Re: (ET) T105 capacity vs BB600

["Dave & Deb" <daveb drizzle com>]

Ok I gotta finally ask.  what are flooded NiCd's?  I know what NiCd's are,
I am quite familar with flooded lead-acid and I always thought "flooded"
refered to being "wet".  Are thes NiCd's wet??  Does flooded mean
something other than what I've thought all these years??
thanks,
Dave
