BR>Good stuff, thanks. I'll certainly keep for reference though I am hoping for
BR>simple solution that works with V-Reg (i.e. trickle) unless I can locate an
BR>ASIC that does the fancy stuff with variable loads. (?)

Unless you want to sacrafice Reliability there is NO other Way. BUT if
you don't care about CEll life then go with the 10% of mAH for a
starting trickle charge point and make downward adjustments for any cell
heating.
At a minimum you will need a two step charger. One for the actual
charging of the discharged cells and another or the Storage trickle.
Rembembering that the cells should bacicly be at room temperature while
on Long term trickle charging.

BR>My application consists of two parallel banks of 5 cells each (single
"A"
BR>NiMH pulls, probably from older Laptop packs or similar) for 6 VDC {at} 6 AH (y
BR>each cell is rated 3.5AH so I'm assuming I can get at least 3 AH each).

Wherw dod yuo locate the "A" cell batteries? I don't recal seeing that
size. IF yuo mistypes and ment "AA" where did yuo find the 3500 mAH
cells. the largest ones I have ran across are 2300. Althouhg they are
making advances. In days past 800 was concidered GREAT.

BR>I have a Timex Diehard (flashlight that plugs into AC and kicks on
BR>automatically when power fails or when it's pulled out for use) that used
BR>rechargeable NiCds originally. I replaced them with two of these
"A" NiMH ce
BR>a year ago and it's working great still. Circuit seems to be a simple trickl
BR>charger using V-Reg  ... no heat issues to date.


LUSK of the Dray .I tyoicley have fond that those Rechargable enwegancy
lights of that typs get Far to warm best reliability. After val lthey
are "Emergancy Lights" so what good are they if Heat destroys their
capacity(Run Time)
