   Saw this thread just after replying to a Li-ion thread.

   From the link in the first post:

   Quick Charge Time
   15 Min. or less with 2.4 Ah Ni-Cd
   10 Min. or less with 2.0 Ah Ni-Cd or smaller
   30 Min. or less with 2.0 Ah Ni-MH or smaller
   60 Min. or less with 3.0 Ah Li+ or smaller

   Note that the quoted charge time for a 25% higher A-H Li-ion to NiCd is 4X. Reading between the lines this says that the charger aint too kind to Li-ion.

   Even if they sold for 10% of the asking price would NOT put a Li-ion battery on this charger.

   I do have a Lister NiCd charger that retails for over $300 that does a great job on any type NiCd or Pb/H2SO4 battery.

   Not too sure what you are saying about the "aint too kind to Li-ion"

   Is a slower charge hard on the battery?  Seems I have usually read that fast charging was harder on batteries than slow charge.

   I must be missing something here - first time for that      lol

   I like the idea of having one charger that could charge four different kinds of batteries.  Not sure I buy into their claims of increasing life and runtime and reviving old batteries.

   Any further insight is appreciated

   "aint too kind to Li-ion"

   What I meant was that with good technology, you can charge a Li batt fast.  What the specs say between the lines is that they have a "cheap to implement"  Li charge algorithm, which also means the Li is not being charged at the optimum rates, and possibly at the wrong voltages.
