Query: A Good Choice

My Dewalt drill still works fine but the original batteries were not holding up well. I wanted to buy one of the new hammer drills such as the Hitachi DV18DL 18-volt Lithium-Ion 1/2-inch Cordless Hammer Drill. But since they are expensive, I also want to get it or something similar on sale. So, I decided to replace the battery on the Dewalt. This battery is as others have described as being much better than the original, being stronger and holding a charge longer. I don't think I really need two batteries for the amount of time I use the drill. I also am not in a hurry to buy the new drill. The new battery is a little heavier, but the weight at that location on the drill seems to provide good stability. I thought the battery was a little pricy, but you probably get what you pay for. We'll see.
