having two drills and a driver i have encountered no problems with these units, the only negative is battery just dies - loses charge without warning, had to replace an 18v light weight battery - jeez almost $100 per - one battery finally gave up the ghost. i am sure there are issues from time to time - s@@t happens. would I have craftsmen pro cordless which is heavier. thats the reason for dewalt.
After reading some of these comments about the compact batteries i had to say something about these batteries. Some people may not know about electricity but I do and if you look at the bottom of the batteries it tells you that these batteries have a 20 watt-hour rating. Now most batteries are rated by amp-hours not watt-hours. If you do the conversion this is only about 1.1 amp hours, which is not a very big battery. Dewalt labels this battery as compact, for its lightweight batteries. Batteries are only as strong as the amount of metal inside of it, so if you have less metal you will also have less runtime. This battery is the same quality as all the other Dewalt tools I have owned. Very high quality!
I was somewhat surprised to read all the reviews that said the battery didn't last long. maybe i got lucky but i've had this impact driver/ drill combo kit for about 8 months and love it. I am an hvac installer and use the impact driver on a daily basis, and literally use it all day to assemble sheet metal duct work. The battery itself lasts fine for me and if i had to guess i could probably drive 200 quarter inch screws into 26 guage metal doubled up (s-lock or drive) or whatever else the battery itself lasts to do the job and can get a whole day out of it with continuous use. The impact driver is great. just bught the hammer drill tonight. Good job DeWalt
Pros: light weight, fast charge time, good battery life, great for tight spaces
Do NOT buy!!! This battery is awful, do not buy. The charge holds about half as long as regular NICD. I thought it might have just been a bad battery but after exchanging it for a new one same problem. Coming to find out the better battery for the same price ?? DC9180 is alot better. Don't make the same mistake I made purchasing this battery.
