 Run Time June 7, 2011
By MarkR
The DC9181 was cheaper than the other Lithium battery DC9180. The DC9181 only has 1.1 amp hour run time and the DC9180 has 2.4 amp hour run time just like the ni-cads. The DC9180 is lighter than the ni-cads and not much more money than the DC9181 and has twice the run time.

Lithion Battery Not 100% compatible September 17, 2010
Amazon Verified Purchase

This battery does not work in the portable vacumn cleaner, battery does not fit correctly due to the design of the plastic end plug. Different than the old metal hydride battery. Works great in the rechargeable drill and reciprocating saw, small half the size of regular battery and light weight.

Light weight, light run time March 28, 2011
Amazon Verified Purchase

After receiving the battery, I was very enthused about using it. It appears about half the weight of standard Lith-Ion battery, and makes for a nice feel in my impact driver. I was a little disappointed with the run time, maybe about half the standard time, but I still like it's compactness and light weight. What else would you expect for half the battery! Besides, I have 2 standard batteries if I need extended running time!

Compact battery - Works as intended November 5, 2011

This battery works great with my 1/4" Impact driver. It's smaller and lighter than a standard 18V DeWalt battery. Those who criticize the weight and run-time may have missed the point. It's smaller so it is lighter, charges faster, and fits the DC825B driver perfectly. The larger batteries are compatible with the DC825B, but they extend beyond the footprint of the DC825B.
