was very poor.I am sure there are thousands of very satisfied customers out there at a heavy price tag but I am sure there are those of who feel they have gotten their shorts burned off.
