I forgot about the 80% discharge part, thanks for catching that.

If you only discharge the first 40%, I bet you could get the efficiency up.
This doesn't apply to NIMH though, speaking of which why do they put these in hybrids?
they should use NiCds.

The main reason for them using the NiMh is the chemistry. They are way less dangerous. Cadnimum is a very bad thing, and MUST always be handled like the poison it is. Worse than lead paint!!
NiMh also loose their standing charge slower than NiCds do.
But possibly the more important reason is that they only last about 500 cycles before they start wearing out :-)
Lithimum is coming along just fine, once those have been around a bunch more years, they'll be better in the long run.
Price is what keeps them out of my reach.

Cheers
