Question: Why so many negative reviews?
Document: I have purchased many tools from Amazon but this is the first time I have felt the need to comment on one. Just had to warn people so they don't get burned like we did.
simply put, the 36 volt is the strongest cordless system available. the tools really perform like corded tools.i have many batteries from when these first came out. my first battery finally died on me, but i have no complaints as it has gotten used a lot, and its 4 years old.the batteries do have a 2 year service plan.
Several years ago I bought my husband several 36volt tool sets and batteries. He already had the 18volt tools and was very happy with them. We have so many batteries for both sets that we keep them in the heated shop bathroom, each on an individual charger, so they don't freeze during the winter. Well we had the first three 36volt batteries drop dead one at a time after the first year. We had 4 batteries but one was still hanging in there.
the saw kit came in two days... the battery took 8.... both were free shipping... saw kit had a 2 yr old battery and the solo battery was 2010....finally a warranty item with the proper date........36V NANO is the way to go !!!! !
i bought this battery in jan 13' to use in a dewalt impact gun. I spent $128 for a used like new battery it came in the pkge. The battery was manufactured in 2006, but you cant know  that till you buy it. It lasted under light use once or twice a month to do lug nuts(which it would do all my tires on an f350 and still have charge to spare) till jan 14, at which point it died.
Wonderful wonderful product. DeWalt packs are top of the line like their tools, but I've never used any batteried thing as powerful and great! I recommend this to Professionals looking to get the job done twice as fast as any other cordless tool.
What can I say ..... it works and was a great price! I use dewalt cordless for everything and have been very satisfied with their products over the years.
WE ALL KNOW THAT DEWALT 36 VOLT PACK A LOT OF POWER.THE NANO TECHNOLOGY ASSURES LONG LASTING LIFE AND DURABILITY.ON MOST OF MY JOBS I USE THE 36V ON HARD MODE CONSTRUCTION.THIS BATTERY GETS THE JOB DONE WITHOUT RECHARGING IT EVERY MINUTE.
Too damn expensive in the first place and terrible realiability. Complaints all over the internet, so don't say have never heard of this problem. I have friends in carpentry and electrical business that have had Makita and Milwaukee tools that have had batteries that have also lasted 10 plus years....
This purchase was just fine. I got the battery pack in good time, it was well packaged for shipment, it works as it should. I am pleased.
