urtica

I use a Lacross BC-700 charger. Great charger. First, I went through all my batteries and refreshed them. It charges and discharges repeatedly until the full charge doesn't change. (Can take a few days.) Then I physically wrote on the batteries with a sharpie what their capacity was. Got rid of some, some got assigned duty as wall clock batteries, etc. But knowing what the real capacity (not just what is claimed) has been beneficial. I can match them when I put them in things. Also, every few months when I swap some out of a device, I run them through the cycle that totally drains and recharges them once to see if the capacity is reduced. Knowing which they are and pulling weak batteries out of the collection has saved me so much trouble I wish I would have upgraded to a good charger years ago. That being said, I have never had any problems with the Eneloops. They seem to hold their charges and are at least the capacity stated. And they are conveniently stocked at Costco.

I found one in Cabo (Baja) that was last logged in Michigan 2 years previously. I posted a note saying that it lived and I would wait a little in case whomever dropped it off was on vacation and was going to log it after the vacation. No log so I logged it out of the original Michigan cache and into the Cabo cache (so it could get its miles updated) and then out of the Cabo cache into my possession. Then it was treated just like any other TB; ultimately I dropped it off in a cache in Idaho after my trip.

I think we are making this too complicated. Figuring distances north or south is fairly simple, regardless of where you are. It just depends upon how accurate you want to be. Figure 69 miles (60 nautical miles) per degree of latitude (to within a percent). If you move east or west then it gets tricky. Longitude goes from zero (at the poles) to 69 miles (at the equator) per degree. If you want it down to the feet, then it gets tricky. But since your original post was about a plane's speed given in miles per hour, I was thinking you don't want it to the foot. Check out: http://members.optusnet.com.au/fmet/main/degree.html
