I&#8217;m pretty sure that current tools use Ni-Mh not Ni-Cad.<br \/>\nSo the Ni-Cad argument is outdated anyway.<br \/>\n<i>Well, the Ryobi&#8217;s are still Ni-Cad (according to the warnings in the manual)&#8230; not sure about others. &#8211;dan<\/i><br \/>\nLi-Ion discharge is rated not in amps but in &#8216;C&#8217;. A 1C discharge means the battery is<br \/>\nempty in 1 hour. At 2C, empty in 30 min. These days the top of the line<br \/>\nLi-Ions discharge at 10-15C while being 80% efficient. That means the Li-Ions are<br \/>\ndead in 4-6 minutes of use. Obviously any higher discharge rate and the tool would<br \/>\nbe pretty useless.<br \/>\nThe real question is cost. A case study: There is a 22.2V Li-Ion that dumps 25 amps.<br \/>\nThat&#8217;s 555 Watts or almost 1 HP. That&#8217;s one serious battery operated tool. And the<br \/>\nbattery only weights a bit over 1\/2 a pound. The problem is the battery costs $145.<br \/>\n<i>Also, don&#8217;t miss <a href=\"http:\/\/www.danshapiro.com\/mt\/mt-comments.cgi?entry_id=116\">Frank&#8217;s helpful comments<\/a> on the matter. &#8211;dan<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Just thought I&#8217;d put in my 2 cents on Li-Ion batteries.<br \/>\nTo sum it up, they rock.
