    La Crosse Technology BC-700 Alpha Power Battery Charger

    topbook99 La Crosse Technology BC-700 Alpha Power Battery Charger Review.





    Handicapped version of BC9002007-08-30By NLee the Engineer (Nashua, NH)Just in case you were looking for the La Crosse Technology BC-900 AlphaPower Battery Charger: please be advised that ths is NOT the same charger.
    Except for the color, the BC700 looks exactly the same as the better-known BC900. However, it is actually a handicapped version of the old charger. Its charging current can only go up to 700mA in three steps (200/500/700). The BC900, on the other hand, can go up to 1000mA for 4 cells, or 1800mA for 2 cells. Also the BC900 package includes eight NiMH rechargeable cells (4 AA and 4 AAA), eight C/D cell adaptors, and a carrying case. The BC700 does not come with any bonus items.
    This is not to say that the BC700 is a bad product. Quite the contrary, it is better than any other NiMH AA chargers in the market except for BC900 and Maha MH-C9000. If you can find it at a substantial saving (like maybe 30% off from the price of BC900), it is still a good buy. But as it is right now, I recommend getting its older brother instead.
    [update on June 13, 2008]
    Recently the price of BC700 has settled to a level much lower than that of BC900 (partially because the price of BC900 has gone up), so it is now an excellent buy especially if you intend to buy some low-self-discharge NiMH cells separately. In light of this, the criticism in my original review now seems unnecessarily harsh. Too bad Im not allowed to change the star-rating for this product.
    [Update on April 7, 2010]
    I hope my overly critical review above did not discourage anyone from buying the BC-700. As of this moment, it is the best value if you are looking for an advanced battery charger/analyzer. This is because:
    - The BC-9009 has been recalled recently due to excessive overheating/meltdown incidents.
    - The Powerex WizardOne Battery Charger-Analyzer is more powerful, but costs twice as much as the BC-700.
    - The newest La Crosse BC500 has severely limited functions compared to the BC-700 (see my review for details), yet it costs more.





    Best charger I ever owned2008-04-29By Nuknuk (Springfield, VA United States)UPDATE: (08-11-2010) It has been more than 2 years since I wrote this review. This charger is still working great!
    I have owned at least 8 chargers in the past, Mahas, Panasonic, etc. It is nice to see that this charger shows you the mAh on the LCD panel as the battery charges up. Most chargers you only see an LED indicator to signal when charging is done.
    Compared to the specs of BC-900, BC700 can only go up to 700mAH (the max) which means it is somewhat slower than the BC900. But the faster the battery charges, the hotter it gets. And one of the worst enemy of rechargeable batteries is heat. Less heat means longer life.
    Pros:
    - 3 adjustable charging speeds
    - Will show you the actual capacity in mAh. This is good so you know which battery needs to be refreshed. You always want to use batteries with the same capacities in pair or in a group.
    - 4 independent charging stations with individual LED readouts. AAs and AAAs can be charged in different combinations. Dont you hate those gadgets that only use 3 batteries like portable radios? (walkie-talkies). You end up with 1 un-used battery if you bought a 4-pack. How will you charge it if your charger only charges in pairs?
    - Reasonable price for an excellent charger
    - Small and light. Better portability
    - Multi-volt up to 240v. Very useful if you travel a lot to other countries.
    Cons:
    Now I have to stop myself doing impulse buying on NiMhs because I enjoy using this charger too much.





    Great charger but.2008-03-03By Highlander (Canton, Ohio)This is a great charger and when I bought it it was about $15 less than the BC-900. Now the BC-900 is less than this charger. The difference between this charger and the BC-900 is the lack of the faster charging speeds and the accessories. Definitley buy the BC-900 and the accessory package for less money. It seems they are constantly playing games with the pricing on these two chargers. The BC-700 charger does a great job of reconditioning batteries and the charging speed is usually between 2-3 hours for the different capacity batteries that I have. (1800mh 2650mh). Time is not an issue for me as I have about 10 sets of AAs and can just keep swapping them out. From what ive read the slower charging speed is better for the life span of your battery any way.





    Versatile Charger Great features & works as supposed to BUT 2008-09-03By avsroyI am a medium to heavy user of AA & AAA rechargeable cells and also an early adopter started with 300mah Panny NiCds many years ago I remember the excitement when 450mah versions were released! Over the years I graduated through the technologies and was using Sanyo NiMH 2500mah cells till I recently discovered Eneloops they are simply amazing! Now back to the charger review I have always been an advocate of chargers...

One Good Turn, A Natural History of the Screwdriver and the Screw

Creator: Witold Rybczynski | House & Home - 2001-08-28

Traces the history of the screwdriver from a sketch in da Vinci's pad to a later patent and mass production.

Publisher: Scribner

About this book
The Best Tool of the Millennium The seeds of Rybczynski's elegant and illuminating new book were sown by The New York Times, whose editors asked him to write an essay identifying "the best tool of the millennium." An award-winning author who once built a house using only hand tools, Rybczynski has intimate knowledge of the toolbox -- both its contents and its history -- which serves him beautifully on his quest. One Good Turn is a story starring Archimedes, who invented the water screw and introduced the helix, and Leonardo, who sketched a machine for carving wood screws. It is a story of mechanical discovery and genius that takes readers from ancient Greece to car design in the age of American industry. Rybczynski writes an ode to the screw, without which there would be no telescope, no microscope -- in short, no enlightenment science. One of our finest cultural and architectural historians, Rybczynski renders a graceful, original, and engaging portrait of the tool that changed the course of civilization.

Publisher: Harper

About this book
Albert Einstein's groundbreaking scientific discoveries made possible the creation of the most terrible weapon the world had ever known. But he made another discovery that he chose to reveal to no one—to keep from human hands a power that dwarfed the atomic bomb. When twelve-year-old Daphne Marrity takes a videotape labeled Pee-wee's Big Adventure from her recently deceased grandmother's house, neither she nor her college-professor father, Frank, realize what they now have in their possession. In an instant they are thrust into the center of a world-altering conspiracy, drawing the dangerous attentions of both the Israeli Secret Service and an ancient European cabal of occultists. Now father and daughter have three days to learn the rules of a terrifying magical chess game in order to escape a fate more profound than death—because the Marritys hold the key to the ultimate destruction of not only what's to come . . . but what already has been.
