So i post here, hoping somebody could answer or give me a part of answer... as it seems this forum is only made of enthusiasts

[iMP-350] Remplacing "Ni-Mh" with "Li-ion" batteries
I've got an iMP-350 player for about 2 years.
But today, the original batteries only last about 5h30 or 6h whereas they should (?) last about 23 hours (really???)
As said on this page:
http://www.iriver.com/product/info.asp?p_name=iMP-350
"Runs up to 23 hours with 2 NimH rechargeable batteries(including auxiliary battery pack)"
well in fact i didn't really understand this sentence... does that means : the TWO batteries PLUS the auxiliary battery pack last 23 hours, so let's say 8 hours for the batteries and 15 for the pack ???? i don't know 
OK. But my question was if it's possible to use "Li-ion Polymer" batteries (as in the H series) instead of the Ni-Mh, because Li-ion batteries last longer.
Well another STRANGE thing, is the reference to the "memory effect" that have NI-Mh batteries.
Here: http://www.iriver.com/support/faq_vi...word=batteries
"A major advantage of NiMH battery technology, apart from lack of toxicity, is the absence of any memory effect - NiMH batteries are remarkably tolerant of frequent 'top-up' charging."
Well, ok. But a more recent document: http://www.iriver.com/support/faq_vi...p;word=battery
says:
" -. Why is Li-ion Polymer Battery selected?
1) No memory function and long lifetime (vs. Ni-Cd, Ni-Mh).
Stick battery such as Ni-Cd and Ni-Mh has memory function."
WTF ?!!!
So anyone got an answer to this ? Or the iRiver staff ?
Please
