Hi Minty,

The theory is that fast charging batteries conditions batteries for fast
discharge. Also a 4 or 5 hour charge is not fast. A one hour or less charge
is fast.

For an 1800 mah cell. (NOTE: Efficiency isn't 100% so add more time or more
current. 20% to 40%)

Slow charge rate C/10 180ma for 10 hours (12 to 14 hours)

Quick charge rate C/3 600 ma for 3 hours (3.5 hrs Watch the
battery temp.)

Fast charge rate 3C 5400 ma for 20 minutes. (Should be only used
with a 'Peak Charger'.)

I have a charger with standard and quick charge features for my 7.2v
model
car battery pack. Which charging method is better for the life of the
battery pack, standard charge at 10-12 hours or quick charge at 4-5 hours?
I
charge the pack mostly on standard charge with occassional quick charge.
My
1800mAH battery pack is still in good condition after 3 years. I seemed to
have read somewhere nicads need to be quick charged from time to time for
whatever reason.
