07Sierra Posted August 21, 2013 Report Posted August 21, 2013 Was wondering if the DCD 985 makes the same power using any battery...Will I receive all the drill can give using any battery? I know the runtime will be shorter but heard some people say the small battery won't give you the same kinda juice as the bigger one... Can someone clear this up for me, thanks
johnarmy Posted March 30, 2014 Report Posted March 30, 2014 The amp hour only affects the run time, its the voltage that delivers the power.

Sauropod55 Posted April 4, 2014 Report Posted April 4, 2014 3.0 amps sounds like nickel metal hydride, is that what your using?
DPSElias Posted April 4, 2014 Report Posted April 4, 2014 Ideally you'll have the same power with any battery, the health of the battery will have some play, and there seems to be some slight differences if you look at the link above but not enough to think you are supercharging your drill with the 3.0 battery as the voltage is what is really driving the drill. All the batteries in the 20v line are lithium ion, so it's not NiCad, and battery life should be much greater then NiCad. If the NiCad system you had was 18v and 3.0ah battery you'd have similar run time. I hope this holds.-D 1
DR99 Posted April 4, 2014 Report Posted April 4, 2014 Milwaukee is the only company that rates the tools with more power when you use a large capacity pack compared to the compact batteries. everyone else it only effects run time. Oh this is an old post anyways 07Sierra left the forum because he didn't like the perceived Milwaukee bias here. 1

Milwaukee IS better!! I mean Festool is still better than all lower life forms but.... 1

Can someone clear this up for me, thanks http://professional-power-tool-guide.com/power-tool-forum/index.php?/topic/3865-does-a-larger-battery-give-more-power-results-inside/ Most of what is said in that thread is accurate. But to go into detail. Almost all power tool battery packs have a discharge rate. In the nicad days this was measured using "c". In some tools, the tools that have a high power - draw rate, like a circular saw you should see the tool producing more power especially under load using the "bigger" battery packs like 3AH or 4AH. because most of these battery packs (NOT ALL) are 2 slim packs slapped together in parallel. These battery packs made of 2 parallel packs together, essentially doubles the discharge rate the batter pack is capable of. Also some battery packs are actually using the same number of cells, but just larger cells in the larger packs. The larger battery cells in most cases have a higher discharge rate. Most tools under load will draw more power from the pack. If the pack is able to deliver the power required by the tool, it essentially allows the tool to produce more power, assuming the tool was power starved, which in many cases it is. also, this is not true for all tools, because some tools and battery packs have circuity that will limit the max draw from the battery and power into the tool.
