You might want to measure the operating current of the tool while drilling to make sure the current stays mostly under 20A maximum. You can also just measure the voltage across the battery pack terminal. LiIon is nominally 3.7v per cell. For 5 cells, you should see 18.5 volts. If you just charged the battery to it maximum save voltage of 4.1V, you'll see 20.5V. The "20V" rating is from marketing, which believes that bigger numbers sell better but decimal points create confusion. -- Jeff Liebermann jeffl@cruzio.com PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558 |

I don't sleep well anymore, ad I'm waiting for cataract surgery on both eyes so I miss some typos. I'm sitting less than eight inches from a 24 inch monitor to be able to read text. |

Comcast offers up to gigabit service in my area, but I don't care to pay for it. I haven't canceled the DSL because AT&T has grandfathered it.. if I shut it down, I can't ever get it back, and I have a good deal. Streaming on one device works OK, and you certainly don't need any faster for e-mail or Usenet, unless uploading large attachments. |

The one on the TV has (had) an indicator stating that it must be replaced visible after the strike. Yes, it has been replaced. Peter Wieck Melrose Park, PA |
| Charlie+ <charlie@xxx.net>: Oct 02 11:32AM +0100 The tool driver Li-ion 2Ah and 4Ah packs are in Lidl UK at the moment. Anyone happen to know how many cells (in series) these really are? They have quoted an ambiguous 20V voltage, could be either 5 or 6 series cells.. anyone know or can measure the charged volts - Thanks C+ |
