Historically, "NiCad" and other rechargeable batteries had to be "deep cycled" (completely drained before recharging) in order to avoid "loss" in total battery charge. Generally, if you discharged to 10% before recharging, when you got back down to 10%, the battery pretty much thought it was empty.
The newer rechargeables, the Lithium ones, do not have this problem. I am unaware if there is some bad effect from discharging this type of battery. I actually had a one week course on battery charging. We had batteries from the 1960s and chargers from the 1970s. (sure seemed like it, anyway, the equipment that needed batteries was from the 1950s) ciao :) --- Nicolas Lopez <[EMAIL PROTECTED]> wrote: > On Wed, Jan 01, 2003 at 09:36:29AM +1100, Tim > Bateman wrote: > > That is interesting, thanks.
